The 50-state motorcycle helmet law table
The table below summarizes each jurisdiction's motorcycle helmet requirement. "Universal" means every operator and passenger must wear a DOT-compliant helmet. "Partial" means only riders under the listed age (and sometimes novices) must wear one. "None" means no statewide requirement. Where a law is partial, riders above the age threshold may still need proof of insurance or a safety course in some states.

Why helmet laws matter
NHTSA estimates motorcycle helmets reduce the risk of death by about 37% for riders and 41% for passengers, and reduce head injury risk substantially in crashes. Universal-helmet-law states consistently show higher helmet-use rates and lower fatality rates than partial or no-law states. Even where the law allows riding without a helmet, a DOT-compliant helmet is the most effective single protection available.
Helmet compliance & eye protection
Where required, the helmet must meet FMVSS 218 and carry a DOT label — novelty helmets do not qualify. Note that roughly three dozen states also require eye protection (goggles, glasses, or a face shield) for operators, independent of the helmet rule. Crossing a state line means the new state's law applies immediately, so plan multi-state trips around the strictest requirement on your route.
Frequently Asked Questions
How many states require motorcycle helmets for all riders in 2026?
18 states plus the District of Columbia require helmets for every motorcycle operator and passenger regardless of age ("universal" laws). 30 states require helmets only for younger riders or novices ("partial"), and 3 states (Illinois, Iowa, New Hampshire) have no statewide motorcycle helmet law. Source: IIHS, May 2026 (retrieved 2026-08-11).
Which states have no motorcycle helmet law?
Only three states have no statewide motorcycle helmet law of any kind: Illinois, Iowa, and New Hampshire. In those states riders of any age may legally ride without a helmet on public roads, though local ordinances can differ and helmets are still strongly recommended.
What does a "partial" motorcycle helmet law mean?
A partial law requires helmets only for certain riders — usually those under a set age (commonly 17 or 20/21) or newly licensed riders. Older riders may ride without a helmet, though some states add conditions such as carrying minimum medical insurance (e.g., Florida, Texas) or completing a safety course. Always confirm your state statute.
Are passenger helmet rules the same as operator rules?
In universal-law states, yes — passengers must wear a helmet too. In many partial-law states passengers under the same age threshold must also wear one, and a few states (such as Pennsylvania and Rhode Island) apply extra rules to passengers or novice riders. Check the per-state table and your state DMV.
Does a DOT-approved helmet matter if the state requires one?
Yes. Where a helmet is required it must meet Federal Motor Vehicle Safety Standard (FMVSS) 218 and display a DOT certification label. Novelty helmets that lack the DOT label do not satisfy the law. A compliant, well-fitted helmet is the single most effective way to reduce head injury risk.
