Who Is Liable in a Car Crash?

Most car crash claims start with the other driver, but the driver is not always the only party who may be responsible. An employer, the vehicle owner, a government agency or a parts maker can also play a role. Identifying every party with legal responsibility is an early task for a car accident lawyer, since each responsible party may carry its own insurance.
Driver negligence
A negligence claim asks whether a driver failed to use reasonable care. Typical examples include distracted driving, speeding, impaired driving, following too closely and failing to yield. In many states, a traffic law violation can serve as evidence of negligence, and some states apply negligence per se. A traffic citation helps a claim, but it is not required to prove fault, and paying a ticket is treated differently from state to state. A car accident attorney will measure the driver's conduct against the traffic laws where the crash happened.
Owners and rental companies
When the driver borrowed the car, the owner's policy often covers permissive users. The owner may also face a negligent entrustment claim for lending a car to someone known to be unlicensed, impaired or unsafe. Rental and leasing companies are treated differently. Under a federal law called the Graves Amendment, they are generally shielded from liability for a renter's negligence, unless the company was negligent itself, for example by renting out a car with a known brake defect.
Drivers on the job
If the driver was acting within the scope of employment, the employer is usually answerable for the driver's negligence under respondeat superior. This can cover delivery drivers, sales staff and others who drive as part of the job. Rideshare crashes raise separate coverage questions, since the available coverage can depend on whether the app was on and a ride had been accepted. A car accident lawyer will typically request the employer's policy in addition to the driver's.
Government agencies and manufacturers
A broken traffic signal, a missing stop sign or a dangerous road defect may involve a government agency. Claims against public bodies come with special immunity rules and short notice deadlines, and those rules vary by state. If a defective tire, brake or airbag contributed to the crash or the injuries, the manufacturer may face a product liability claim. Open recalls can be checked with the vehicle identification number on the NHTSA recall lookup. In some states, a bar that served a visibly intoxicated driver may face a dram shop claim.
When a passenger is hurt
A passenger hurt in a crash may have claims against either driver or both, even the driver of their own vehicle. Coverage can come from the policy on the car the passenger rode in and from the other driver's policy, and in some cases from the passenger's own policy. Certain policies restrict claims between relatives who live in the same household, which makes the wording of the policy important.
How shared fault affects the claim
Most states use comparative negligence, which may reduce a recovery by the injured person's percentage of fault, while a small number still apply contributory negligence. States also differ in how fault is divided among several defendants. An automobile accident lawyer looks at every possible party because one policy may not cover the full loss. This is general information and not legal advice, and no outcome can be predicted from it.
