[ARCHIVED] Berrien County Frost Laws

Frost Restrictions

Berrien County along with other Southwestern Michigan counties are activating annual frost laws to protect roads. Enacting Frost Laws in the Spring helps preserve the condition of the roadway. Road surfaces can crack and develop stress fractures in reaction to too much weight being placed upon the surfacing during this time. The length that frost laws are in effect is determined based upon weather conditions.

When conditions justify the need for frost laws, the Michigan Department of Transportation (MDOT) and county road agencies enact weight restrictions on roadways that are not designated as all-season routes. Additional details of seasonal restrictions can be found in Section 257.722 of the Michigan Vehicle Code, Act 300 of 1949. There are a few exemptions allowed for those hauling agricultural commodities and public utility vehicles.

The County Road Association of Michigan online provides an update of current weight restrictions in each county across the state of Michigan. For the most up-to-date information on weight restrictions on state roads, visit Michigan Department of Transportation (MDOT)

Following frost laws help maintain and protect roads from greater deterioration during this weather shift.
