How car accident claims work
Most car accident claims are about negligence, meaning someone failed to drive with reasonable care, for example by speeding, texting, running a light or driving impaired. The person harmed can ask the at-fault driver's insurance to pay for losses such as medical bills, lost wages, vehicle damage, and pain and suffering. Lawyers call these losses damages: economic damages are measurable costs, and non-economic damages cover things like pain and lost quality of life.
Many claims are settled with insurance companies without a trial. A lawsuit is usually filed only when a fair settlement cannot be reached, or when a filing deadline is approaching.
Who may be affected
Drivers, passengers, pedestrians, cyclists and motorcyclists can all have claims. Family members may have a wrongful death claim when a crash is fatal. Sometimes more than one party shares responsibility, such as a trucking company, a vehicle or parts maker, or a government agency responsible for a dangerous road. When the at-fault driver has no insurance or flees the scene, your own uninsured motorist coverage, if you have it, may help.
Injuries, insurance and fault rules
Crash injuries range from whiplash and broken bones to brain and spinal cord injuries. Some, like concussions, may not cause symptoms right away, so prompt medical care matters for your health and for your records. Insurance and fault rules differ by state:
- No-fault states: 12 states and Puerto Rico use no-fault insurance. Your own personal injury protection (PIP) pays medical bills and lost wages regardless of fault, and lawsuits for pain and suffering are limited to more serious injuries.
- Fault states: in the rest, the at-fault driver's insurance generally pays.
- Shared fault: most states reduce compensation by the injured person's share of blame, and many bar recovery above a set percentage. Alabama, Maryland, North Carolina, Virginia and Washington, D.C. can bar recovery for someone who was even slightly at fault.
Where things stand (as of October 2026)
Federal safety officials estimate that 36,640 people died in U.S. motor vehicle crashes in 2025, down 6.7 percent from 2024 and back to levels last seen before the pandemic. Those are early estimates; final figures come later.
Insurance requirements and fault rules are set by state legislatures and change from time to time, so check the current rules in the state where the crash happened.
Deadlines and what to gather
Every state has a statute of limitations for injury lawsuits, and the length differs by state. Claims against a city, county or state agency often require a written notice within a much shorter time. Your own insurance policy also requires prompt notice of a crash.
- The police or crash report number
- Photos of the vehicles, the scene, road conditions and your injuries
- Names, phone numbers and insurance details of everyone involved, plus witnesses
- Medical records, bills and receipts
- Proof of missed work and lost pay
- All letters and emails from insurance companies
Talking to a lawyer
A licensed attorney who handles car accident cases can deal with insurers, estimate what a claim may be worth and explain your state's deadlines and fault rules. It is wise to talk to one before giving a recorded statement or signing a release. Your state bar's lawyer referral service can help you find one.
Most car accident lawyers work on a contingency fee: a percentage of any recovery, set out in a written agreement, usually with no fee for their time if nothing is recovered. Ask about the percentage, how costs are paid and whether the rate rises if the case goes to trial. Bring the crash report number, photos and medical records to a first meeting.
