Sooner or later in a lot of car accident claims, the adjuster asks the question. Were you wearing your seat belt? If the answer is no, many people assume the claim is finished. It usually is not. Whether that answer costs you anything depends almost entirely on the state where the crash happened, and the rules have been moving. We checked the statute or the controlling court decision for all 50 states and the District of Columbia in September 2026.
Not wearing a seat belt can reduce an injury settlement in 23 states. In 17 of them the jury can weigh it with no fixed limit, though several confine it to certain damages, and in 6 the law caps the cut, from 1% in Missouri to 25% in Iowa. 26 states and the District of Columbia keep the evidence out, so it cannot lower what you recover. Hawaii has no settled rule. The newest changes came in Indiana in 2024 and Georgia in 2025.
How the seat belt defense works
Crash lawyers talk about two collisions. The first is the car hitting the other car. The second is your body hitting the inside of your own car: the wheel, the windshield, the door. A seat belt does nothing to prevent the first collision, which is why not wearing one almost never makes you responsible for the crash itself. It can change the second collision a great deal.
The seat belt defense is the insurer's argument that some of your injuries came from that second collision and would have been smaller if you had been buckled in. Where a state allows it, the defense can use that argument to shave money off your damages. Where a state bars it, the jury never hears whether you were wearing a belt at all.

The six states with a fixed cap are the easiest to plan around, because the worst case is written into the statute:
| State | Most it can cut | How it applies |
|---|---|---|
| Missouri | 1% | Damages only, expert proof required |
| Michigan | 5% | Can count as negligence |
| Nebraska | 5% | Damages only, never liability |
| Oregon | 5% | Mitigation only |
| Wisconsin | 15% | Of the damages the non use caused |
| Iowa | 25% | Of damages after comparative fault |
