Alaska has no statewide bicycle-helmet law. The Municipality of Anchorage requires riders under 16 to wear a CPSC-certified helmet (Anchorage Mun. Code § 9.38.020); Juneau and Sitka have similar local ordinances. Adults are not required to wear a helmet anywhere in the state.
13 Alaska Administrative Code § 02.455 lets bicyclists use sidewalks unless prohibited by an official sign or local ordinance. A rider on a sidewalk has all the rights and duties of a pedestrian, must yield the right-of-way to pedestrians, and must give an audible signal before overtaking and passing. Anchorage and Juneau ban sidewalk riding in their downtown business districts.
Alaska's DUI statute (AS 28.35.030) applies only to operators of a 'motor vehicle, aircraft or watercraft,' and AS 28.90.990 excludes bicycles from the definition of motor vehicle. Cyclists impaired in public can still be charged with public intoxication or disorderly conduct, but the standard DUI penalties — including driver-licence revocation — do not attach to bicycle operation.

Alaska generally permits bicycle travel on the shoulders of state highways and Interstate-equivalent routes (the Glenn, Parks, Seward, and Richardson Highways) where no parallel alternative exists. Alaska DOT&PF posts site-specific 'No Bicycles' signs on bridges, tunnels, and certain urban segments around Anchorage; the on-ramp signage controls.
