You were rear-ended. The other driver was clearly at fault. And you were not wearing your seat belt. Does that change what you can recover? In New Jersey, it can, but not in the way most people fear, and the burden is on the defense to prove it.
The seat belt law
Under N.J.S.A. 39:3-76.2f, every driver and front-seat passenger must wear a properly adjusted and fastened seat belt. Rear-seat passengers 18 and older must also buckle up, though for adults in the rear it is a secondary offense. Drivers are responsible for passengers under 18. Children must be in child restraints or booster seats according to age, weight, and height under N.J.S.A. 39:3-76.2a.
Front-seat non-use is a primary offense: police may stop a vehicle for it alone. The fine is modest and no points are assessed. The larger cost is in the injury claim.
The seat belt defense: Waterson v. General Motors
In Waterson v. General Motors Corp., 111 N.J. 238 (1988), the New Jersey Supreme Court held that a plaintiff’s failure to wear a seat belt may be considered in reducing damages, under a specific framework:
- Non-use is not fault for the crash. The jury first determines who caused the collision and allocates fault for that under the ordinary 51% rule. Seat belt non-use plays no role at this step.
- The defense must prove the belt would have made a difference. Through expert testimony, usually biomechanical, the defense must show that the plaintiff’s injuries were caused or worsened by not wearing the belt.
- The jury apportions the injury. It determines what portion of the injuries are attributable to non-use (“second-collision” injuries) and what portion would have occurred anyway.
- Damages are reduced only for the non-use portion. And that reduction is further limited by comparing the plaintiff’s negligence in not buckling up to the defendant’s negligence in causing the crash.
The result: a plaintiff who would have been hurt regardless loses nothing. A plaintiff whose head went through the windshield because they were unbelted may see damages for that injury reduced, but only after the defense proves it with evidence, and only by a percentage.
What this means in practice
- The defense will ask about seat belt use in the recorded statement, interrogatories, and deposition. The police report often notes it.
- Expect a defense biomechanical expert in any serious injury case where non-use is documented.
- The argument is weakest for injuries a belt does not prevent (lower extremity fractures in a side impact, for example) and strongest for head, facial, and chest injuries in frontal crashes.
- Insurers often overstate the defense in settlement negotiations. It reduces the claim; it does not eliminate it.
Seat belts and PIP
Seat belt non-use has no effect on PIP. Your own carrier pays your medical bills regardless; see how New Jersey PIP works. The defense applies only to the claim against the at-fault driver.
Passengers
An unbelted passenger faces the same defense, and a driver who did not ensure a minor passenger was belted may face a separate negligence argument. Passengers’ claims otherwise run against the at-fault driver, whether that is their own driver, another driver, or both.
The same rule for motorcycle helmets
New Jersey courts apply the Waterson framework to helmet non-use in motorcycle cases; see the motorcycle helmet law and injury claims.

Frequently asked questions
Can I still get a settlement if I was not wearing a seat belt in NJ?
Yes. Non-use may reduce damages for injuries a belt would have prevented, if the defense proves that. It does not bar the claim.
Is not wearing a seat belt comparative negligence in New Jersey?
Not for causing the crash. It is considered only in apportioning damages for injuries attributable to non-use.
Does the seat belt law apply to back-seat passengers?
Yes. For adults in the rear it is a secondary offense; for minors, the driver is responsible.
Will the police report say whether I was wearing a seat belt?
Usually. The NJTR-1 has a safety equipment code for each occupant. See how to get your NJ crash report.
