Winter safety

Snow, sleet, ice, and freezing temperatures all have an effect on winter driving conditions. This may mean driving slower than the posted speed limit, leaving more distance between your vehicle and the one in front of you, allowing extra time to arrive at your destination, and checking road conditions before leaving.

Remember: Ice and snow, take it slow.

Winter driving legislation

Public Act 300 Section 257.627 - Motorists must follow Michigan's Basic Speed Law, which requires them to drive at a "careful and prudent" speed in all conditions. 

Public Act 300 Section 257.643b - Motorists are required to stay at least 200 feet, or about the length of 12 cars, when following a snowplow. This does not apply when legally passing a snowplow. When a motorist approaches a snowplow from the rear that is stopped at or in an intersection, they shall stop not less than 20 feet from the snowplow.
