General Single-Trip

A commercial motor vehicle includes any motor vehicle or combination of vehicles with a gross weight, registered weight, or gross weight rating in excess of 26,000 pounds that is designed or used for the transportation of cargo in furtherance of any commercial enterprise.

Vehicles or loads exceeding 80,000 pounds will also pay a highway maintenance fee in addition to the above permit fee. Highway maintenance fees are listed in the table below.

For loads with a tractor and trailer combined gross vehicle weight (GVW) exceeding 200,000 pounds, total axle spacing must exceed 95 feet. Single-trip permits are also available for the movement of vehicles and loads that exceed 254,300 pounds total gross weight, or exceed the maximum permittable weight on any axle or axle group, or exceed 200,000 pounds with less than 95 feet of axle spacing. A vehicle supervision fee will be charged in addition to the permit and highway maintenance fees. An application for a permit requiring an engineering analysis must be accompanied by the vehicle supervision fee and a copy of the contract for transport. See sport. See Super Heavy Single-Trip Permits for additional information or contact the Motor Carrier Division at (800) 299-1700.

A permit fee will not be refunded after the permit number has been issued unless such refund is necessary to correct an error made by the Motor Carrier Division.

• Identification and location of the transporting company and the company contracting the transport
• Description of what's being transported and its weight
• Origin and destination of the transported load
• Identification of the date(s) in which the load will be transported

TxDOT has a process for accommodating repeated movement of equipment, such as construction equipment or any load that is uniquely identified. For example, after we have collected the information on a piece of equipment that you move on a regular basis, such as a 345 Cat Excavator, we will enter the description into an internal file and use the information each time you move this load. The description will be on the permit and the Department of Public Safety will verify that it does in fact match the load you are transporting. For loads that are not uniquely identified, such as vessels, generators, boilers, and transformers you will be required to submit weight information each time you transport the load.

See general escort requirements and equipment requirements for both permitted vehicles and escort vehicles.

Law enforcement assistance may be required by the MCD to control traffic when a permitted vehicle is being moved within the corporate limits of a city, or at such times when law enforcement assistance would provide for the safe movement of the permitted vehicle and for the traveling public's safety.

It is the responsibility of the permit holder to contact utility companies, telephone companies, television cable companies, or other entities when it is necessary to raise or lower an overhead wire, traffic signal, street light, cable, sign, or other overhead obstruction. The permit holder is responsible for providing the advance notice and coordination required by each entity.
