Seasonal Load and Speed Limits for Commercial Motor Carriers
The Antrim County Road Commission uses the Federal Highway Administration’s Guidelines for Spring Highway Use Restrictions to help predict the spring weight restriction period. The formula used depends on accurate air temperature forecasts so some judgement of its use is required. Please check this website often for updates on spring weight restrictions.
Seasonal weight and speed reductions may be enforced during the spring of each year on county roads. Maximum axle loads shall be reduced by 35 percent and shall not exceed 450 pounds per inch of tire width. Travel speed limit is 35 MPH during seasonal restrictions.
