Confirm equipment fit with the helmet size calculator before relying on an age rule alone.

Notes

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.

Statute

¹

A bell does not replace yielding or signaling, but it can warn other path users; compare bike bells and horns.

Penalty

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.

Statute

¹²

If alcohol or drugs may impair the rider, do not ride; arrange another way home and secure the parked bike with a lock suited to the theft risk.

Notes

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.
