Bike Laws in the US

What the law asks of people on bikes in the United States, topic by topic. There is no national bike code: each state writes its own rules and cities add more, so every page links to the statutes and tells you what to check locally.

TopicWhat the law says
HelmetNo federal or state law requires adults on regular bikes to wear one. 21 states and DC require helmets for minors, most often under 16, and some cities and counties go further.
Lights and reflectorsAt night: a white front light, typically visible from 500 ft (152 m), and a red rear reflector or light. New bikes are sold with front, rear, pedal and wheel reflectors (CPSC, 16 CFR 1512).
E-bike classesClass 1: pedal assist to 20 mph. Class 2: throttle to 20 mph. Class 3: pedal assist to 28 mph, riders 16+ with a helmet. All under 750 W, and treated like bikes: no license, registration or insurance.
Safe passing (for drivers)Most states require at least 3 ft (0.9 m) when passing a cyclist; New Jersey and Pennsylvania require 4 ft, and several states also require a full lane change when possible.
Lane positionRide with traffic, as far right as practicable when slower than traffic, except to pass, turn left, avoid hazards or when the lane is too narrow to share.
SidewalksOften allowed by state law with pedestrian rights and duties, but cities can ban it. In New York City it is illegal unless you are 12 or under on a small bike or a sign allows it.
AlcoholDepends on the state: California has a bike DUI offense (fine up to $250), Oregon applies its DUII law to cyclists, and Washington lets police impound an intoxicated rider’s bike.
Headphones and phonesCalifornia bans covering both ears; New York allows only one earphone. Phone bans are often written for motor vehicles, so check your state’s wording.
InsuranceNot required for regular bikes or Class 1 to 3 e-bikes. Homeowners and renters policies usually cover theft and liability, but may exclude e-bikes as self-propelled vehicles.
