Truck Accident Claims: Who Is Liable and Why These Cases Are Different

Last reviewed: October 2026 · How we research: How We Research

A loaded tractor-trailer can weigh up to 80,000 pounds, roughly 20 times as much as a typical car. When a truck crash happens, the injuries are usually severe, and the claim that follows is very different from an ordinary car accident claim. There are federal safety rules, several companies that may share the blame, large insurance policies and evidence that can disappear quickly if nobody acts. This guide explains who can be liable after a truck accident, what makes these claims different, and what to look for in a lawyer.

Why truck accident claims are different

1. Federal safety rules apply. Interstate trucking companies and drivers must follow the Federal Motor Carrier Safety Regulations (FMCSRs), which cover driver hours, qualifications, drug and alcohol testing, vehicle inspection and maintenance, and cargo securement. A violation can be strong evidence of negligence.
2. More than one defendant. A car crash usually involves one driver and one insurer. A truck crash can involve the driver, the motor carrier, the owner of the trailer, a shipper, a maintenance contractor and a parts manufacturer, each with its own insurer and lawyers.
3. Higher insurance limits. Federal law requires interstate carriers of general freight to carry at least $750,000 in liability coverage, and $1 million to $5 million for oil and hazardous materials. Many carry more. That makes full compensation for serious injuries possible in a way that often isn’t with a car driver carrying state-minimum coverage.
4. Fast, organized defense. Trucking companies and their insurers often send investigators and lawyers to the scene within hours. The injured person needs someone working just as quickly.
5. Electronic evidence. Trucks generate data: electronic logging devices (ELDs) record driving hours, and engine control modules record speed, braking and throttle in the moments before a crash. This evidence can be decisive, but it isn’t kept forever.

Who can be liable for a truck accident

Freight brokers, who arrange loads between shippers and carriers, are sometimes sued for hiring an unsafe carrier. The law on broker liability is unsettled and differs between federal courts, so whether this is possible depends on where the case is brought. Owner-operators who lease their trucks to a larger carrier raise similar questions about who is responsible; the federal leasing rules and the “placard” on the truck’s door often point to the carrier.

The federal rules that matter most

• Hours of service. Property-carrying drivers may drive up to 11 hours after 10 consecutive hours off duty, can’t drive beyond the 14th hour after coming on duty, must take a 30-minute break after 8 hours of driving, and are limited to 60 or 70 on-duty hours over 7 or 8 days. Fatigue cases often turn on these records.
• Electronic logging devices. Most interstate drivers must record their hours on an ELD. Carriers must keep these records for six months, which is one reason early action matters.
• Drug and alcohol rules. Commercial drivers are prohibited from driving with a blood alcohol concentration of 0.04 or more, half the limit for most drivers. After certain crashes, carriers must test drivers for alcohol (within 8 hours) and drugs (within 32 hours).
• Driver qualifications. Carriers must keep a qualification file for each driver, including license, medical certificate, driving record and employment history.
• Inspection and maintenance. Drivers must inspect their vehicles and report defects, and carriers must systematically inspect, repair and maintain them and keep records.
• Cargo securement rules set how loads must be tied down and balanced.

You can look up a carrier’s safety record, inspection results and crash history using its USDOT number, printed on the truck’s door, in the FMCSA’s public Company Snapshot database.

What to do after a truck accident

1. Call 911 and get medical care. Truck crashes cause injuries, such as internal bleeding and brain injuries, that aren’t always obvious at first.
2. Photograph the truck, its USDOT number, company name, license plates of the cab and trailer, the scene and your injuries, if you can do so safely.
3. Get witness names and the police report number.
4. Don’t give a recorded statement to the trucking company’s insurer or sign anything before getting advice.
5. Act fast on evidence. A lawyer should send preservation letters to the carrier within days, covering ELD and engine data, dashcam video, inspection and maintenance records, and the driver’s file. The truck itself may need to be inspected before it is repaired.

Choosing a lawyer for a truck accident

Any personal injury lawyer can take a truck case, but these cases reward experience with federal trucking rules and the resources to fight several well-funded defendants. Questions worth asking at a free consultation:

• How many trucking cases have you handled, and how many went to trial?
• How quickly will you send preservation letters and inspect the truck?
• Do you work with accident reconstruction experts and specialists who can download truck data?
• Can you fund expert costs up front, and how are case costs handled if we lose?
• Who will actually work on my case day to day, and how often will I hear from you?

Most truck accident lawyers work on a contingency fee, typically around a third of the recovery and sometimes more if the case goes to trial. See how lawyer fees work and the contingency fee agreement explained.

What a truck accident claim can be worth

Because truck crashes so often cause serious injuries, such as spinal and brain injuries, multiple fractures, amputations and deaths, and because insurance limits are higher, truck claims frequently settle for much more than typical car accident claims. The value is built the same way: medical costs, lost income and earning capacity, and pain and suffering, reduced by any share of fault you carry. In wrongful death cases, the family’s losses are added. Try the car accident settlement calculator for a rough idea, keeping in mind that serious truck cases often need expert valuation.

Frequently asked questions

Can I sue the trucking company, or only the driver?

Usually both. Employers are generally responsible for their drivers’ negligence on the job, and carriers can also be directly liable for their own failures, such as hiring an unsafe driver or pushing unrealistic schedules. The company and its insurer are usually the main source of compensation.

What if the driver was an independent owner-operator?

The carrier whose authority the driver was operating under may still be responsible under federal leasing rules, even if it calls the driver an independent contractor. The name and USDOT number on the truck are the first clue.

Was I partly at fault for being in the truck’s blind spot?

Possibly, and insurers often argue this. But truck drivers have their own duties to check mirrors, signal and change lanes safely. In most states shared fault reduces compensation rather than eliminating it; in the few contributory negligence states it can bar a claim.

How long do truck accident cases take?

Often longer than car accident claims, because there are more parties, more records and usually more serious injuries. Many settle within one to two years; cases that go to trial can take longer. See how long injury claims take.
