Do you support mandatory headlight use in your area whenever it rains during the day?
As heavy rainfall moves across Minnesota, drivers are reminded that state law requires the use of vehicle headlamps and tail lamps during any form of precipitation. This safety mandate applies whenever it rains, snows, or hails, regardless of current visibility levels.
Why it matters
Using vehicle lights during inclement weather ensures your car remains visible to others on the road, reducing the risk of accidents caused by poor conditions. Following this state requirement also helps you avoid potential traffic citations during the current storm system.
Minnesota Statute 169.48 mandates lights during any precipitation, a requirement triggered whenever rain, snow, or sleet is falling. Current forecasts predict 1 to 2 inches of rain south of Interstate 94 and 2 to 4 inches near Interstate 90.
The players
Minnesota Department of Public Safety
The state agency responsible for vehicle safety regulations and public transportation enforcement.
The details
Drivers must manually activate their headlamps and tail lamps to comply with state law the moment precipitation begins. Visibility is also legally impaired if you cannot see vehicles or individuals 500 feet ahead. Beyond lighting, the Minnesota Department of Public Safety requires that you clear all snow and ice from your vehicle windows, hoods, and light lenses to ensure full visibility.

The Home Front
This mandate follows established traffic safety patterns enforced by Minnesota Statute 169.48 during inclement weather events. It reinforces a standard regulatory expectation that drivers must actively improve vehicle visibility when environmental conditions degrade.
Before heading out, check that your headlamps and tail lamps are fully functional and free of dirt or debris. If you are parked outside, make sure your car windows and lights are clear of any obstructions before you start your drive.
The takeaway
Always activate your vehicle lights as soon as rain begins to fall to comply with state requirements and improve safety. Keep a microfiber cloth in your glove box to quickly wipe off your lights and license plates if they become obscured by road spray or grime.
