NAFTA and Cross-Border Traffic

Note: Please check back frequently to ensure you have the most up-to-date information. Further implementation of NAFTA is currently under review.

Once fully implemented, the North American Free Trade Agreement (NAFTA) will impact cross-border traffic. It will allow Mexican commercial vehicles to travel in the United States if they meet all local, state and federal requirements. A moratorium, imposed by the U.S. Department of Transportation (USDOT), has been in effect since December 1995. When the cross border moratorium is lifted, this means that Mexican commercial vehicle operators will be able to travel in the United States.

Mexican vehicles that stay within the border commercial zones do not need additional registration. The Federal Motor Carrier Safety Administration (FMCSA) will issue operating authority for both border zone carriers and those that operate beyond the border.

If the Mexican commercial vehicle (truck, truck tractor, trailer, semitrailer, or passenger motor bus) stays within the designated commercial trade zone, additional Texas registration is not necessary. However, these vehicles are required to have current registration and valid license plates from Mexico to enter Texas.

Mexican vehicles also need to display the Secretaria de Comunicaciones y Transportes (SCT) windshield sticker and a USDOT permit to be legal. For information on the USDOT permit, call the Motor Carrier Division at (800) 299-1700, Option 8.

Once NAFTA is fully implemented, additional registration is required for Mexican motor carriers that travel beyond the commercial trade zones. Mexican vehicles, when traveling on Texas highways that go beyond the border commercial zones, are required to have one of three registration permits:

  • a NAFTA annual permit, issued by the Vehicle Titles and Registration Division (VTR), which is valid one year from month of issuance;
  • a 72-hour permit displayed on each vehicle; or
  • a 144-hour permit displayed on each vehicle.
