Motorcycle Helmet Laws by State
The short answer
- Helmet requirements vary sharply: some jurisdictions cover every rider, some apply an age cutoff, and three have no statewide helmet requirement.
- Every row below comes from the same IIHS state-law table and was checked on July 30, 2026.
- A helmet-law cutoff does not erase separate eye-protection, passenger, equipment, insurance, or local requirements.

Motorcycle helmet law is not one national rule. States decide who must wear a helmet, and the result ranges from universal coverage to age-based requirements to no statewide mandate. This table compares all 50 states and Washington, D.C. on one verified basis.

Each row uses the Insurance Institute for Highway Safety motorcycle helmet-law table. The state link opens that state's free motorcycle permit practice test; the source link opens the law comparison used for the row.
What the age cutoffs mean
An age-based law applies to riders at or below the age shown in the table. It does not mean older riders face no safety or equipment rules. A state may separately regulate eye protection, passengers, insurance, approved helmet standards, or local riding conditions.
Why the state source still matters
The IIHS table makes the national comparison possible, but it is a summary of state law. Before riding, confirm the current rule with the state licensing or public-safety agency, especially if you are near an age cutoff or crossing a state line.

Why should you turn on your actual headlights, not just daytime running lights, during overcast or rainy daytime conditions?
- A. Daytime running lights usually don't light your taillights
- B. Daytime running lights already illuminate your taillights, so headlights add nothing
- C. Headlights are required only if you're driving faster than 45 mph
- D. It's purely a courtesy with no visibility benefit
Show answer
A. Daytime running lights usually don't light your taillights β Many daytime running light systems only power the front lights and skip the taillights to save energy, so in rain or overcast conditions, turning on full headlights ensures drivers behind you can see your taillights too.

Frequently asked questions
Do all states require motorcycle helmets?
No. Requirements vary by state. Some cover all riders, many use an age cutoff, and a small number have no statewide helmet mandate. The table above lists every state and Washington, D.C.
Does an age-based helmet law mean older riders need no protection?
No. It only describes the statewide helmet mandate. Eye protection, passenger equipment, insurance, approved-helmet, and local rules may still apply.
Does the law apply when riding through another state?
You must follow the law where you are riding. A trip across a state line can change the helmet requirement even when your motorcycle registration and license stay the same.
