Watch for spring weight restrictions
Posted February 16, 2017
With unseasonably warm temperatures in many Northern Tier States, it is important for the commercial driver to be aware of annual spring weight restrictions. Some begin as early as February and many last into May.
Seasonal weight restrictions may change from year to year based on the weather. Typically, effective dates are set by states based on:
- Frost depths measured along state highways,
- Observed road conditions, and
- Weather forecasts.
Motor carriers and their drivers need to monitor state websites for effective dates and affected highways. In addition, drivers need to watch for road signs indicating seasonal weight restrictions.
Once a state feels its roads have regained stability, it will remove the weight restrictions. This occurs when the frost line is deep enough to allow moisture to escape.
An example of an exceptionally early weight restriction is Michigan. Michigan Department of Transportation (MDOT) and local agencies enacted measures to protect state roadways effective February 10, 2017. For Michigan highways affected by the mandate, see the MDOT website.
