When an 80,000-pound truck loses control on Interstate 10 near Clifton, there is no margin for error. The desert heat radiating off the asphalt, the sudden dust storms that sweep through the Sulphur Springs Valley, and the endless stream of commercial traffic moving between Phoenix and El Paso create a perfect storm of danger on Greenlee County’s highways. If you’ve been injured in an 18-wheeler accident anywhere in Greenlee County—whether near the Morenci copper mine, along the stretch of I-10 that cuts through the desert, or on the winding grades of US-191—you’re likely facing the most traumatic experience of your life.

We’re Attorney911, and we’ve spent over 25 years standing between trucking companies and the families they devastate. Ralph Manginello, our managing partner, has been fighting for injury victims since 1998, and he’s admitted to federal court—experience that matters when your crash involves interstate commerce. Our associate attorney Lupe Peña used to defend insurance companies. Now he uses that insider knowledge to fight against them, giving our clients an unfair advantage when the trucking company tries to lowball your claim. We’ve recovered multi-million dollar verdicts and settlements for traumatic brain injury victims, spinal cord injury survivors, and families who’ve lost loved ones to wrongful death on highways just like yours.

The clock started ticking the moment that truck hit you. Black box data can be overwritten in 30 days. Dashcam footage gets deleted. Witnesses forget what they saw. And you can bet the trucking company already has lawyers working to protect their interests—not yours. If you’ve been hurt in an 18-wheeler accident in Greenlee County, call us immediately at 1-888-ATTY-911. We’ll send a spoliation letter today to preserve critical evidence before it disappears forever.

Why Greenlee County’s Highways Are Particularly Dangerous for Trucking Accidents

Greenlee County sits at a critical junction in America’s freight network. Interstate 10—the fourth-longest freeway in the country—cuts directly through the county, carrying everything from Los Angeles port cargo to Phoenix retail goods to Texas oil equipment. But this isn’t just any stretch of interstate. The combination of extreme desert heat, sudden weather events, and heavy mining traffic creates unique hazards that truck drivers and trucking companies often fail to respect.

The I-10 Corridor: A Pressure Cooker for Fatigue and Mechanical Failure

The stretch of I-10 passing through Greenlee County represents hours of monotonous desert driving. Truckers coming from California face the exhaustion of crossing the Colorado River, followed by the relentless heat of the Sonoran Desert. By the time they reach Greenlee County, many drivers have been behind the wheel for 10, 11, or even 12 hours—pushing the limits of federal Hours of Service regulations under 49 CFR § 395.3, which mandates no more than 11 hours of driving after 10 consecutive hours off duty.

The heat itself becomes a weapon. When temperatures in Clifton or Morenci hit 110°F—as they do regularly from May through September—tire blowouts become epidemic. Under 49 CFR § 393.75, truck tires must have minimum tread depth and be free from defects, but the extreme thermal expansion in desert conditions causes even properly maintained tires to fail catastrophically. When a steer tire blows at 75 mph on I-10, the driver often loses control immediately, sending 80,000 pounds of steel and cargo careening across lanes.

Mining Traffic and Heavy Equipment

Greenlee County’s economy has long been tied to the Morenci copper mine—one of the largest copper mining operations in North America. This means oversized loads, hazardous materials transport, and specialized heavy equipment moving through residential areas and along Highway 191. Under 49 CFR § 393.100-136, cargo securement rules require specific tiedown standards, but mining equipment often requires specialized loading that creates unique hazards on tight turns and steep grades.

Dust Storms and Sudden Weather Events

The “haboobs” that sweep through southeastern Arizona create instant whiteout conditions. Under 49 CFR § 392.14, drivers must exercise extreme caution in hazardous conditions, including dust storms, but corporate pressure to meet delivery deadlines often overrides safety. When drivers fail to pull over during dust warnings, catastrophic multi-vehicle pileups result.

The 18-Wheeler Accident Types We See in Greenlee County

Every truck crash tells a different story, but certain patterns repeat on Greenlee County roads. Understanding what type of accident injured you helps us know exactly what evidence to pursue and which FMCSA violations likely occurred.

Jackknife Accidents on I-10

A jackknife occurs when the trailer swings perpendicular to the cab, often closing multiple lanes of traffic instantly. On Greenlee County’s desert stretches of I-10, jackknifes typically happen when:

  • A driver brakes suddenly for stopped traffic near construction zones or dust storms
  • Brake systems fail under thermal stress (violating 49 CFR § 393.48)
  • Cargo shifts forward during braking, changing the center of gravity (violating 49 CFR § 393.100)

The result is often a multi-vehicle pileup involving passenger cars trapped beneath the swinging trailer. We investigate ECM data to prove whether improper braking technique or mechanical failure caused the jackknife.

Tire Blowouts and Loss of Control

“Road gators”—shredded tire treads—litter the shoulders of I-10 through Greenlee County. When a truck tire blows, the driver has seconds to react before losing control. We subpoena maintenance records to prove violations of 49 CFR § 396.3, which requires systematic inspection and repair. If the trucking company deferred maintenance to save money, that’s negligence that could cost them millions.

Rollover Accidents on Mountain Grades

US-191 north of Clifton features steep grades and tight curves through the Apache-Sitgreaves National Forest. When trucks take these curves too fast—especially when improperly loaded with mining equipment or construction materials—rollover accidents occur. Under 49 CFR § 393.100-136, cargo must be secured to withstand 0.8g forward deceleration and 0.5g lateral acceleration. Improperly secured loads shift during turns, causing rollovers that crush anything in their path.

Underride Collisions: The Most Fatal of All

When a passenger vehicle collides with the rear or side of a trailer and slides underneath, the roof of the car is often sheared off. Despite federal requirements under 49 CFR § 393.86 for rear impact guards, many trailers have inadequate or poorly maintained guards. Side underride guards aren’t federally mandated at all, creating a deadly gap where passenger vehicle occupants suffer decapitation or catastrophic head trauma.

Rear-End Collisions in Construction Zones

The ongoing maintenance of I-10 through Greenlee County creates sudden slowdowns. A fully loaded truck requires nearly two football fields (525 feet) to stop from 65 mph—40% more distance than a passenger car. When drivers follow too closely (violating 49 CFR § 392.11) or drive distracted (violating 49 CFR § 392.82 regarding mobile phone use), they slam into smaller vehicles with devastating force.

Wide Turn Accidents in Small Towns

In communities like Duncan and Clifton, 18-wheelers must navigate tight intersections. Wide right turns create “squeeze play” hazards where the truck swings left before turning right, crushing vehicles in the adjacent lane. These accidents often involve violations of 49 CFR § 392.11 for unsafe turning.

Every Party Who Could Be Liable for Your Greenlee County Trucking Accident

Most people think they can only sue the truck driver. That’s exactly what the trucking company wants you to think. In reality, multiple parties often share liability for a catastrophic truck crash—and more defendants mean more insurance coverage, which means full compensation for your injuries.

1. The Truck Driver
Direct negligence includes speeding for conditions, distracted driving, fatigue beyond the 11-hour limit, or impairment. We obtain cell phone records, ELD data, and drug test results to prove driver misconduct.

2. The Trucking Company (Motor Carrier)
Under the doctrine of respondeat superior, companies are liable for their drivers’ negligence. But they can also be directly negligent for:

  • Negligent Hiring: Failing to verify the driver had a valid CDL or clean driving record (violating 49 CFR § 391.11)
  • Negligent Training: Putting an inexperienced driver on dangerous routes without proper mountain or desert training
  • Negligent Supervision: Ignoring ELD warnings about HOS violations
  • Negligent Maintenance: Skipping brake inspections to keep trucks moving (violating 49 CFR § 396.3)

3. The Cargo Owner or Shipper
Copper mine operators, construction companies, or retailers who overload trucks or demand unrealistic delivery schedules create dangerous conditions. Under 49 CFR § 392.6, no motor carrier shall schedule a run that would require speeding.

4. The Loading Company
Third-party warehouses that improperly secure cargo or exceed weight limits (violating 49 CFR § 393.100) may be liable when shifting loads cause rollovers or jackknifes.

5. Truck and Trailer Manufacturers
Defective brake systems, faulty tires, or inadequate underride guards can support product liability claims against manufacturers.

6. Parts Manufacturers
When specific components fail—like air brake systems or steering mechanisms—the companies that made those parts may share liability.

7. Maintenance Companies
Independent mechanics who perform negligent repairs or return trucks to service with known defects can be sued for professional negligence.

8. Freight Brokers
Companies like C.H. Robinson or Coyote Logistics that arrange transportation but fail to verify carrier safety records (available on FMCSA’s SAFER website) can be liable for negligent selection.

9. The Truck Owner
In owner-operator arrangements, the individual who owns the tractor may have separate liability for negligent entrustment.

10. Government Entities
The Arizona Department of Transportation or Greenlee County may be liable for dangerous road designs, inadequate signage for sharp curves on US-191, or failure to maintain safe shoulders on I-10.

The Critical Evidence We Preserve Within 48 Hours

Trucking companies aren’t stupid. They know that ECM data, driver logs, and maintenance records prove their negligence. That’s why they have rapid-response teams that arrive at accident scenes before the ambulance leaves—sometimes while victims are still being extracted from crushed vehicles.

We fight back with immediate evidence preservation.

When you call 1-888-ATTY-911 within hours of your Greenlee County accident, we immediately send spoliation letters to:

  • The trucking company
  • Their insurance carrier
  • The driver (as an individual)
  • Any maintenance companies
  • Freight brokers

These letters put them on legal notice that destroying evidence will result in sanctions, adverse jury instructions, or default judgment.

What We’re Preserving:

Electronic Control Module (ECM) Data: This “black box” records speed, brake application, throttle position, and engine RPMs in the seconds before impact. Under 49 CFR § 395.8, ELDs must synchronize with the engine, creating objective evidence that contradicts driver lies about “I wasn’t speeding” or “I hit the brakes immediately.”

Driver Qualification Files: Under 49 CFR § 391.51, carriers must maintain files showing the driver’s medical certification, driving record, previous employer verification, and drug test history. Missing files prove negligent hiring.

Maintenance Records: FMCSA requires annual inspections and systematic maintenance (49 CFR § 396.17). If brakes were out of adjustment or tires were bald, the records will show—or the lack of records proves negligence.

Hours of Service Records: ELD data proves whether the driver violated the 11-hour driving limit, 14-hour duty window, or 30-minute break requirement (49 CFR § 395.3).

Cell Phone Records: Texting while driving is a federal violation under 49 CFR § 392.80. We subpoena phone records to prove distraction.

Dashcam and Surveillance Footage: Many trucks have forward-facing cameras. Nearby businesses on I-10 or in Clifton may have captured the accident. This footage often gets deleted within 7-14 days if not preserved.

Catastrophic Injuries and Arizona’s Pure Comparative Fault System

Arizona follows “pure comparative fault” (Section C.4), meaning you can recover damages even if you were 99% at fault—your recovery is simply reduced by your percentage of fault. This is more generous than neighboring New Mexico (pure comparative) or Texas (modified comparative with 51% bar). However, the trucking company will try to blame you to minimize their payout. We counter with objective ECM data and expert accident reconstruction.

Traumatic Brain Injury (TBI)
The force of an 80,000-pound impact causes the brain to slam against the skull. Even “mild” TBIs can result in permanent cognitive deficits, personality changes, and inability to work. Our firm has recovered between $1.5 million and $9.8 million for TBI victims, depending on severity and life-care needs.

Spinal Cord Injuries and Paralysis
When the spine is severed or compressed, victims face paraplegia or quadriplegia. Lifetime care costs range from $3.5 million to $5 million for high quadriplegia. We’ve secured settlements between $4.7 million and $25.8 million for spinal cord injury cases.

Amputations
Traumatic amputations at the scene or surgical amputations due to crush injuries require prosthetics ($5,000-$50,000 each) and lifelong rehabilitation. Our amputation cases have settled between $1.9 million and $8.6 million.

Wrongful Death
When a trucking accident kills a loved one, survivors can claim lost future income, loss of consortium, mental anguish, and funeral expenses. Arizona’s 2-year statute of limitations (Section C.3) applies from the date of death. We’ve recovered between $1.9 million and $9.5 million for wrongful death claims.

Arizona Law: What You Need to Know

Statute of Limitations: In Arizona, you have two years from the date of the accident to file a personal injury lawsuit (Section C.3). For wrongful death, the clock starts at the date of death. While two years sounds generous, evidence disappears within weeks. Don’t wait.

Damage Caps: Unlike some states, Arizona has no caps on compensatory or punitive damages in trucking cases (Section C.4.5). This means the jury can award whatever they believe is just for your pain and suffering, medical expenses, and lost wages.

Punitive Damages: When trucking companies knowingly put dangerous drivers on the road or falsify maintenance records to save money, Arizona law allows punitive damages to punish the wrongdoer and deter future misconduct.

Government Claims: If your accident involved a government vehicle (ADOT, Greenlee County trucks), special rules apply. You must file a Notice of Claim within 180 days, and the total recovery may be capped. This makes immediate legal consultation critical.

What to Do Immediately After a Trucking Accident in Greenlee County

  1. Call 911 and Request Medical Attention: Even if you feel okay, internal injuries and TBIs may not show symptoms for days. The emergency responders in Greenlee County serve vast rural areas, so document response times if delayed.

  2. Document the Scene: If you’re able, photograph the truck’s DOT number (usually on the door), license plates, cargo status, skid marks, and road conditions. Arizona’s intense sun can fade skid marks quickly, so get photos before they’re gone.

  3. Gather Information: Get the driver’s name, CDL number, insurance details, and company information. Witnesses in rural areas may be other drivers who don’t stop unless asked—get their contact info.

  4. Do Not Give Recorded Statements: The trucking company’s insurer will call quickly. Refer them to your attorney. As client Chad Harris said after working with us, “You are NOT a pest to them and you are NOT just some client… You are FAMILY to them.” We protect you from their manipulation tactics.

  5. Contact Attorney911 Immediately: Call 1-888-ATTY-911 or (713) 528-9070. Our team answers 24/7. Hablamos Español—Lupe Peña provides fluent Spanish representation without interpreters.

Frequently Asked Questions

How much is my Greenlee County trucking accident case worth?
There’s no average settlement because every case is unique. Factors include injury severity, medical costs, lost earning capacity, and available insurance. Trucking companies carry $750,000 to $5 million in coverage. We’ve recovered over $50 million total for our clients, including multi-million dollar settlements for catastrophic injuries.

Will my case go to trial?
Most settle, but we prepare every case as if it’s going to trial. Insurance companies know which law firms are willing to litigate—and they offer better settlements to those firms. Ralph Manginello has been litigating since 1998, including federal court cases and BP explosion litigation involving Fortune 500 corporations.

What if the truck driver was an independent contractor, not an employee?
The trucking company may still be liable for negligent hiring or supervision. We investigate all lease agreements and insurance policies. Many “independent” drivers are actually employees misclassified to avoid liability.

Can I afford an attorney?
Absolutely. We work on contingency—33.33% pre-trial, 40% if trial is necessary. You pay nothing upfront. We advance all investigation costs. As client Donald Wilcox discovered when other firms rejected his case, we take the cases others won’t—and we win. “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.”

How long will my case take?
Simple cases with clear liability might settle in 6-12 months. Complex litigation involving multiple defendants or catastrophic injuries can take 18-36 months. We work to resolve cases efficiently while maximizing recovery, unlike firms that drag cases out for years. As Angel Walle noted, “They solved in a couple of months what others did nothing about in two years.”

What about the heat—does that affect my case?
Absolutely. If the trucking company knew or should have known about extreme heat warnings and failed to inspect tires or schedule adequate rest breaks, that’s negligence specific to Arizona desert conditions.

Your Fight Starts Now

The trucking company that hit you has already called their lawyers. Their insurance adjuster is already looking for ways to minimize your claim. They hope you don’t know about ECM data, ELD violations, or the 49 CFR regulations they broke. They hope you’ll accept their first lowball offer before you realize the full extent of your injuries.

We’re Attorney911, and we don’t let them get away with it. With offices in Houston, Austin, and Beaumont, we have the resources to take on the largest trucking corporations—and the local knowledge to understand what happened on that stretch of I-10 in Greenlee County. We know the difference between a blown tire caused by deferred maintenance and one caused by extreme heat. We know how to prove that a driver was fatigued after crossing three states, and we know how to get the settlement range you deserve—between $1.5 million and $9.5 million for catastrophic injuries, or whatever justice demands for your specific case.

Evidence is disappearing while you read this. The black box data that proves the driver was speeding. The maintenance records showing they knew the brakes were bad. The witness who saw the whole thing and is getting harder to find.
