Key Responsibility

The Oversize & Overweight Permit Office of the Tennessee Department of Transportation is responsible for prescribing rules in the interest of public safety and preservation of highways, for the issuance and or renewal of special permits for the transportation of such oversize, overweight, or over-length articles or commodities as cannot be reasonably dismantled or conveniently transported otherwise, and for the operation of such super-heavy or overweight vehicles, motor trucks, semi-trailers and trailers, whose gross weight, including load, weight, height or length, may exceed statutory limits, or which in other respects fail to comply with requirements of the Tennessee Code Annotated, as may be reasonably necessary for the transportation of such oversize, overweight or over length articles or commodities as cannot be reasonably dismantled or conveniently transported otherwise.
