State has a Far Right as Practicable Requirement

Alabama requires a bicyclist on a roadway to ride as near the right side as practicable, while using due care when passing a standing or moving vehicle.

Allows Two Abreast Riding

Alabama allows bicyclists to ride two abreast on a roadway; the statute only prohibits riding more than two abreast, with an exception for bicycle-exclusive paths or roadway portions.

Single File is Required

Alabama has no single-file requirement. Riders may travel two abreast at any time on a roadway; the only restriction is on going beyond two abreast, which is limited to bicycle-exclusive facilities.

Has a Safe Passing Law

Alabama sets a specific three-foot minimum passing distance for motorists overtaking a bicyclist, but only on roadways with a marked bicycle lane, or on roadways without one where the speed limit is 45 mph or less and there is no double-yellow no-passing line — and only when the cyclist is riding within two feet of the right shoulder. Outside those conditions, only the general "safe distance" passing rule applies.

Helmets are required on the road

Riders and passengers under age 16 must wear a properly fitted, fastened bicycle helmet on any public roadway, bicycle path, public right-of-way, or public park. A parent or guardian who knowingly permits a violation is separately liable. Class 3 electric bicycles carry their own, broader helmet mandate covering all ages — see the e-bike restrictions entry.

If Bike Lanes are present, they are required ( except when unsafe )

Wherever a usable adjacent bicycle path has been provided, Alabama requires cyclists to use it and prohibits them from using the roadway instead.

Riders may use the sidewalks

Alabama's Title 32 defines a bicycle as a "vehicle" for purposes of the whole title, and separately prohibits driving "any vehicle" on a sidewalk except to cross a driveway. Read together, these two sections bar bicycle riding on sidewalks statewide, subject to the same driveway-crossing exception that applies to any vehicle. Local ordinances may be more permissive or more restrictive.

Does the Impeding Statute Apply to Bikes

Alabama's impeding-traffic statute applies by its own terms only to a "motor vehicle," and a non-electric bicycle is not a motor vehicle under Title 32's definitions. Bicyclists are given the general rights and duties of vehicle drivers under § 32-5A-260, but no bicycle-specific impeding provision was found, so applicability is situational at best.

Whether cyclists may treat stop signs as yield signs (the "Idaho stop").

Alabama has not adopted an Idaho-style "stop as yield" law for bicycles. Cyclists are given the same rights and duties as any other vehicle driver, including the duty to obey stop signs and traffic signals the same way a motorist must.

Restrictions exist on e-bikes and usage

Alabama gives electric bicycles the same rights and duties as ordinary bicycles and exempts them from driver's license, registration, title, and insurance requirements. E-bikes must carry a permanent label showing class, top assisted speed, and motor wattage, and may not be modified to change speed capability without relabeling. Local governments may, after notice and hearing, bar Class 1/2 or Class 3 e-bikes from bicycle or multi-use paths. Class 3 e-bikes additionally require a minimum operator age of 16 and helmets for all riders and passengers regardless of age.

Allows the concept of Contributory Negligence that allows any contributory fault resuls in 'no fault'

Alabama is one of a small number of jurisdictions (with Maryland, North Carolina, Virginia, and the District of Columbia) that retains pure contributory negligence: if a plaintiff's own negligence contributed at all to their injury, that bars recovery entirely, regardless of how much more at fault the other party was. The rule is common-law in origin; the Alabama Supreme Court reaffirmed it in Golden v. McCurry (1980) and left any change to the Legislature.
