Indiana Form M-233ST is a “Special Weight Single Trip Application” issued by the Indiana Department of Revenue. This permit is required for transport companies moving extra-heavy loads across specific state routes. It authorizes a single trip for vehicles that exceed standard weight limits but fall within the defined “special weight” maximums—specifically up to 134,000 pounds gross weight for most routes, or 90,000 pounds for others. The form legally validates the transport of commodities over a strictly defined network of highways, primarily in the industrial corridors of Northwest Indiana (such as Hammond, East Chicago, and Gary). It acts as a binding agreement where the driver and company attest that the vehicle’s dimensions and weights are accurate and that they will strictly adhere to the designated routes without unauthorized detours. The permit fee is listed as $42.50.
