Federal Disaster Declaration Relief Permit

Carriers may be eligible for use of a relief permit for moving an overweight load in areas of Texas impacted by recent flooding (does not apply to oversize loads) to:

  • Deliver a load that consists entirely of relief supplies. Relief supplies include but are not limited to medicine, medical equipment, food supplies (including for livestock), water, and materials for building temporary structures, or
  • Transport materials away from the disaster area, such as debris, in order to facilitate the delivery of relief supplies, provided the removal expedites the clearing of roadways, staging areas, or locations for temporary structures to facilitate delivery of relief supplies.

If your operation meets these criteria, you may obtain a Federal Disaster Relief Permit through the Texas Permitting and Routing Optimization System TxPROS). https://txpros.txdmv.gov/.

The permit is not valid for loads leaving the area except for those removing debris.

A copy of the President’s federal disaster declaration must be carried with the permit. The declaration can be found here: https://www.fema.gov/press-release/20250706/president-donald-j-trump-approves-major-disaster-declaration-texas.

The Federal Disaster Relief Permit allows travel on all state and federal roads, including the interstate highway system. The permit may not be used for overwidth, overlength, or overheight loads.

See permit for a complete list of movement conditions and restrictions.

TxDMV Number & Unified Carrier Registration

Motor carriers operating intrastate commercial motor vehicles on a road or highway in Texas must get a TxDMV number.

TxDMV Number

The federal Unified Carrier Registration (UCR) Agreement requires individuals and companies that operate commercial motor vehicles in interstate or international commerce to register their business with TxDMV and pay an annual fee based on the size of their fleet.
