Why 18-Wheeler Accidents in Yolo County Are Different

The Physics of Devastation

An 18-wheeler isn’t just a big car. It’s a 70-80,000 pound missile traveling at highway speeds. When that mass collides with a 4,000-pound passenger vehicle, the results are predictable and catastrophic.

Consider the numbers:

• Stopping distance: A loaded truck at 65 mph needs approximately 525 feet to stop—nearly two football fields. A car needs about 300 feet.
• Impact force: An 80,000-pound truck carries roughly 80 times the kinetic energy of a typical car.
• Fatality rate: When trucks and cars collide, 76% of fatalities are occupants of the smaller vehicle.

These aren’t statistics to us. They’re the reality our clients face every day.

Yolo County’s Unique Trucking Risks

Yolo County sits at the crossroads of major California freight corridors. Interstate 5—the primary north-south artery for the entire West Coast—runs directly through the county, carrying massive volumes of commercial truck traffic between the Pacific Northwest, California’s Central Valley, and Southern California. State Route 113 and Interstate 80 also serve as critical freight routes connecting the Bay Area to Sacramento and beyond.

This geographic position creates unique dangers for Yolo County residents:

• High-volume corridor fatigue: I-5 through Yolo County sees relentless truck traffic, with drivers pushing hours-of-service limits
• Agricultural freight pressure: The county’s position between Central Valley farms and Bay Area/Port of Oakland markets creates time-sensitive cargo demands
• Interchange complexity: The I-5/I-80/I-113 junctions create merging and lane-change hazards
• Rural road dangers: County roads connecting to major highways see heavy farm equipment and truck mixing

We know these roads. We know where accidents happen. And we know how to investigate when they do.

Types of 18-Wheeler Accidents We Handle in Yolo County

Jackknife Accidents

A jackknife occurs when the trailer and cab skid in opposite directions, with the trailer folding at an angle like a pocket knife. The trailer swings out perpendicular to the cab, often sweeping across multiple lanes of traffic.

Jackknife accidents account for approximately 10% of all trucking-related deaths. They often result in multi-vehicle pileups when the trailer blocks multiple lanes. Once a jackknife begins, it’s nearly impossible for nearby drivers to avoid.

Common causes in Yolo County:

• Sudden braking on I-5, especially during Central Valley fog season (November-February)
• Speeding on curves near the Yolo Bypass
• Empty or lightly loaded trailers more prone to swing
• Improperly loaded agricultural cargo shifting weight
• Brake system failures from deferred maintenance
• Driver inexperience with emergency maneuvers

FMCSA violations we prove:

• 49 CFR § 393.48 – Brake system malfunction
• 49 CFR § 393.100 – Improper cargo securement
• 49 CFR § 392.6 – Speeding for conditions

Rollover Accidents

A rollover occurs when an 18-wheeler tips onto its side or roof. Due to the truck’s high center of gravity and massive weight, rollovers are among the most catastrophic trucking accidents.

Approximately 50% of rollover crashes result from failure to adjust speed on curves. Rollovers frequently lead to secondary crashes from debris and fuel spills. They’re often fatal or cause catastrophic injuries to both truck occupants and other vehicles.

Yolo County rollover risks:

• I-5 curves near Dunnigan and Zamora
• State Route 113 transitions between agricultural fields
• Top-heavy agricultural loads (tomatoes, almonds, rice) shifting on turns
• Liquid cargo “slosh” from wine, olive oil, or other Yolo County products
• Driver fatigue on long Central Valley hauls
• Overcorrection after tire blowout on hot summer pavement

FMCSA violations we prove:

• 49 CFR § 393.100-136 – Cargo securement violations
• 49 CFR § 392.6 – Exceeding safe speed
• 49 CFR § 392.3 – Operating while fatigued

Underride Collisions

An underride collision occurs when a smaller vehicle crashes into the rear or side of an 18-wheeler and slides underneath the trailer. The trailer height often causes the smaller vehicle’s passenger compartment to be sheared off at windshield level.

Among the most FATAL types of 18-wheeler accidents. Approximately 400-500 underride deaths occur annually in the United States. Rear underride and side underride are both deadly; side underride has no federal guard requirement.

Yolo County underride dangers:

• I-5 traffic slowing suddenly for agricultural equipment crossings
• Trucks entering/exiting distribution centers near Woodland and Davis
• Night driving on unlit rural stretches of State Route 16 and 45
• Fog season visibility issues (November-February)
• Inadequate rear lighting or reflectors on older trailers

FMCSA/NHTSA requirements:

• 49 CFR § 393.86 – Rear impact guards required on trailers manufactured after 1/26/1998
• Guards must prevent underride at 30 mph impact
• NO FEDERAL REQUIREMENT for side underride guards (advocacy ongoing)

Rear-End Collisions

A rear-end collision occurs when an 18-wheeler strikes the back of another vehicle or when a vehicle strikes the back of a truck. Due to the truck’s massive weight and longer stopping distances, these accidents cause devastating injuries.

18-wheelers require 20-40% more stopping distance than passenger vehicles. A fully loaded truck at 65 mph needs approximately 525 feet to stop. Rear-end collisions are the second most common type of large truck crash.

Yolo County rear-end risks:

• I-5 congestion near Davis and Woodland exits
• Sudden slowing for agricultural equipment on rural roads
• Driver distraction from dispatch communications on long hauls
• Fatigue on overnight runs through Central Valley
• Brake failures from overheating on long descents

FMCSA violations we prove:

• 49 CFR § 392.11 – Following too closely
• 49 CFR § 392.3 – Operating while fatigued
• 49 CFR § 392.82 – Mobile phone use
• 49 CFR § 393.48 – Brake system deficiencies

Wide Turn Accidents (“Squeeze Play”)

Wide turn accidents occur when an 18-wheeler swings wide (often to the left) before making a right turn, creating a gap that other vehicles enter. The truck then completes its turn, crushing or striking the vehicle that entered the gap.

18-wheelers need significant space to complete turns. The trailer tracks inside the path of the cab. Drivers must swing wide to avoid curbs, signs, or buildings.

Yolo County wide turn dangers:

• Downtown Woodland intersections with tight corners
• Agricultural processing facility entrances on rural roads
• Distribution center access roads near Davis
• Construction zones with narrowed lanes
• Driver inexperience with trailer tracking in agricultural areas

Blind Spot Accidents (“No-Zone”)

Blind spot accidents occur when an 18-wheeler changes lanes or maneuvers without seeing a vehicle in one of its four major blind spots (No-Zones).

The Four No-Zones:

1. Front No-Zone: 20 feet directly in front—driver cannot see low vehicles
2. Rear No-Zone: 30 feet behind—no rear-view mirror visibility
3. Left Side No-Zone: Extends from cab door backward—smaller than right
4. Right Side No-Zone: Extends from cab door backward, much larger—MOST DANGEROUS

Tire Blowout Accidents

Tire blowout accidents occur when one or more tires on an 18-wheeler suddenly fail, causing the driver to lose control. Debris from the blown tire can also strike other vehicles.

18-wheelers have 18 tires, each of which can fail. Steer tire (front) blowouts are especially dangerous—can cause immediate loss of control. “Road gators” (tire debris) cause thousands of accidents annually.

Yolo County tire blowout risks:

• Extreme summer heat (100°F+) on I-5 and rural highways
• Long straight stretches causing heat buildup
• Agricultural hauling with heavy loads
• Underinflation from drivers rushing between loads
• Aging tires on owner-operator equipment

FMCSA requirements:

• 49 CFR § 393.75 – Tire requirements (tread depth, condition)
• 49 CFR § 396.13 – Pre-trip inspection must include tire check
• Minimum tread depth: 4/32″ on steer tires, 2/32″ on other positions

Brake Failure Accidents

Brake failure accidents occur when an 18-wheeler’s braking system fails or underperforms, preventing the driver from stopping in time to avoid a collision.

Brake problems are a factor in approximately 29% of large truck crashes. Brake system violations are among the most common FMCSA out-of-service violations. Complete brake failure is often the result of systematic maintenance neglect.

Yolo County brake failure risks:

• Long descents on I-5 from the Grapevine area
• Mountain grades on Highway 16 and 20
• Agricultural hauling with frequent stop-and-go
• Deferred maintenance on thin-margin operations
• Brake fade from overheating on summer runs

Cargo Spill/Shift Accidents

Cargo spill and shift accidents occur when improperly secured cargo falls from a truck, shifts during transport causing instability, or spills onto the roadway.

Cargo securement violations are among the top 10 most common FMCSA violations. Shifted cargo causes rollover accidents when center of gravity changes. Spilled cargo on highways causes secondary accidents.

Yolo County cargo risks:

• Agricultural products (tomatoes, almonds, rice) shifting in open trailers
• Liquid loads (wine, olive oil, dairy) sloshing on curves
• Heavy equipment on flatbeds with inadequate tiedowns
• Time pressure from perishable cargo schedules
• Loading at rural facilities without proper securement equipment

Head-On Collisions

Head-on collisions occur when an 18-wheeler crosses into oncoming traffic and strikes vehicles traveling in the opposite direction.

Head-on collisions are among the deadliest accident types. Even at moderate combined speeds, the force is often fatal. Often occur on two-lane highways or from wrong-way entry.

Yolo County head-on risks:

• Two-lane rural highways (Highway 16, 45, 113)
• Driver fatigue on long Central Valley hauls
• Impairment from stimulants used to stay awake
• Medical emergencies on isolated stretches
• Passing on two-lane roads with limited visibility

Who Can Be Held Liable in a Yolo County Trucking Accident

The Driver

The truck driver who caused your accident may be personally liable for negligent conduct including:

• Speeding or reckless driving
• Distracted driving (cell phone, texting, dispatch communications)
• Fatigued driving beyond federal legal limits
• Impaired driving (drugs, alcohol)
• Failure to conduct proper pre-trip inspections
• Violation of traffic laws
• Failure to yield, improper lane changes, running red lights

We pursue the driver’s complete record: driving history, ELD data showing hours of service, drug and alcohol test results, cell phone records, previous accident history, and training records.

The Trucking Company

The trucking company is often the most important defendant because they carry the highest insurance limits and bear the greatest responsibility for safety.

Under the doctrine of respondeat superior—”let the master answer”—employers are liable for employees’ negligent acts within the scope of employment. But trucking companies can also be directly liable for:

Negligent Hiring: Failed to check driver’s background, driving record, or qualifications before putting them behind the wheel of an 80,000-pound vehicle.

Negligent Training: Inadequate training on safety procedures, cargo securement, hours of service compliance, or emergency maneuvers.

Negligent Supervision: Failed to monitor driver performance, ELD compliance, or pattern of violations.

Negligent Maintenance: Deferred vehicle repairs, ignored inspection failures, or failed to maintain equipment in safe operating condition.

Negligent Scheduling: Pressured drivers to violate hours-of-service regulations to meet delivery deadlines.

We subpoena the complete Driver Qualification File, hiring policies, training records, dispatch logs showing schedule pressure, safety culture documentation, and CSA safety scores. A poor safety record proves the company knew it was putting dangerous drivers on Yolo County roads.

The Cargo Owner/Shipper

The company that owns the cargo and arranged shipment may be liable for:

• Providing improper loading instructions
• Failing to disclose hazardous nature of cargo
• Requiring overweight loading
• Pressuring carrier to expedite beyond safe limits
• Misrepresenting cargo weight or characteristics

Yolo County’s agricultural economy generates significant specialized cargo risks. Tomato loads, rice shipments, and liquid agricultural products create unique securement and stability challenges.

The Cargo Loading Company

Third-party loading companies that physically load cargo may be liable for:

• Improper cargo securement violating 49 CFR 393
• Unbalanced load distribution
• Exceeding vehicle weight ratings
• Failure to use proper blocking, bracing, tiedowns
• Inadequate loader training on securement requirements

Truck and Trailer Manufacturers

The companies that manufactured the truck, trailer, or major components may be liable for:

• Design defects in brake systems, stability control, fuel tank placement
• Manufacturing defects like faulty welds or component failures
• Failure to warn of known dangers
• Defective safety systems (ABS, ESC, collision warning)

Parts Manufacturers

Companies that manufactured specific components may be liable for:

• Defective brakes or brake components
• Defective tires causing blowouts
• Defective steering mechanisms
• Defective lighting components
• Defective coupling devices

Maintenance Companies

Third-party maintenance companies may be liable for:

• Negligent repairs that failed to fix problems
• Failure to identify critical safety issues
• Improper brake adjustments
• Using substandard or wrong parts
• Returning vehicles to service with known defects

Freight Brokers

Freight brokers who arrange transportation may be liable for:

• Negligent selection of carrier with poor safety record
• Failure to verify carrier insurance and authority
• Failure to check carrier CSA scores
• Selecting cheapest carrier despite safety concerns

Government Entities

Federal, state, or local government may be liable for:

• Dangerous road design contributing to accident
• Failure to maintain roads (potholes, debris, worn markings)
• Inadequate signage for known hazards
• Failure to install safety barriers
• Improper work zone setup

Special considerations apply: sovereign immunity limits liability, strict notice requirements and short deadlines exist, and you must often prove actual notice of dangerous condition.

The 48-Hour Evidence Crisis: Why Immediate Action Saves Yolo County Trucking Cases

Evidence Disappears Faster Than You Think

In 18-wheeler accident cases, critical evidence has a short shelf life. Trucking companies have rapid-response teams that begin protecting their interests within hours of an accident. If you don’t act quickly, the evidence you need to prove negligence will be lost forever.

Critical Evidence Timelines:

Evidence Type	Destruction Risk
ECM/Black Box Data	Overwrites in 30 days or with new driving events
ELD Data	May be retained only 6 months
Dashcam Footage	Often deleted within 7-14 days
Surveillance Video	Business cameras typically overwrite in 7-30 days
Witness Memory	Fades significantly within weeks
Physical Evidence	Vehicle may be repaired, sold, or scrapped
Drug/Alcohol Tests	Must be conducted within specific windows

The Spoliation Letter: Your Evidence Insurance Policy

A spoliation letter is a formal legal notice sent to the trucking company, their insurer, and all potentially liable parties demanding preservation of all evidence related to the accident.

Why It Matters:

• Puts defendants on legal notice of their preservation obligation
• Creates serious consequences if evidence is destroyed
• Courts can impose sanctions, adverse inferences, or even default judgment for spoliation
• The sooner sent, the more weight it carries

When We Send It: IMMEDIATELY—within 24-48 hours of being retained. We don’t wait.

What Our Spoliation Letter Demands

Electronic Data:

• Engine Control Module (ECM) / Electronic Control Unit (ECU) data
• Event Data Recorder (EDR) data

• Failed or damaged components
• Cargo and securement devices
• Tire remnants if blowout involved

ECM/Black Box Data: The Objective Truth

Commercial trucks have electronic systems that continuously record operational data—similar to an airplane’s black box but for trucks.

Types of Electronic Recording:

System	What It Records
ECM (Engine Control Module)	Engine performance, speed, throttle, RPM, cruise control, fault codes
EDR (Event Data Recorder)	Pre-crash data triggered by sudden deceleration or airbag deployment
ELD (Electronic Logging Device)	Driver hours, duty status, GPS location, driving time
Telematics	Real-time GPS tracking, speed, route, driver behavior
Dashcam	Video of road ahead, some record cab interior

Critical Data Points:

• Speed Before Crash: Proves speeding or excessive speed for conditions
• Brake Application: Shows when and how hard brakes were applied
• Throttle Position: Reveals if driver was accelerating or coasting
• Following Distance: Calculated from speed and deceleration data
• Hours of Service: Proves fatigue and HOS violations
• GPS Location: Confirms route and timing
• Fault Codes: May reveal known mechanical issues driver ignored

This objective data often contradicts driver claims of “I wasn’t speeding” or “I hit my brakes immediately.” This data has led to multi-million dollar verdicts in trucking cases.

We send spoliation letters immediately to preserve this data.

Catastrophic Injuries from 18-Wheeler Accidents in Yolo County

The Human Cost of Trucking Negligence

The physics of 18-wheeler accidents make catastrophic injuries the norm, not the exception. When you’ve been hit by a truck in Yolo County, the injuries you suffer may change every aspect of your life—your ability to work, your relationships, your independence, your future.

At Attorney911, we don’t just understand these injuries medically. We understand them personally, because we’ve walked alongside hundreds of families as they’ve faced the aftermath. We’ve seen what it takes to rebuild. And we know how to secure the resources that make rebuilding possible.

Traumatic Brain Injury (TBI)

What It Is:
TBI occurs when a sudden trauma causes damage to the brain. In 18-wheeler accidents, the extreme forces cause the brain to impact the inside of the skull.

Severity Levels:

Level	Symptoms	Prognosis
Mild (Concussion)	Confusion, headache, brief loss of consciousness	Usually recovers, but may have lasting effects
Moderate	Extended unconsciousness, memory problems, cognitive deficits	Significant recovery possible with rehabilitation
Severe	Extended coma, permanent cognitive impairment	Lifelong disability, may require 24/7 care

Common Symptoms:

• Headaches, dizziness, nausea
• Memory loss, confusion
• Difficulty concentrating
• Mood changes, depression, anxiety
• Sleep disturbances
• Sensory problems (vision, hearing, taste)
• Speech difficulties
• Personality changes

Long-Term Consequences:

• Permanent cognitive impairment
• Inability to work
• Need for ongoing care and supervision
• Increased risk of dementia and Alzheimer’s
• Depression and emotional disorders

Lifetime Care Costs: $85,000 to $3,000,000+ depending on severity

At Attorney911, we’ve recovered between $1,548,000 and $9,838,000 for traumatic brain injury victims. These aren’t just numbers—they represent the resources families need for specialized care, lost income, and rebuilding lives.

Spinal Cord Injury

What It Is:
Damage to the spinal cord that disrupts communication between the brain and body, often resulting in paralysis.

Types of Paralysis:

Type	Definition	Impact
Paraplegia	Loss of function below the waist	Cannot walk, may affect bladder/bowel control
Quadriplegia	Loss of function in all four limbs	Cannot walk or use arms, may need breathing assistance
Incomplete Injury	Some nerve function remains	Variable—may have some sensation or movement
Complete Injury	No nerve function below injury	Total loss of sensation and movement

Level of Injury Matters:

• Higher injuries (cervical spine) affect more body functions
• C1-C4 injuries may require ventilator for breathing
• Lower injuries (lumbar) affect legs but not arms

Lifetime Care Costs:

• Paraplegia (low): $1.1 million+
• Paraplegia (high): $2.5 million+
• Quadriplegia (low): $3.5 million+
• Quadriplegia (high): $5 million+

These figures represent direct medical costs only—not lost wages, pain and suffering, or loss of quality of life.

At Attorney911, we’ve seen spinal cord injury settlements ranging from $4,770,000 to $25,880,000. These recoveries provide for lifetime care, home modifications, lost earning capacity, and the dignity our clients deserve.

Amputation

Types of Amputation:

• Traumatic Amputation: Limb severed at the scene due to crash forces
• Surgical Amputation: Limb so severely damaged it must be surgically removed

Common in 18-Wheeler Accidents Due To:

• Crushing forces from truck impact
• Entrapment requiring amputation for extraction
• Severe burns requiring surgical removal
• Infections from open wounds

Ongoing Medical Needs:

• Initial surgery and hospitalization
• Prosthetic limbs ($5,000 – $50,000+ per prosthetic)
• Replacement prosthetics throughout lifetime
• Physical therapy and rehabilitation
• Occupational therapy for daily living skills
• Psychological counseling

Impact on Life:

• Permanent disability
• Career limitations or total disability
• Phantom limb pain
• Body image and psychological trauma
• Need for home modifications
• Dependency on others for daily activities

At Attorney911, we’ve secured between $1,945,000 and $8,630,000 for amputation victims. These recoveries account for lifetime prosthetic needs, lost earning capacity, and the profound life changes our clients face.

Severe Burns

How Burns Occur in 18-Wheeler Accidents:

• Fuel tank rupture and fire
• Hazmat cargo spills and ignition
• Electrical fires from battery/wiring damage
• Friction burns from road contact
• Chemical burns from hazmat exposure

Burn Classification:

Degree	Depth	Treatment
First	Epidermis only	Minor, heals without scarring
Second	Epidermis and dermis	May scar, may need grafting
Third	Full thickness	Requires skin grafts, permanent scarring
Fourth	Through skin to muscle/bone	Multiple surgeries, amputation may be required

Long-Term Consequences:

• Permanent scarring and disfigurement
• Multiple reconstructive surgeries
• Skin graft procedures
• Chronic pain
• Infection risks
• Psychological trauma

Internal Organ Damage

Common Internal Injuries:

• Liver laceration or rupture
• Spleen damage requiring removal
• Kidney damage
• Lung contusion or collapse (pneumothorax)
• Internal bleeding (hemorrhage)
• Bowel and intestinal damage

Why Dangerous:

• May not show immediate symptoms
• Internal bleeding can be life-threatening
• Requires emergency surgery
• Organ removal affects long-term health

Wrongful Death

When a Trucking Accident Kills:

Wrongful death claims allow surviving family members to recover compensation when a loved one is killed by another’s negligence.

Who Can Bring a Wrongful Death Claim (California law):

• Surviving spouse
• Children (minor and adult)
• Parents (especially if no spouse or children)
• Estate representative

Types of Claims:

• Wrongful Death Action: Compensation for survivors’ losses
• Survival Action: Compensation for decedent’s pain/suffering before death

Damages Available:

• Lost future income and benefits
• Loss of consortium (companionship, care, guidance)
• Mental anguish and emotional suffering
• Funeral and burial expenses
• Medical expenses before death
• Punitive damages (if gross negligence)

At Attorney911, we’ve recovered between $1,910,000 and $9,520,000 in wrongful death trucking cases. While no amount of money can replace your loved one, these recoveries provide financial security for families and hold trucking companies accountable for the lives they’ve destroyed.

FMCSA Regulations That Protect Yolo County Drivers

The Federal Safety Net

The Federal Motor Carrier Safety Administration (FMCSA) regulates every commercial motor vehicle operating in interstate commerce. When trucking companies and drivers violate these rules, they create the dangerous conditions that cause catastrophic accidents. Proving FMCSA violations is often the key to establishing negligence and securing maximum compensation.

The Six Critical Regulatory Areas

Part	Title	What It Covers
Part 390	General Applicability	Definitions, who regulations apply to
Part 391	Driver Qualification	Who can drive, medical requirements, training
Part 392	Driving Rules	Safe operation, fatigue, drugs, alcohol
Part 393	Vehicle Safety	Equipment, cargo securement, brakes, lights
Part 395	Hours of Service	How long drivers can drive, required rest
Part 396	Inspection & Maintenance	Vehicle upkeep, inspections, records

Part 391: Driver Qualification Standards

Minimum Driver Qualifications (49 CFR § 391.11):

A person shall not drive a commercial motor vehicle unless they:

1. Are at least 21 years old (interstate) or 18 years old (intrastate)
2. Can read and speak English sufficiently
3. Can safely operate the CMV and cargo type
4. Are physically qualified under § 391.41
5. Have a valid commercial motor vehicle operator’s license (CDL)
6. Have completed a driver’s road test or equivalent
7. Are not disqualified under § 391.15 (violations, suspensions)
8. Have completed required entry-level driver training

Driver Qualification File Requirements (49 CFR § 391.51):

Motor carriers MUST maintain a Driver Qualification (DQ) File for EVERY driver containing:

• Employment application
• Motor Vehicle Record from state licensing authority
• Road Test Certificate or equivalent documentation
• Medical Examiner’s Certificate (current, valid, max 2 years)
• Annual Driving Record Review
• Previous Employer Inquiries (3-year driving history investigation)
• Drug & Alcohol Test Records

Why This Matters For Your Case:

If the trucking company failed to maintain a proper DQ file, failed to check the driver’s background, or hired a driver with a poor safety record, they can be held liable for negligent hiring. We subpoena these records in every trucking case.

Part 392: Driving Rules

Ill or Fatigued Operators (49 CFR § 392.3):

“No driver shall operate a commercial motor vehicle, and a motor carrier shall not require or permit a driver to operate a commercial motor vehicle, while the driver’s ability or alertness is so impaired, or so likely to become impaired, through fatigue, illness, or any other cause, as to make it unsafe for him/her to begin or continue to operate the commercial motor vehicle.”

This violation makes BOTH the driver AND the trucking company liable when a fatigued driver causes an accident.

Drugs and Other Substances (49 CFR § 392.4):

A driver shall not be on duty or operate a CMV while under the influence of any Schedule I substance, amphetamines, narcotics, or any substance rendering them incapable of safe driving.

Alcohol (49 CFR § 392.5):

A driver shall not use alcohol within 4 hours before going on duty, while on duty, or be under the influence (.04 BAC or higher) while operating.

Speeding (49 CFR § 392.6):

No motor carrier shall schedule a run requiring operation at speeds exceeding those prescribed by jurisdictions.

Following Too Closely (49 CFR § 392.11):

Drivers must not follow more closely than is reasonable and prudent, having due regard for speed, traffic, and highway conditions.

Mobile Phone Use (49 CFR § 392.82):

Drivers are PROHIBITED from using hand-held mobile telephones while driving or texting while driving.

Part 393: Vehicle Safety and Cargo Securement

Cargo Securement (49 CFR § 393.100-136):

General Requirements (§ 393.100):
Cargo must be contained, immobilized, or secured to prevent:

• Leaking, spilling, blowing, or falling from the vehicle
• Shifting that affects vehicle stability or maneuverability
• Blocking the driver’s view or interfering with operation

Performance Criteria (§ 393.102):
Cargo securement systems must withstand:

• Forward: 0.8 g deceleration (sudden stop)
• Rearward: 0.5 g acceleration
• Lateral: 0.5 g (side-to-side)
• Downward: At least 20% of cargo weight if not fully contained

Brakes (49 CFR § 393.40-55):

All CMVs must have properly functioning brake systems including service brakes on all wheels, parking/emergency brake system, and air brake systems meeting specific requirements.

Lighting (49 CFR § 393.11-26):

Required lighting includes headlamps, tail lamps, stop lamps, clearance and side marker lamps, reflectors, and turn signal lamps.

Part 395: Hours of Service (HOS) Regulations

THESE ARE THE MOST COMMONLY VIOLATED REGULATIONS IN TRUCKING ACCIDENTS.

Property-Carrying Drivers (Most 18-Wheelers):

Rule	Requirement	Violation Consequence
11-Hour Driving Limit	Cannot drive more than 11 hours after 10 consecutive hours off duty	Fatigue-related accidents
14-Hour Duty Window	Cannot drive beyond 14th consecutive hour after coming on duty	Driver exhaustion
30-Minute Break	Must take 30-minute break after 8 cumulative hours of driving	Impaired alertness
60/70-Hour Limit	Cannot drive after 60 hours in 7 days or 70 hours in 8 days	Cumulative fatigue
34-Hour Restart	Can restart 60/70-hour clock with 34 consecutive hours off	Inadequate recovery
10-Hour Off-Duty	Must have minimum 10 consecutive hours off duty before driving	Insufficient rest

Sleeper Berth Provision (49 CFR § 395.1(g)):

Drivers using sleeper berth may split 10-hour off-duty period with at least 7 consecutive hours in sleeper berth plus at least 2 consecutive hours off-duty.

Electronic Logging Device (ELD) Mandate (49 CFR § 395.8):

Since December 18, 2017, most CMV drivers must use ELDs that automatically record driving time, synchronize with vehicle engine, cannot be altered after the fact, and record GPS location, speed, and engine hours.

Why ELD Data Is Critical Evidence:

ELDs prove exactly how long the driver was on duty, whether breaks were taken as required, speed before and during the accident, GPS location history, and any HOS violations.

We send spoliation letters immediately to preserve this data.

Part 396: Inspection, Repair, and Maintenance

General Maintenance Requirement (§ 396.3):

“Every motor carrier and intermodal equipment provider must systematically inspect, repair, and maintain, or cause to be systematically inspected, repaired, and maintained, all motor vehicles and intermodal equipment subject to its control.”

Driver Inspection Requirements:

Pre-Trip Inspection (§ 396.13): Before driving, drivers must be satisfied the CMV is in safe operating condition and must review last driver vehicle inspection report if defects were noted.

Post-Trip Report (§ 396.11): After each day’s driving, drivers must prepare written report on vehicle condition covering service brakes, parking brake, steering mechanism, lighting devices, tires, horn, windshield wipers, rear vision mirrors, coupling devices, wheels and rims, and emergency equipment.

Annual Inspection (§ 396.17): Every CMV must pass a comprehensive annual inspection covering 16+ systems. Inspection decal must be displayed. Records must be retained for 14 months.

Maintenance Record Retention (§ 396.3): Motor carriers must maintain records for each vehicle showing identification, schedule for inspection/repair/maintenance, and record of repairs. Records must be retained for 1 year.

Why This Matters: Brake failures cause 29% of truck accidents. If the trucking company failed to maintain proper records or deferred maintenance, they are liable for negligence.

California and Yolo County Laws That Affect Your Trucking Case

Statute of Limitations: The Clock Is Ticking

In California, you have two years from the date of your trucking accident to file a personal injury lawsuit. For wrongful death claims, you have two years from the date of death.

But waiting is dangerous. Evidence disappears, witnesses forget, and trucking companies are building their defense right now. We recommend contacting an attorney within days, not months.

Comparative Negligence: You Can Recover Even If Partially at Fault

California follows pure comparative negligence. This means you can recover damages even if you were partially at fault for the accident—your recovery is simply reduced by your percentage of fault.

For example, if you were found 20% at fault and your damages total $1 million, you would still recover $800,000. Even if you were 99% at fault, you could theoretically recover 1% of your damages.

This is more favorable to plaintiffs than many states. But it also means trucking companies and their insurers will fight hard to assign you as much fault as possible. You need an attorney who can push back.

Damage Caps: California’s Favorable Environment

Good news for Yolo County victims: California does NOT cap non-economic damages (pain and suffering) in personal injury cases. Unlike some states that limit what you can recover for human suffering, California allows juries to award full compensation.

Punitive damages are also available when trucking companies act with gross negligence, recklessness, or intentional misconduct. There’s no statutory cap on punitive damages in California, though constitutional due process limits apply.

This means when a trucking company knowingly puts a dangerous driver on the road, or ignores maintenance failures, or destroys evidence, they can be punished financially in ways that deter future misconduct.

Why Choose Attorney911 for Your Yolo County Trucking Case

25+ Years of Fighting for Trucking Accident Victims

Ralph Manginello has been representing injury victims since 1998. That’s not just a number—it means he’s handled trucking cases through multiple economic cycles, regulatory changes, and evolving defense tactics. He’s seen what works. He’s built the relationships. He knows how to win.

His federal court admission to the U.S. District Court, Southern District of Texas, matters for Yolo County cases too. Interstate trucking cases often involve federal regulations and can benefit from federal court expertise. Ralph brings that capability to every case.

The Insurance Defense Advantage: Lupe Peña

Most personal injury firms hire lawyers who’ve always been on the plaintiff’s side. We did something different. Lupe Peña spent years working at a national insurance defense firm. He watched adjusters minimize claims. He learned their formulas, their training methods, their manipulation tactics.

Now he uses that insider knowledge against them. He knows when they’re bluffing. He knows what makes them settle. He knows how to counter every tactic they use against you.

As client Chad Harris said after working with our firm: “You are NOT a pest to them and you are NOT just some client… You are FAMILY to them.”

Multi-Million Dollar Results

We don’t talk in vague terms about “good results.” We give you the numbers:

Case Type	Settlement Range
Traumatic Brain Injury	$1,548,000 – $9,838,000+
Spinal Cord Injury	$4,770,000 – $25,880,000+
Amputation	$1,945,000 – $8,630,000
Wrongful Death	$1,910,000 – $9,520,000+

These aren’t hypothetical figures. They’re actual results we’ve achieved for clients. As Glenda Walker told us: “They fought for me to get every dime I deserved.”

Currently Litigating a $10 Million Case

We’re not resting on past results. Right now, we’re litigating a $10 million lawsuit against a major university and fraternity for hazing that caused catastrophic injuries. This case has received coverage from KHOU 11, ABC13, the Houston Chronicle, and major media outlets. It demonstrates our willingness to take on powerful institutions and our capacity to handle complex, high-stakes litigation.

Three Offices, California and Beyond

Our federal court experience and dual-state licensure (Texas and New York) allow us to handle cases that cross state lines. For Yolo County clients, we offer remote consultations and travel to California when needed for your case.

24/7 Availability

Trucking accidents don’t happen on business hours. That’s why we’re available 24/7 at 1-888-ATTY-911. When you call, you get a response—not a voicemail, not a callback tomorrow. Tonight. Now.

No Fee Unless We Win

We work on contingency. You pay nothing upfront. We advance all investigation costs. Our fee—33.33% pre-trial, 40% if trial is necessary—comes only from your recovery. If we don’t win, you owe us nothing.

As Donald Wilcox, a client another firm rejected, told us: “One company said they would not accept my case. Then I got a call from Manginello… I got a call to come pick up this handsome check.”

The Evidence That Wins Yolo County Trucking Cases

What We Preserve, Why It Matters

Every 18-wheeler accident case depends on evidence. And evidence disappears fast. That’s why our 48-hour evidence protocol is critical to your case.

Electronic Control Module (ECM) / “Black Box” Data

The ECM records:

• Speed before and during the crash
• Brake application timing and force
• Throttle position
• Engine RPM
• Cruise control status
• Fault codes indicating mechanical issues

This data overwrites in as little as 30 days. We demand immediate preservation.

Electronic Logging Device (ELD) Records

Since December 2017, federal law requires ELDs that record:

• Exact driving hours and duty status
• GPS location history
• Real-time tracking of HOS compliance
• Tamper-resistant data that can’t be falsified like paper logs

ELD data proves fatigue violations. It shows when drivers exceeded 11-hour driving limits, skipped required breaks, or falsified records. This is often the smoking gun in trucking cases.

Driver Qualification File

Federal law requires trucking companies to maintain comprehensive files on every driver, including:

• Complete employment and driving history
• Medical certification and exam results
• Drug and alcohol test records
• Training documentation
• Previous accident and violation history

Missing or incomplete files prove negligent hiring. We subpoena these records in every case.

Maintenance and Inspection Records

Federal law requires:

• Pre-trip inspections by drivers
• Post-trip inspection reports
• Annual comprehensive vehicle inspections
• Systematic maintenance programs

Brake failures cause 29% of truck accidents. If the company deferred maintenance, ignored inspection failures, or failed to keep required records, they’re liable for negligence.

Cell Phone and Dispatch Records

We subpoena:

• Driver cell phone records for distraction evidence
• Dispatch communications showing schedule pressure
• GPS tracking data confirming routes and timing
• Qualcomm or fleet management system messages

These records prove when companies pushed drivers beyond safe limits.

California Law: Your Rights After a Yolo County Trucking Accident

Statute of Limitations: Two Years to Act

In California, you have two years from the date of your trucking accident to file a personal injury lawsuit. For wrongful death claims, you have two years from the date of death.

This seems like a long time. It isn’t. Critical evidence begins disappearing immediately:

• ECM data: 30 days
• ELD records: 6 months (but often less in practice)
• Dashcam footage: 7-14 days
• Witness memory: degrades within weeks
• Physical evidence: vehicles repaired, sold, or scrapped

Every day you wait, your case gets harder to prove. We recommend contacting an attorney within 24-48 hours, not months.

Pure Comparative Negligence: You Can Recover Even If Partially at Fault

California follows pure comparative negligence. This is one of the most plaintiff-friendly systems in the nation.

Here’s how it works: You can recover damages even if you were partially at fault. Your recovery is simply reduced by your percentage of fault.

Example: If you’re found 30% at fault and your damages total $1 million, you recover $700,000. Even if you were 99% at fault, you could theoretically recover 1%.

This matters because trucking companies and insurers will fight to assign you fault. They’ll claim you were speeding, following too closely, or made an unsafe lane change. You need an attorney who can push back with evidence—the ECM data, ELD records, and witness testimony that proves what really happened.

No Damage Caps: Full Recovery for Your Suffering

Good news for Yolo County victims: California does NOT cap non-economic damages (pain and suffering) in personal injury cases. Unlike some states that limit what you can recover for human suffering, California allows juries to award full compensation.

Punitive damages are also available when trucking companies act with gross negligence, recklessness, or intentional misconduct. There’s no statutory cap on punitive damages in California, though constitutional due process limits apply.

This means when a trucking company knowingly puts a dangerous driver on the road, ignores maintenance failures, destroys evidence, or falsifies logs, they can be punished financially in ways that deter future misconduct.

Frequently Asked Questions: Yolo County 18-Wheeler Accidents

Immediate After-Accident Questions

What should I do immediately after an 18-wheeler accident in Yolo County?

If you’ve been in a trucking accident in Yolo County, take these steps immediately if you’re able:

• Call 911 and report the accident
• Seek medical attention, even if injuries seem minor
• Document the scene with photos and video if possible
• Get the trucking company name, DOT number, and driver information
• Collect witness contact information
• Do NOT give recorded statements to any insurance company
• Call an 18-wheeler accident attorney immediately

Should I go to the hospital after a truck accident even if I feel okay?

YES. Adrenaline masks pain after traumatic accidents. Internal injuries, TBI, and spinal injuries may not show symptoms for hours or days. Yolo County hospitals including UC Davis Medical Center and Sutter Davis Hospital can identify injuries that will become critical evidence in your case. Delaying treatment also gives insurance companies ammunition to deny your claim.

What information should I collect at the truck accident scene in Yolo County?

Document everything possible:

• Truck and trailer license plates
• DOT number (on truck door)
• Trucking company name and logo
• Driver’s name, CDL number, and contact info
• Photos of all vehicle damage
• Photos of the accident scene, road conditions, skid marks
• Photos of your injuries
• Witness names and phone numbers
• Responding officer’s name and badge number
• Weather and road conditions

Should I talk to the trucking company’s insurance adjuster?

NO. Do not give any recorded statements. Insurance adjusters work for the trucking company, not you. Anything you say will be used to minimize your claim. Our firm includes a former insurance defense attorney who knows exactly how these adjusters are trained to protect the trucking company’s interests.

How quickly should I contact an 18-wheeler accident attorney in Yolo County?

IMMEDIATELY—within 24-48 hours if possible. Critical evidence in trucking cases (black box data, ELD records, dashcam footage) can be destroyed or overwritten quickly. We send spoliation letters within hours of being retained to preserve this evidence before it’s lost forever.

Trucking Company and Driver Questions

Who can I sue after an 18-wheeler accident in Yolo County?

Multiple parties may be liable in trucking accidents:

• The truck driver
• The trucking company/motor carrier
• The cargo owner or shipper
• The company that loaded the cargo
• Truck or parts manufacturers
• Maintenance companies
• Freight brokers
• The truck owner (if different from carrier)
• Government entities (for road defects)

We investigate every possible defendant to maximize your recovery.

Is the trucking company responsible even if the driver caused the accident?

Usually YES. Under the doctrine of respondeat superior, employers are liable for employees’ negligent acts within the scope of employment. Additionally, trucking companies can be directly liable for negligent hiring, negligent training, negligent supervision, negligent maintenance, and negligent scheduling.

What if the truck driver says the accident was my fault?

California uses pure comparative negligence. Even if you were partially at fault, you may still recover compensation—your recovery is simply reduced by your percentage of fault. Our job is to investigate thoroughly, gather evidence (especially ECM and ELD data), and prove what really happened. Drivers often lie to protect their jobs—the data tells the true story.

Evidence and Investigation Questions

What is a truck’s “black box” and how does it help my case?

The ECM records speed before and during the crash, brake application timing, throttle position, engine RPM, cruise control status, and fault codes. This objective data often contradicts what drivers claim happened.

What is an ELD and why is it important?

Electronic Logging Devices are federally mandated devices that record driver hours of service. ELD data proves whether the driver violated federal rest requirements and was driving while fatigued. Hours of service violations are among the most common causes of trucking accidents.

How long does the trucking company keep black box and ELD data?

ECM data can be overwritten within 30 days. FMCSA only requires 6 months retention for ELD data. This is why we send spoliation letters immediately—once we notify them of litigation, they must preserve everything.

Insurance and Damages Questions

How much insurance do trucking companies carry?

Federal law requires minimum liability coverage of $750,000 for non-hazardous freight, $1,000,000 for oil and large equipment, and $5,000,000 for hazardous materials. Many carriers carry $1-5 million or more.

What damages can I recover?

Economic damages: Medical expenses (past, present, future), lost wages, lost earning capacity, property damage, out-of-pocket expenses, life care costs.

Non-economic damages: Pain and suffering, mental anguish, loss of enjoyment of life, disfigurement, loss of consortium, physical impairment.

Punitive damages: Available when trucking companies act with gross negligence, recklessness, or intentional misconduct.
