Michigan Compiled Laws, Chapter 257. Motor Vehicles § 257.715

Sec. 715. (1) Equipment on motor vehicles as required under this act shall be maintained as provided in this act. A uniformed police officer may on reasonable grounds shown stop a motor vehicle to inspect the vehicle, and if any defects in equipment are found, issue an appropriate citation under section 728 or 742  1 to the driver and order the driver to have the defect or defects repaired immediately. In case of an accident a police officer may make an inspection of the vehicles involved in the accident.

(2) The director of the department of state police shall cause inspection to be made of motor vehicles operating on the public highways to detect defective equipment or other violations of law governing the use of public highways by motor vehicles, operators, and chauffeurs. For that purpose the director may establish temporary vehicle check lanes at appropriate locations throughout the state for checking for inadequacies and violations. A county, city, village, or township police department also may operate a temporary check lane within its limits with the express authorization of the director of the department of state police and under the direct supervision of a designated representative of the director.
