According to Michigan Motor Vehicle Code Section 257, bicyclists may ride two abreast. “Two or more individuals operating bicycles upon a highway or street shall not ride more than 2 abreast except upon a path or portion of the highway or street set aside for use of bicycles.”
It is illegal to “pass between lanes of traffic” and to ride on limited-access highways (expressways). The Motor Vehicle Code does not prohibit sidewalk riding, however “an individual operating a bicycle upon a sidewalk or a pedestrian crosswalk shall yield the right-of-way to pedestrians and shall give an audible signal before overtaking and passing a pedestrian.”
Bicyclists do not have to use bike lanes even if present and do not have to wear helmets, although it is strongly recommended for safety to use bike lanes where provided and to wear head protection.
