Helmet rules
Required under age
Required under age 16
Applies to passengers
Yes
Standard
ANSI Z90.4, Snell B-90 or ASTM F1447 (the statute predates the federal CPSC standard but a CPSC-certified helmet satisfies all three).
Penalty
Civil violation. Warning on a first offense; subsequent violations carry a fine of up to $50, but the court must waive the fine on proof that the rider has obtained a conforming helmet.
Alabama has no statewide statute that either authorises or prohibits riding on sidewalks. Cities and counties regulate sidewalk cycling under their general police power; Birmingham and Mobile prohibit it in central business districts, while Huntsville permits it outside marked downtown zones. Always check the local municipal code before riding on a sidewalk.
Alabama's DUI statute (Ala. Code § 32-5A-191) applies to anyone in actual physical control of a 'vehicle,' and § 32-5A-260 expressly grants bicyclists the rights and duties of vehicle operators. A bicycle DUI carries the same statutory penalties as an auto DUI — fines from $600 to $2,100 on a first offense, possible jail time, and a 90-day driver-licence suspension even though no motor vehicle was involved.
White lamp on the front, visible from a distance of at least 500 feet.
Rear requirement
Rear reflector or light
Rear spec
Red reflector on the rear visible from all distances from 100 to 600 feet when directly in front of lawful upper-beam headlamps. A red rear lamp visible from 500 feet may be used in addition to (but not in lieu of) the reflector.
Bicycles are prohibited on Interstates and other controlled-access highways in Alabama. Ala. Code § 32-5A-52 authorises ALDOT and local authorities to bar pedestrians, bicycles, and other slow-moving traffic from any controlled-access roadway by sign; ALDOT has exercised that authority on every Interstate corridor in the state.
