13 Axle South Dakota A-Train

semi truck tractor trailer While there is a lot of media attention on the heavy weights available in Michigan, South Dakota has no gross weight limit and no limit on the number of axles on its combinations. Additionally, combinations can operate with a cargo-carrying limit of 81’6”, which usually translates into a couple of 40’ trailers being utilized with numerous axles mainly for agricultural goods. The combination must comply with the bridge formula and be licensed and permitted for the high weight.
