Michigan motorists would have to allow 3 feet of clearance or a "safe distance" while passing a bike on the road under legislation moving toward the governor's desk.
The Michigan Senate on Tuesday gave final approval to the bills, which also require teen drivers to learn about laws pertaining to cyclists and other vulnerable roadway users as part of their initial driver education course.
Michigan is among 11 states with no "safe passing" law, and bicyclists have been lobbying lawmakers to act.
The 3-foot distance requirement would be in line with many other states. Motorists violating the new rules could face a civil infraction.
