At least seven U.S. states and 11 provinces/territories in Canada have spring and frost laws for roads. The seasonal restrictions limit traffic weight and speed on roads that have sub-bases affected by the spring warming. It’s time for truckers hauling in northern states to pay attention to the signs or risk a fine.
Michigan has four spring weight restrictions. All information on routes and dates are posted on the Michigan transportation website. Three of the restrictions in certain areas are already imposed. On March 8 another bulletin will be issued to lift weight restrictions from the southern Michigan border north to and including U.S. 12 at the Michigan/Indiana border east to Interstate 94 in Berrien County, then north and east to I-69 in Calhoun County, then north on I-69 to Lansing and continuing on I-69 east to Port Huron, St. Clair County. Frost restrictions are still in effect for the remainder of the state and will be imposed and enforced on all state trunkline highways north of the U.S. 12, I-94, I-69 line.
