The rule
Bicycles are prohibited on Interstate highways in Alabama. 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.
What this means in practice
Stick to surface streets, US routes, state highways, and dedicated paths. If your route in Alabama appears to use an Interstate, plan a detour before you start.
