The Washtenaw County Road Commission imposed seasonal weight restrictions for trucks traveling on all-season roads this week.
For vehicles that weigh more than 10,000 pounds, there is a maximum speed limit of 35 miles per hour, regardless of the posted limit.
"Road damage caused by heavy vehicles during winter and spring thawing periods is a problem that affects all northern states," the commission wrote on its website.
"Speed, in conjunction with axle and wheel loading, contributes to road damage including the creation of potholes."
The restrictions went into effect on Feb. 25, and will remain in effect until further notice.
