Michigan's safety belt law allows police officers to stop a motorist solely for not wearing a safety belt in the front seat of a vehicle or if a child is not properly restrained, no matter where they are riding in a vehicle. The child passenger safety law covers children up through age fifteen (15). Children from birth through age three (3) must be in a child safety seat in the front and rear seats. As of July 1, 2008, children must be in a booster seat. until they are eight (8) years old or 4'9" tall no matter where they are riding in a vehicle. Children who are eight (8) years old but less than sixteen (16) years old riding in either the front or rear seat must use a safety belt.
