Motorcycle Helmet Laws and Injury Claims

United States (federal and general)Last reviewed 18 September 2026

Helmet laws vary: as of April 2026, 17 states and D.C. require all riders to wear helmets, 30 states require them for some riders, and three states have no requirement. Not wearing a required helmet can be used to argue you share fault, which in most states reduces compensation rather than barring the claim.

What the Laws Require

Direct Answer: Universal helmet laws require every rider and passenger to wear a helmet, partial laws cover only certain riders such as minors or new riders, and three states have no requirement.

Which law applies depends on where the crash happened. Because helmet law data changes over time, check the current position for your state.

How It Affects a Claim

In most states a defendant can argue you were partly at fault for your injuries by not wearing a helmet, and your compensation is reduced by your percentage of fault, or barred in the few contributory negligence states, though the argument usually goes to the severity of head injuries rather than to who caused the crash. Some states limit or bar the use of helmet evidence, particularly where no helmet was legally required, so state law matters.

Protecting Your Claim

Keep your helmet, riding gear and the motorcycle, photograph the scene, and get medical care right away. Head and spinal injuries are the most serious outcomes in motorcycle crashes and often involve very high medical and long-term costs.

Frequently Asked Questions

Do all states require motorcycle helmets?

No. As of April 2026, 17 states and D.C. require all riders to wear helmets, 30 states require them for some riders, and Illinois, Iowa and New Hampshire have no requirement.

Can I still claim if I wasn't wearing a helmet?

Usually yes, but the defendant may argue comparative negligence and seek to reduce compensation, especially for head injuries. The rule varies by state.

Does helmet use affect who caused the crash?

Generally not. It is argued as affecting the severity of your injuries rather than causing the crash, though the effect on damages can be significant.

What if my state has no helmet law?

Some states restrict helmet evidence if no helmet was required, and others still allow it to be argued. It depends on state law and case law.

What should I keep after a motorcycle crash?

The helmet and gear, the motorcycle and photographs, along with medical records and witness details. Do not repair or dispose of the bike before it is inspected.

Can I get a motorcycle accident lawyer without paying upfront?

Usually, yes. Personal injury attorneys typically work on contingency, being paid a percentage of the recovery only if the case succeeds, with the percentage and the treatment of case costs set out in a written agreement. Ask whether costs are deducted before or after the fee is calculated, and read the agreement before you sign.
