For a five axle tractor-trailer combination with at least a 35 foot bridge between the trailer and drive axles, Tennessee follows the federal Interstate weight limit of 80,000 lbs. before a permit is required. With a permit, a five axle unit can gross up to 105,000 lbs., but will be restricted to secondary roads. Straight trucks tend to be a bit more complicated. For a tandem axle truck, 54,000 lbs. on secondary roads is the norm, but it may not be allowed to gross as much on the Interstate Highways if it has insufficient wheelbase.
