Hauling heavy loads in Texas is a complex process including planning, logistics and strict adherence to government regulations. Whether it’s obtaining oversize permits, escort requirements or vehicle dimensions, management of Texas rules is essential in the smooth and efficient transportation of your loads.
Permit Requirements for Overweight and Oversized Loads
Texas oversize permits are valid for either three to five days (usually one could operate within 3 days), and as with the oversize permitting process, would need to be secured prior to entering the state. Each single-trip permit will require how the load is described, as well as further specifics depending on the nature of the freight (e.g., make, model, and serial number when applicable). Using such language as the load as “machinery” is not usable by a load planner.
Oversize vehicle permit requirements vary based on dimensions and weight.
Overweight permits allow continuous movement, but axle weights must comply with state weight limits.
Super Loads (exceeding standard routine permit limits) require route surveys and extended approval times.
Operating Hours & Travel Restrictions
Standard Operating Times: Daylight hours only (½ hour before sunrise to ½ hour after sunset).
Night travel exception: Loads ≤ 10′ wide, 14′ height, or 100′ length (with legal overhangs) may travel at night on Interstates.
Restricted Travel:
City/county curfews are listed on permits.
Holiday travel depends on load dimensions (check permit for restrictions).
