My drive into work this morning was a nasty one.

While Highway 10 between Monticello and St. Cloud was clear enough to comfortably drive the speed limit, loose snow on the road blown up by vehicles ahead of me slowed my drive as conditions seemed more like a blizzard. Light fog made it even harder to see.

By about Becker, I noticed that a lot of cars' headlights weren't on. I also realized mine weren't, either. Technically, I was guilty of a traffic violation.

Minnesota law requires drivers turn their lights on both when it's snowing and when visibility is impaired by snow.

169.48 VEHICLE LIGHTING.

Subdivision 1.Lights to be displayed.

(a) Every vehicle upon a highway within this state:

(1) at any time from sunset to sunrise;

(2) at any time when it is raining, snowing, sleeting, or hailing; and

(3) at any other time when visibility is impaired by weather, smoke, fog or other conditions or there is not sufficient light to render clearly discernible persons and vehicles on the highway at a distance of 500 feet ahead"

A violation will run you a $115 ticket.
