TxDMV issues a single-trip permit for the transportation of portable buildings and portable building compatible cargo when exceeding Texas legal size limits. Single-trip permits may only be used for one movement, during the times specified on the permit, from a specific point of origin to a specific destination.
To qualify for the portable building single-trip permit, the vehicle and load must be no greater than 14 feet high and 80 feet long. Vehicles and/or loads exceeding these dimensions require a general single-trip permit.

TxDMV will check the number against the Federal Motor Carrier Safety Administration (FMCSA) system, MCMIS, for any out-of-service orders prior to permit issuance. The permit will be issued to the company name as it is listed for the USDOT Number.
