Question: I have a question about pickups with their wide tires sticking outside of the fender wells: Is that illegal? I always thought there were supposed to be fenders? I know they throw a lot of rocks around. I don’t think that’s right.

Answer: Minnesota law states that all passenger vehicles shall have fenders, or other devices, that are designed to prevent, as far as practicable, water, dirt or other material being thrown up and to the rear by the wheels of the vehicle.

For the tires sticking outside of the fenders the vehicle would need to be equipped with fender flares. The fender flares would need to match the width of the tires sticking out.
