MN HF1832

Prohibits peace officers from stopping or detaining drivers for "mandatory secondary offenses" (vehicle registration, license plate illumination, muffler, noise limits, windshield violations, window restrictions, license plate validation stickers) unless conducting a separate moving violation stop or the vehicle is unoccupied.

Restricts stops for "presumptive secondary offenses" (unsafe equipment, headlamps, rear lamps, stop lamps, headlamp use, certain windshield violations) unless officer has reasonable suspicion and specific dangerous conditions exist, such as complete failure of headlamps, tail lamps, or stop lamps.

Allows officers to stop for presumptive secondary offenses creating a dangerous condition, imminent threat to human life, or complete lamp failure without requiring an unrelated moving violation.

Exempts commercial motor vehicles from all secondary offense restrictions.

Encourages law enforcement agencies to send warning letters to vehicle owners identified as having equipment violations when stops are not permitted.
