Key Facts
- State level: As of July 2026, 17 states and the District of Columbia require helmets for all motorcycle riders, 30 states have partial requirements, and three states have no motorcycle helmet requirement.
- State level: Illinois, Iowa, and New Hampshire are the three states with no motorcycle helmet requirement.
- State level: A partial helmet law may depend on age, permit status, licensing history, insurance, safety-course completion, or whether the person is an operator or passenger.
- Federal and state: State law determines who must wear a helmet, while Federal Motor Vehicle Safety Standard No. 218 establishes performance requirements for motorcycle helmets manufactured for road use.
Motorcycle helmet laws are state laws, not one nationwide wearing rule. A rider crossing a state line can move from a universal requirement to an age-limited rule or to a state with no helmet mandate. The current national pattern therefore matters, but the operative text is always the law of the place where the motorcycle is being operated.
This guide uses the Insurance Institute for Highway Safety table updated in July 2026 as the principal 50-state and District of Columbia inventory, cross-checked against the Governors Highway Safety Association’s June 2026 summaries and selected current statutes.
States that require helmets for all motorcycle riders
Seventeen states require all operators and passengers covered by their motorcycle laws to wear helmets: Alabama, California, Georgia, Louisiana, Maryland, Massachusetts, Mississippi, Nevada, New Jersey, New York, North Carolina, Oregon, Tennessee, Vermont, Virginia, Washington, and West Virginia. The District of Columbia also has a universal requirement.
“Universal” describes the age reach of the requirement. Vehicle definitions and equipment specifications still matter, so a rule for motorcycles may treat mopeds, low-powered cycles, enclosed vehicles, or autocycles differently.
States with no motorcycle helmet requirement
Illinois, Iowa, and New Hampshire do not require motorcycle helmets. That classification does not mean a helmet lacks safety value or that every neighboring jurisdiction follows the same rule.
States with partial motorcycle helmet laws
The remaining 30 states use requirements that reach only specified riders or circumstances. The age below is the principal age threshold in the current IIHS table; additional conditions are noted where they materially expand the rule.
- Alaska: Riders age 17 and younger must wear helmets; the law also reaches passengers of any age and certain operators with permits.
- Arizona: Riders age 17 and younger must wear helmets.
- Arkansas: Riders age 20 and younger must wear helmets.
- Colorado: Operators and passengers age 17 and younger must wear helmets.
- Connecticut: Riders age 20 and younger must wear helmets.
- Delaware: Riders age 18 and younger and novice riders during their first two years must wear helmets; older riders must carry a helmet.
- Florida: The general helmet rule does not apply to a person over age 21 who has at least $10,000 in medical-benefits insurance for motorcycle-crash injuries.
- Hawaii: Riders age 17 and younger must wear helmets.
- Idaho: Riders age 17 and younger must wear helmets.
- Indiana: Riders age 17 and younger must wear helmets.
- Kansas: Riders age 17 and younger must wear helmets.
- Kentucky: Riders age 20 and younger must wear helmets, as must certain permit holders and newly licensed operators.
- Maine: Riders age 17 and younger must wear helmets, as must permit holders, operators during their first license year, and certain passengers.
- Michigan: Riders age 20 and younger must wear helmets; older riders may qualify for an exemption only when statutory experience or training and insurance conditions are met.
- Minnesota: Riders age 17 and younger and motorcycle-instruction-permit holders must wear helmets.
- Missouri: Riders age 25 and younger must wear helmets; a rider age 26 or older may ride without one only with the financial-responsibility and health-insurance qualifications stated by law.
- Montana: Riders age 17 and younger must wear helmets.
- Nebraska: Riders age 20 and younger must wear helmets; riders age 21 or older may qualify for an exemption through the licensing and safety-course routes specified by statute.
- New Mexico: Riders age 17 and younger must wear helmets.
- North Dakota: Riders age 17 and younger must wear helmets, and passenger coverage can depend on the operator’s age.
- Ohio: Riders age 17 and younger and operators during their first license year must wear helmets; related passenger rules also apply.
- Oklahoma: Riders age 17 and younger must wear helmets.
- Pennsylvania: Riders age 20 and younger must wear helmets; older riders generally need two years of motorcycle-licensing experience or an approved safety course to qualify for the exemption.
- Rhode Island: Riders age 20 and younger, all passengers, and operators during their first license year must wear helmets.
- South Carolina: Riders age 20 and younger must wear helmets.
- South Dakota: Riders age 17 and younger must wear helmets.
- Texas: Riders age 20 and younger must wear helmets; older riders may qualify for an exemption through approved training or qualifying health insurance.
- Utah: Riders age 20 and younger must wear helmets.
- Wisconsin: Riders age 17 and younger and motorcycle-instruction-permit holders must wear helmets.
- Wyoming: Riders age 17 and younger must wear helmets.
Why an age-only summary can be incomplete
Several partial-law states add rules for passengers, permit holders, newly licensed operators, or riders seeking an adult exemption. Florida illustrates an insurance-based exception: its statute exempts only a person over 21 who is covered by at least $10,000 in medical benefits for injuries from a motorcycle crash. Missouri instead uses an age-26 threshold together with financial-responsibility and health-insurance qualifications.
Nebraska shows how a recent amendment can make a short chart misleading. Its current statute allows a rider age 21 or older to ride without a helmet only through specified licensing and training routes, and it separately addresses passengers and eye protection.
Helmet construction standards are a separate federal layer
State wearing laws answer who must use a helmet. Federal Motor Vehicle Safety Standard No. 218, codified at 49 C.F.R. § 571.218, separately sets performance requirements for motorcycle helmets, including impact attenuation, penetration resistance, retention-system performance, and labeling.
A state may incorporate or reference approved-equipment standards in its own wearing law. The federal equipment standard does not turn the three no-law states into helmet-wearing states, and a state exemption does not change the federal manufacturing standard.
How to read a state helmet rule accurately
A useful reading starts with the rider’s age and then checks operator-versus-passenger status, permit or endorsement status, licensing history, safety-course completion, insurance conditions, and the statutory definition of the vehicle. Those details can determine whether the headline age threshold actually resolves the question.
Local enforcement provisions and penalties also differ. The state code and the responsible motor-vehicle or highway-safety agency are the best places to confirm the current rule before relying on a summary. For related context after a collision, see the guide to a motorcycle accident.
