Sidewalk riding

Statewide rule
Allowed with conditions
Notes
Michigan Compiled Laws § 257.660c expressly permits bicycles on sidewalks and crosswalks: a rider on a sidewalk has the rights and duties of a pedestrian, must yield the right-of-way to pedestrians, and must give an audible signal before overtaking. The statute does not apply where local authorities have prohibited bicycles on a particular sidewalk by official traffic-control device. Detroit, Grand Rapids, and Ann Arbor each restrict sidewalk riding in their central business districts via posted signs.

Applies to bicycles

BAC limit
Penalty
Michigan's OWI statute (MCL 257.625) applies to operators of a 'vehicle,' but the Vehicle Code's definition of vehicle (MCL 257.79) excludes 'devices exclusively moved by human power,' which leaves bicycles outside the statute. Cyclists may still face disorderly-person or public-intoxication charges under MCL 750.167.
