A reader submitted the following question: “Can you clarify what the speed limit is on a rural, unposted road? Is the speed limit lower on gravel roads?”

MCL 257.628 of the Michigan Vehicle Code sets the maximum speed limit at 55 miles per hour on all unposted highways.

Unpaved and gravel roads are included in that limit.

There is another statute referred to as the Basic Speed Law, MCL 257.627.

That law covers varying driving conditions and requires drivers to “drive at a careful and prudent speed not greater than nor less than is reasonable and proper, having due regard to the traffic, surface, and width of the highway and of any other condition then existing.”

That means that, on any road, gravel or paved, a driver can only drive at a speed that can be done so safely.

Gravel, wind, snow, and any other condition may reduce the maximum safe driving speed.
