How are speed limits determined on county roads?
A common misconception is that the Road Commission has the authority to install speed limit signs at its discretion. Before a speed limit sign can be posted, a joint speed study must be conducted involving the Michigan State Police and the Road Commission. As of November 9, 2006, a new prima fascie law was adopted allowing speed limits to be set according to road type and access points. An engineering study may still be required.
