Multi-State (WASHTO) Single-Trip Permits

Multi-State Single-Trip Permits are issued under the Western Regional Permitting Agreement ("WASHTO"). The State of Texas, through TxDOT, participates in the "Western Regional Agreement for the Issuance of Permits for Oversize and Overweight Vehicles Involved in Interstate Travel." Under the terms of the agreement, each member state may issue regional permits allowing operations in any other member state. The following states are currently members of the Western Regional Agreement: Arizona, Idaho, Montana, Oregon, Utah, Washington, Texas, New Mexico, Colorado, and Oklahoma, Louisiana, Nevada.

How Do I Apply?

When applying through TxDOT, customers may use Online Permits (CPS) to apply for and receive a permit, submit a completed Form 400, Western Regional Permit Application [pdf, 1 page, 29kb] by fax (512) 465-3549, or call (800) 299-1700 to order by phone. Call (800) 299-1700, options 1 then 2, if you have any questions.

Applications submitted to Texas by fax must include credit card payment, Permit Account Card, or escrow information.

NOTE: Movement of manufactured homes is not covered under the Western Regional Agreement due to the numerous variances between jurisdictions.

Permittees under the Western Regional Agreement must fall within the non-reducible maximum dimensions listed below:

Weight - 14’

• 600 pounds per inch of tire width
• 21,500 pounds per axle
• 43,000 pounds per tandem axle
• 53,000 pounds per tridem (wheelbase more than 8’ and less than 13’)
• 160,000 pounds gross weight
• In no case may the gross weight exceed the sum of the permitted axle, group axle weights or the weight specified by the permit, whichever is less.
• A minimum of five axles
• The weight on any group of axles shall be determined by the permissible weight table.

Length - 14’

• 110’ overall. This agreement does not authorize permits for a semitrailer longer than 53’ to carry more than one item, or for any unladen semitrailer longer than 53’ used in a truck-tractor and semitrailer combination.
• In Oregon, an unladen combination of vehicles may consist of the towing or power unit and not more than one "jeep," one semitrailer and one "booster," provided semitrailer length is not more than 62’. Movement is authorized unladen with fewer vehicles, or with the jeep and/or booster loaded on the semitrailer. However, the absence of both the jeep and the booster (carried as load or in use) invalidates this provision.

It is the company’s responsibility to have proper vehicle registration or to acquire the proper registration in each state that the load will travel.

In Texas, carriers must provide a Federal Highway Administration (FHWA), a Texas Motor Carrier Registration number, or have a Superheavy or Oversize Permit Bond on file.

This single-trip permit is valid for a period of five working days, for use by the permitted vehicle only (tractor or trailer). Permits may not be issued more than five calendar days in advance of the effective date. One extension of up to five days may be granted, provided the permittee can show that weather, road conditions, or a mechanical failure of the vehicle precluded completion of the permitted trip during the initial five-day period.
