When an 80,000-pound tractor-trailer loses control on the ice-slicked stretches of I-90 through Sweet Grass County, Montana, your life changes in an instant. These aren’t fender-benders. They’re catastrophic collisions that leave families shattered, medical bills mounting, and trucking companies scrambling to protect their profits.

At Attorney911, we’ve spent over 25 years fighting for victims of 18-wheeler accidents across America—including right here in Sweet Grass County. Ralph Manginello, our managing partner since 1998, has recovered multi-million dollar settlements for families just like yours. Our team includes Lupe Peña, a former insurance defense attorney who spent years inside the system watching adjusters minimize claims. Now he uses that insider knowledge to fight for you.

If you or someone you love has been injured in a trucking accident on Montana’s highways, call 1-888-ATTY-911 immediately. Evidence disappears fast, and the trucking company already has lawyers working to protect them.

Why Sweet Grass County 18-Wheeler Accidents Are Different

The Physics of Devastation

Your car weighs roughly 4,000 pounds. A fully loaded commercial truck barreling down I-90 toward Sweet Grass County outweighs you by twenty times—80,000 pounds of steel and cargo. The math is brutal: force equals mass times acceleration. When that much kinetic energy transfers to your vehicle, the results are catastrophic.

In Sweet Grass County’s rural stretches along the Yellowstone River valley, emergency services may be miles away. A collision on a remote section of I-90 between Big Timber and Livingston can leave you waiting for help while critical minutes tick by. That’s why these accidents so often result in traumatic brain injuries, spinal cord damage, and wrongful death.

Montana’s Unforgiving Terrain

Sweet Grass County sits at the crossroads of major freight corridors. Interstate 90—the primary east-west artery through Montana—sees heavy commercial traffic transporting goods between Seattle and the Midwest. Add in U.S. Highway 191 running north-south, and you’ve got a perfect storm of heavy trucks navigating challenging mountain terrain.

The dangers here are unique:

  • Mountain grades: Steep descents toward the Yellowstone River test brake systems
  • Weather extremes: Black ice in winter, sudden whiteouts, and high winds that can blow empty trailers off course
  • Wildlife corridors: Deer and elk crossings along I-90 cause evasive maneuvers that lead to jackknifes
  • Remote locations: Limited cell service means delayed emergency response

The 13 Types of Truck Accidents We See in Sweet Grass County

Jackknife Accidents on Icy Mountain Passes

When truck drivers brake suddenly on slick pavement near Deadman’s Basin or approaching the Crazy Mountains, trailers swing perpendicular to the cab. These jackknife accidents block multiple lanes of I-90, creating secondary collisions as passenger vehicles slide into the wreckage.

Why this matters for your case: Under 49 CFR § 392.6, drivers must reduce speed for weather conditions. If the driver was traveling too fast for icy roads, they’ve violated federal law—automatic negligence. We subpoena ECM data to prove exactly how fast they were going when they lost control.

Brake Failure on Steep Grades

The downhill stretch of I-90 west of Big Timber toward the Boulder River is notorious for runaway trucks. When brake systems fail due to poor maintenance, 80,000 pounds of truck becomes an unstoppable missile.

The regulation: 49 CFR § 393.40 requires properly functioning brake systems, and § 396.3 mandates systematic inspection and maintenance. If the trucking company deferred brake repairs to save money, they’re liable for every dime of your damages.

Underride Collisions—The Deadliest Crashes

When a car slides beneath a tractor-trailer, the roof of the passenger compartment often shears off. These underride accidents are almost always fatal. While federal law requires rear impact guards (49 CFR § 393.86), many trucks have inadequate protection, and side underride guards remain optional.

In Sweet Grass County’s winter conditions, reduced visibility from blowing snow can mask a stalled truck on I-90 until it’s too late. We investigate whether the trucking company maintained proper lighting and reflective tape—required by 49 CFR § 393.11.

Rear-End Collisions and the Stopping Distance Gap

A loaded truck traveling at 65 miles per hour needs nearly two football fields to stop—40% more distance than your car. On the long, straight stretches of Highway 191 north of Big Timber, distracted or fatigued truckers often fail to stop in time.

The violation: 49 CFR § 392.11 prohibits following too closely. When we download ECM data, we can prove the trucker was tailgating seconds before impact.

Wildlife-Induced Rollovers

When a truck swerves to avoid deer or elk on Sweet Grass County’s rural highways, the high center of gravity can cause rollover accidents. If cargo shifts improperly during the evasive maneuver, the truck becomes unbalanced.

Cargo securement rules: 49 CFR § 393.100 requires cargo to be immobilized to prevent shifting. Improperly secured loads are a leading cause of rollovers in Montana’s agricultural zones.

The 48-Hour Evidence Crisis

Here’s what most people don’t know: Electronic Control Module (ECM) data—the “black box” that records speed, braking, and engine performance—can be overwritten within 30 days. Electronic Logging Devices (ELD) that prove Hours of Service violations get deleted after six months. Dashcam footage often disappears within a week.

When you hire Attorney911, we send spoliation letters within 24 hours to trucking companies operating in Sweet Grass County. These legal notices demand preservation of:

  • ECM/Black box data (49 CFR § 395.8)
  • Driver Qualification Files (49 CFR § 391.51)
  • Maintenance records (49 CFR § 396.3)
  • Cell phone records
  • Dispatch communications

Wait too long, and the trucking company can legally destroy the evidence that proves they were negligent.

All 10 Liable Parties—Because We Dig Deeper Than Other Firms

Most law firms only sue the driver and the trucking company. That leaves millions of dollars on the table. Under Montana law, we investigate every potentially liable party to maximize your recovery:

1. The Driver
Speeding, distracted driving, or Hours of Service violations (49 CFR § 395) can prove direct negligence. ELD data reveals if they exceeded the 11-hour driving limit.

2. The Trucking Company (Motor Carrier)
Under Montana’s respondeat superior doctrine, employers are liable for their drivers’ negligence. Plus, we pursue direct negligence claims for negligent hiring (49 CFR § 391.11 requires qualified drivers), negligent training, and negligent supervision.

3. Cargo Owner/Shipper
Agricultural shippers in Sweet Grass County sometimes demand overloaded trucks to maximize profit. Overweight loads cause brake failures and rollovers.

4. Loading Companies
Third-party loaders who fail to secure cargo properly violate 49 CFR § 393.100, creating liability for cargo spill accidents.

5. Truck Manufacturers
Defective brake systems or inadequate stability control can trigger product liability claims against manufacturers like Freightliner or Peterbilt.

6. Parts Manufacturers
Defective tires or brake components often cause failures on Montana’s mountain grades.

7. Maintenance Companies
Third-party mechanics who perform negligent brake repairs or falsify inspection reports (49 CFR § 396.11) share liability.

8. Freight Brokers
Brokers who select carriers with poor safety records—ignoring FMCSA CSA scores—can be liable for negligent hiring.

9. Truck Owner (If Different from Carrier)
In owner-operator arrangements, the entity that owns the tractor may have separate insurance coverage.

10. Government Entities
Poor road design, inadequate signage for steep grades, or failure to maintain I-90 can implicate Montana DOT, though sovereign immunity limits apply.

Montana Law Specifics—What Sweet Grass County Victims Need to Know

The Clock Is Ticking—But You Have Three Years

Unlike Texas’s two-year deadline, Montana gives you three years from the date of your trucking accident to file a personal injury lawsuit. For wrongful death claims, you also have three years under Montana Code Ann. § 27-2-204.

But don’t wait. Three years sounds like a long time until you realize that black box data can be gone in 30 days, witnesses move away from Sweet Grass County, and trucking companies quietly settle with other victims to hide patterns of negligence.

Modified Comparative Negligence—The 51% Rule

Montana follows modified comparative negligence with a 51% bar (Mont. Code Ann. § 27-1-702). This means you can recover damages as long as you are 50% or less at fault. However, your recovery is reduced by your percentage of fault.

If you’re found 20% responsible for the accident (perhaps you were speeding slightly on I-90), you can still recover 80% of your damages. But if you’re 51% at fault, you recover nothing—even if the trucker was driving while fatigued in violation of federal law.

This makes evidence preservation critical. We need ECM data to prove the trucker was more at fault than you were.

Punitive Damage Caps in Montana

Montana limits punitive damages to the lesser of $10 million or 3% of the defendant’s net worth (Mont. Code Ann. § 27-1-220). While this seems high, trucking companies often structure themselves as LLCs with minimal assets. That’s why we pursue every liable party—we want multiple insurance policies, not just one pot of money.

Catastrophic Injuries—Your Life After the Crash

Traumatic Brain Injury (TBI)

When your head strikes the steering column or windshield, the brain collides with the inside of your skull. Symptoms may not appear for days: memory loss, personality changes, chronic headaches, and inability to concentrate. TBI victims often can’t return to their previous careers in Sweet Grass County’s ranching or agricultural sectors.

Settlement range: $1,548,000 – $9,838,000+ depending on severity and long-term care needs.

Spinal Cord Injury

A severed spinal cord means paralysis—paraplegia (loss of leg function) or quadriplegia (loss of all four limbs). The lifetime care costs can exceed $5 million, requiring home modifications in rural Sweet Grass County properties that were never designed for wheelchair access.

Amputation

When a truck’s underride guard fails or a vehicle is crushed, limbs may be traumatically amputated at the scene or require surgical removal later. Prosthetics cost $5,000–$50,000 each and need replacement every few years.

Settlement range: $1,945,000 – $8,630,000.

Wrongful Death

When a trucking accident kills a loved one on I-90 or Highway 191, surviving family members can recover:

  • Lost future income (critical for families in Sweet Grass County’s agricultural economy)
  • Loss of companionship and guidance
  • Mental anguish
  • Funeral expenses
  • Medical costs before death

Settlement range: $1,910,000 – $9,520,000+

The Attorney911 Advantage—Why Sweet Grass County Families Choose Us

Ralph Manginello’s 25+ Years of Federal Court Experience

Ralph Manginello has been fighting for injury victims since 1998. He’s admitted to the U.S. District Court, Southern District of Texas, which allows him to handle interstate trucking cases that cross state lines—crucial when Sweet Grass County accidents involve carriers from Texas, Washington, or elsewhere.

He was one of the few Texas attorneys involved in the BP Texas City explosion litigation, fighting against a Fortune 500 company after 15 workers were killed. That experience translates to taking on giant trucking companies like Walmart, FedEx, and Amazon that travel through Montana.

Lupe Peña’s Insurance Defense Insider Knowledge

Lupe Peña worked for a national insurance defense firm before joining Attorney911. He knows:

  • How adjusters use software (Colossus) to undervalue claims
  • The training manuals that teach adjusters to minimize payouts
  • When insurance companies are bluffing about their “final offer”

As client Donald Wilcox said: “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 $50+ Million Track Record

We’ve recovered over $50 million for families nationwide, including:

  • $5+ million for a traumatic brain injury victim (falling log case)
  • $3.8+ million for an amputation victim
  • $2.5+ million for truck crash victims

Currently, we’re litigating a $10 million hazing lawsuit against the University of Houston—proving we have the resources to take on institutional defendants with deep pockets.

4.9 Stars and “Family Treatment”

Our 251+ Google reviews average 4.9 stars. But don’t take our word for it. Chad Harris wrote: “You are NOT a pest to them and you are NOT just some client… You are FAMILY to them.”

Glenda Walker added: “They fought for me to get every dime I deserved.”

FMCSA Regulations That Prove Negligence

Federal law treats 18-wheelers differently than cars. These regulations, codified in 49 CFR Parts 390-399, establish strict safety standards. When trucking companies violate them, they’ve committed negligence per se:

Hours of Service (49 CFR Part 395)

  • Maximum 11 hours driving after 10 hours off-duty
  • Cannot drive beyond 14th consecutive hour on duty
  • 30-minute break required after 8 hours

Driver Qualifications (49 CFR Part 391)

  • Must have valid CDL
  • Pass medical exam every 2 years
  • Employer must verify 3-year driving history

Vehicle Maintenance (49 CFR Part 396)

  • Pre-trip inspections required
  • Brake systems must be properly adjusted
  • Annual inspections mandatory

Cargo Securement (49 CFR Part 393)

  • Tiedowns must withstand 0.8g deceleration forces
  • Periodic inspection during transport

When we prove violations, the trucking company is automatically liable under Montana negligence law.
