MN HF4922

Creates two categories of vehicle equipment violations: "mandatory secondary offenses" (11 violations including expired registration, missing muffler, broken wipers) and "presumptive secondary offenses" (unsafe vehicle condition, single functioning light, cracked windshield).

Prohibits peace officers from stopping or detaining drivers for mandatory secondary offenses unless the officer lawfully stopped them for an unrelated moving violation or the vehicle is unoccupied.

Prohibits peace officers from stopping or detaining drivers for presumptive secondary offenses unless lawfully stopped for an unrelated moving violation, the vehicle is unoccupied, or the violation creates a substantial, identifiable risk to human life or imminent safety hazard.

Requires officers to state the reason for any traffic stop, document the reason on citations or reports, and conclude stops within 25 minutes; exempts officers when withholding the reason is necessary to protect life or property from imminent harm.

Allows law enforcement agencies to send warning letters to vehicle owners for equipment violations when officers lack grounds to stop the vehicle; exempts commercial motor vehicles from these restrictions.
