Jackson County frost laws

Each spring, as the frost comes out of the ground, Jackson County’s road agency puts seasonal weight restrictions, often called frost laws, on county roads. While they are on, trucks carry less weight per axle on restricted roads and may be held to a lower speed. The agency decides when they start and end from the weather, so the dates change every year.

State highways in Jackson County (I-, US- and M- routes) are MDOT’s, and follow MDOT’s restrictions: see Michigan state highways (MDOT).

Below is the latest status ThawWatch has read from the agency, with the time the agency gave for it. ThawWatch can text you when it changes.
