Big Rig Accident Lawsuit: Evidence, Damages & Comparative Fault

A big rig accident lawsuit is a personal injury or wrongful death claim brought against a truck driver, the trucking company, and often several other parties after a collision with a tractor-trailer or 18-wheeler. These cases are not oversized car accident cases. They run on federal safety rules, they turn on electronic data that can vanish within weeks, and they involve insurance policies large enough to change what recovery looks like. Outcomes range from five-figure settlements for minor injuries to verdicts above $50 million in catastrophic and fatal crashes.¹

Who You Can Sue

The single biggest structural difference between a truck case and an ordinary car case is the number of possible defendants. A car crash usually has two drivers. A trucking case can have half a dozen parties, each on a different legal theory.

The truck driver. Personally liable for negligence such as speeding, distraction, fatigue, or impairment. Exceeding federal hours-of-service limits or falsifying logs can qualify as negligence per se.²
The trucking company. Held vicariously liable for its driver under respondeat superior, even when the driver is labeled an independent contractor. Courts look past the label to how much control the carrier actually had over the route, schedule, and equipment. The company also faces direct claims for negligent hiring, inadequate training, failure to supervise, and failure to maintain vehicles.³⁴
Freight brokers. Potentially liable for negligent selection when they hired a carrier with a known bad safety record or failed to verify federal compliance. The Ninth Circuit’s 2020 ruling in Miller v. C.H. Robinson Worldwide, Inc. confirmed these claims survive federal preemption under the FAAAA’s safety exception.⁵
Cargo loaders. Liable when improperly secured or overloaded cargo destabilized the truck, often proved through violations of federal securement standards in 49 CFR Part 393.³
Parts or vehicle manufacturers. Subject to strict product liability if brakes, tires, steering, or other components were defective.²
Maintenance contractors. Liable for faulty repairs or missed inspections that contributed to a mechanical failure.²
Government entities. May be liable for poorly maintained roads or inadequate signage. Claims against governments carry much shorter notice deadlines than ordinary claims.²

Federal leasing regulations at 49 CFR § 376.12 add another layer. When a carrier leases a truck it does not own, it must take “exclusive possession, control, and use” of that equipment for the lease term. Most courts read this as imposing absolute liability on the carrier for any crash involving the leased truck during the lease, whether or not the driver was technically an employee.⁶

Insurance follows the number of defendants. Interstate carriers hauling ordinary freight must carry at least $750,000 in liability coverage, and hazardous-materials carriers must carry up to $5 million. Many large fleets voluntarily carry $1 million or more.⁷³

How Long You Have To File

Every state sets its own deadline for filing personal injury and wrongful death lawsuits, and blowing it means the claim is gone regardless of how strong it was. Truck-crash deadlines generally run from one to six years, with most states clustered around two or three years from the date of the crash.⁸ Tennessee and Louisiana are on the short end at one year for many personal injury claims. Maine and Minnesota sit at the long end at six.⁹

Claims against government entities for road defects or inadequate signage are the trap door. Notice-of-claim windows are far shorter than the general statute; California requires notice within six months of the injury.⁹ The clock can be paused (tolled) when the victim is a minor, is mentally incapacitated, or when the defendant engaged in fraudulent concealment.⁸ When a crash crosses state lines, courts may apply choice-of-law analysis, and the safe assumption is that the shortest applicable deadline controls.

One point often missed: talking to the insurer does not pause the deadline. Negotiations continue until they don’t, and the statute keeps running the whole time.⁹

And even if your filing deadline is years out, the practical window to secure the electronic evidence from the truck is often weeks. That gap is why lawyers move on trucking cases fast.

The Evidence That Decides These Cases

The proof in a big rig case often sits inside the truck itself, on systems that don’t exist in a passenger vehicle. What that data shows, and whether it still exists by the time anyone asks for it, tends to decide who wins.

The Event Data Recorder

An Event Data Recorder, the truck’s “black box,” captures speed, braking, throttle position, seat belt status, and safety-system alerts in the seconds before and after a crash.¹⁰ Many EDRs automatically overwrite that data within 7 to 30 days of the crash.¹¹ Turning the ignition or moving the truck can trigger the overwrite. That short shelf life is the reason both sides sprint to the wreck.¹²

The Electronic Logging Device

The Electronic Logging Device records the driver’s on-duty, driving, and sleeper-berth hours, and is the source most often used to prove hours-of-service violations. Under 49 CFR 395.8(k), carriers must retain ELD records for at least six months, with a backup on a separate device. The data is recorded in real time; any edit must be annotated with the date, time, and identity of whoever made the change.¹⁰

Dashcam Footage

Federal law does not require dashcams, but many carriers install them. Front-facing cameras record the road and other vehicles; dual-facing cameras also record the driver, catching fatigue and distraction.¹³ The footage cuts both ways. In one Texas federal case, video showing a plaintiff merge into the front corner of a truck, contradicting the claim that the truck swerved, led to dismissal before discovery even began.¹⁴ A Florida federal court, on the other hand, rejected a carrier’s attempt to shield dashcam footage as attorney work product, holding it was material created in the regular course of business and therefore discoverable.¹⁵

The Spoliation Letter

Because trucking evidence is perishable, plaintiff attorneys typically send a spoliation letter to the carrier as soon as they’re retained. That letter creates a legal obligation to preserve ELD, EDR, dashcam, GPS, and maintenance records. If the carrier destroys or alters evidence after being put on notice, courts can sanction it, including by instructing the jury to assume the missing evidence would have hurt the carrier.¹⁶ If voluntary preservation fails, attorneys can seek emergency court orders.¹⁰

Carriers and their insurers often maintain rapid-response teams, including outside counsel and reconstructionists, on call around the clock. Their goal is to reach the scene the same day, photograph debris and skid marks before roads are cleared, and download electronic data before it overwrites.¹² If you wait weeks to call a lawyer, the defense side has already had those weeks.

Federal Safety Rules As Proof Of Negligence

The Federal Motor Carrier Safety Administration regulates commercial trucking under 49 CFR Parts 300–399, covering how long a driver can drive, how trucks must be maintained, who is qualified to drive them, and what insurance carriers must hold. Violating one of those rules can establish negligence per se: the violation itself proves the breach of duty, so the plaintiff does not have to separately show the defendant failed to act reasonably.⁷¹⁷

The rules that come up most in litigation:

Hours of service under 49 CFR 395. Property-carrying drivers are limited to 11 hours of driving inside a 14-hour work window, with a mandatory 30-minute break after 8 cumulative hours of driving.¹⁸
Driver qualifications. Carriers must verify commercial driver’s licenses, medical fitness, and driving records. Failing to vet a driver’s safety history is direct corporate negligence.¹⁷
Vehicle maintenance. Regulations require documented inspection and repair. Failing to fix known problems or to pull unsafe trucks out of service is direct evidence of negligence.¹⁷
Drug and alcohol testing. Carriers must run pre-employment, random, post-accident, and reasonable-suspicion testing.¹⁷

Federal record-retention windows track those rules. ELD and hours-of-service records must be kept for six months. Vehicle maintenance records must be kept for one year. Driver qualification files must be kept for three years after the driver leaves. Positive drug or alcohol tests must be kept for five years. Destroying records within those windows can trigger adverse-inference instructions at trial.¹⁷

How Your Own Fault Affects Recovery

What you recover depends on how the state treats shared fault, and the differences between states are large.

Five jurisdictions still follow contributory negligence: Alabama, Maryland, North Carolina, Virginia, and Washington, D.C. In these places, a plaintiff who is even 1% at fault recovers nothing. About a dozen states, including California, New York, and Louisiana, use pure comparative fault, letting a plaintiff recover damages reduced by their percentage of fault no matter how high that percentage is. Most states sit in between under modified comparative fault, cutting off recovery at 50% or 51% depending on the state. Texas and Georgia use a 50% bar. Pennsylvania, Florida, and Illinois use a 51% bar.¹⁹

A 2023 Georgia case shows the math. In Dalal v. Brown Trucking Company, a DeKalb County jury awarded $16.6 million to a 21-year-old plaintiff who suffered a traumatic brain injury after colliding with a Brown Trucking tractor-trailer stopped on I-285. The jury put 60% of the fault on the carrier and 40% on the plaintiff, cutting the effective award to roughly $10 million.²⁰²¹

What You Can Recover

Damages in a big rig case fall into three categories.

Economic damages cover quantifiable financial losses: past and future medical bills, lost wages and lost earning capacity, property damage, and in wrongful death cases, funeral costs and the financial support the deceased would have provided.²²

Non-economic damages cover subjective harm: physical pain and suffering, emotional distress, loss of enjoyment of life, and loss of consortium, meaning the deprivation of a family relationship’s benefits including companionship and affection.²²

Punitive damages are reserved for gross negligence, recklessness, or intentional misconduct, such as a drunk driver or a company that knowingly pushed drivers past federal rest limits. The U.S. Supreme Court has held that punitive damages generally should not exceed ten times the compensatory award.²²

There is no single average outcome. Injury severity, liability clarity, and available insurance drive the number. Broad estimates from 2025–2026 data:

Minor injuries such as whiplash and bruising: $10,000 to $50,000.²³
Moderate injuries with broken bones or surgery: $50,000 to $250,000.²³
Severe or permanent injuries such as traumatic brain or spinal cord injuries: $250,000 to $1 million or more.²³
Wrongful death: $500,000 to $5 million or more.²³

Cases with clear carrier negligence, catastrophic injuries, and deep insurance push much higher. A 2025 Los Angeles jury returned an $85 million wrongful death verdict after finding that a trucking company failed to maintain its vehicles and pushed drivers to violate hours-of-service rules. Many cases settle at policy limits. In California, an $8.4 million settlement for a spinal cord injury and a $100,000 settlement for a lane-change incident each hit the full available policy.²⁴

How The Lawsuit Moves Through Court

The stages are the standard civil litigation sequence, with trucking-specific twists.

It starts with a complaint. The plaintiff files a document identifying the defendants, describing the crash, stating legal theories (typically negligence and federal regulatory violations), and demanding damages. The case is usually filed in the state and county where the crash happened or where the trucking company has its principal place of business. After filing, the defendants are served and generally have 20 to 30 days to respond.²⁵

Then comes discovery. Both sides exchange information through depositions, interrogatories, and document requests. This phase alone typically adds at least six months to the timeline, and in trucking cases it is where the fight over ELD data, EDR downloads, dashcam files, maintenance records, and driver qualification files plays out.²⁵

Most cases settle. Negotiations often begin with a demand letter to the carrier’s insurer and can resolve at any point up through trial. Plaintiff attorneys typically work on contingency, commonly around 33% of the recovery, and take no fee if the case is lost.²⁵ When settlement fails, the case goes to a jury.

Where The Law Is Shifting

Two trends are worth knowing about because they change what plaintiffs can recover and how these cases are argued.

The Werner Reversal

On June 27, 2025, the Texas Supreme Court reversed a roughly $90 million verdict against Werner Enterprises. The 2014 crash underlying the case happened when a pickup lost control on an icy road, crossed a 42-foot median, and hit a Werner tractor-trailer in the oncoming lane. The jury had awarded $16.5 million to one plaintiff, $5 million to a second, and over $68 million to a third.²⁶

The Texas Supreme Court held that the Werner driver’s presence in his own lane at the moment of impact was a “happenstance of place and time” that furnished the condition for the crash but did not proximately cause it. The “sole substantial factor,” according to the court, was the other vehicle’s sudden loss of control and cross into oncoming traffic, all inside roughly two seconds.²⁶ Defense attorneys are already using the decision to argue that when an employee’s conduct did not proximately cause an injury, derivative claims against the employer for negligent hiring, training, and supervision must fall with it.²⁷

Damages Caps And Anchoring Bans

Several states have enacted trucking-focused tort reform as of mid-2026:

Iowa’s 2023 law caps non-economic damages in commercial vehicle cases at $5 million per plaintiff, with exceptions for impaired drivers and other egregious conduct.²⁸
West Virginia’s SB 583 (2024) applies a similar $5 million cap on non-economic damages in commercial vehicle cases.²⁹
Oklahoma’s SB 453 (May 2025) reinstated caps on non-economic damages at $500,000 for personal injury, rising to $1 million for permanent mental impairment, with no cap for permanent severe physical injury or cases involving recklessness or intentional harm.²⁸
Georgia’s SB 68 (April 2025) prohibits “arbitrary anchoring” in closing arguments, the tactic of suggesting specific dollar amounts for non-economic damages or referencing unrelated figures such as CEO salaries to prime the jury toward a high number.²⁸
Texas HB 19 (2021) targeted plaintiff trial tactics, and later appellate rulings tightened evidentiary requirements for pain-and-suffering awards.²⁹

None of these caps applies to economic damages, which in catastrophic-injury cases can reach tens of millions on their own.²⁹ The takeaway for anyone considering a claim: what state law applies matters as much as what happened on the road.
