Running Freight Through Texas
Long In-State Hauls
Texas is large enough that a run entirely inside the state, such as El Paso to Houston, can exceed 700 miles, so Texas mileage often dominates a carrier's quarterly IFTA return even on multi-state trips.
Active Port-of-Entry Inspections
Texas runs permanent and mobile weigh and inspection stations along its major interstates and border crossings, and commercial vehicles should expect to stop when stations are open and lights are flashing.
Toll Roads Around Major Metros
While most rural Texas interstates are toll-free, the Dallas, Houston, and Austin metro areas have toll roads and managed lanes that carriers should factor into route planning and cost estimates.
IFTA and Trucking in Texas: What to Know
Texas is the single largest state trucking market in the country by miles driven, and that scale shows up in how the state manages IFTA reporting and road enforcement. Carriers running Texas lanes deal with some of the longest in-state hauls in the network (El Paso to Houston alone runs over 700 miles), so Texas miles often make up a disproportionate share of a carrier's total quarterly IFTA return even when the truck is based somewhere else.
IFTA Filing for Texas Miles
Texas participates in IFTA like every other member jurisdiction, meaning a carrier based outside Texas still reports Texas miles and Texas fuel purchases on their regular quarterly return through their home base state. Because Texas trips tend to run long, it's worth keeping careful fuel receipts for any diesel purchased in-state, since those gallons offset the tax owed on Texas miles rather than requiring a separate Texas filing.
Weigh Stations and Enforcement
The Texas Department of Public Safety operates weigh and inspection stations at fixed locations along major interstates, particularly near the state's borders with Louisiana, Oklahoma, New Mexico, and along the Mexico border crossings, where both weight and cross-border compliance are checked.
Beyond fixed stations, Texas also uses mobile enforcement units and roadside inspections, so carriers running through the state regularly should keep their logs, permits, and registration paperwork current and easy to produce.
Permits and Oversize Loads
Texas issues oversize and overweight permits through its Department of Motor Vehicles, and the state's wide highway network makes it a common corridor for oversized freight moving between the Gulf Coast, the Southwest, and the rest of the country. Carriers running specialized or oversize loads through Texas should confirm permit requirements before the trip rather than at the state line.
Weather and Seasonal Planning
Texas covers enough geography to span several distinct weather patterns in a single trip: Gulf Coast humidity and hurricane risk in the late summer and fall, Panhandle winter storms and occasional ice in the north, and extreme summer heat across the entire state that can stress tires and cooling systems on long hauls.
Carriers Running Texas Freight
“Texas runs are long, but that's the point. I can build a whole week out of triangle freight without ever leaving the state, and my IFTA return every quarter reflects that.”
“I keep every Texas fuel receipt separately just because the miles add up so fast here. Makes quarterly filing a lot less of a headache.”
