After a truck accident you may be able to sue more than the driver. Depending on what caused the crash, the trucking company, a freight broker, the shipper or loader, a maintenance shop, a parts manufacturer, the trailer owner, a government agency, or another motorist can share liability. Answer the eight questions below and the checker lists every party that fits your crash, plus the evidence that proves each one.
1 party may share liability · 8 questions left to refine
- The truck driverPossible
Drivers are personally responsible for unsafe driving: speeding, following too close, distraction, fatigue, or impairment.
Evidence that proves it: Police report, ELD hours-of-service logs, phone records, drug/alcohol test results.
General information based on your answers, not legal advice. Liability depends on the facts and on the law of the state where the crash happened.
Why truck crashes have more defendants than car crashes
In a car wreck there is usually one driver and one insurer. A tractor-trailer is a business operation: one company may employ the driver, another may own the trailer, a third arranged the load, and a fourth loaded it. Each made decisions that can lead to a crash, and each may carry its own insurance. That is why an 18-wheeler accident lawyer investigates the whole chain instead of stopping at the driver.
The parties the checker looks for
The driver and the trucking company
The driver is responsible for how the truck was driven. The motor carrier is usually responsible for the driver on the job, and can be directly liable for hiring an unqualified driver or pushing schedules that break hours-of-service limits. Federal rules define the employer to include carriers that lease owner-operators (49 CFR § 390.5).
The shipper or loader
Loads must be properly distributed and secured (49 CFR § 392.9). When freight shifts, it can cause cargo-shift crashes, rollovers, and jackknifes, and the company that loaded it may share fault.
Maintenance shops and manufacturers
Carriers must systematically inspect and repair their trucks (49 CFR Part 396). If an outside shop did the work badly, or a part was defective, the shop or the manufacturer can be liable. Typical examples are brake failure and tire blowouts. Keep the failed part; it is the evidence.
Freight brokers
Brokers match loads with carriers. Victims have sued brokers for picking carriers with bad safety records, but courts are split on whether federal law (49 U.S.C. § 14501) preempts those claims. The checker marks brokers as “possible” for that reason.
Equipment owners, government, and other drivers
A leasing company is not liable just for owning the trailer (the Graves Amendment, 49 U.S.C. § 30106), but it is liable for its own negligence. A road agency can be liable for a dangerous work zone, though notice deadlines for government claims are often far shorter than the normal statute of limitations. Other motorists who set off the crash can share fault too, which matters in states with comparative negligence rules.
What to do with your results
Every party on your list has records that can be lost: dashcam footage is often overwritten in days, and electronic logs and black box data have limited retention. An attorney can send preservation letters to each defendant right away. More defendants can also mean more insurance, which matters when one policy limit won't cover serious injuries. Check your timeline with the filing deadline calculator, and read what to do after a truck accident for the first steps.
How this checker works
Each answer maps to the parties commonly examined in commercial truck cases under the federal rules cited below. “Likely” means the fact you reported is a standard basis for liability; “possible” means it depends on details the tool can't know, or you answered “not sure.” Nothing you enter is stored or sent anywhere. This is general information, not legal advice.
