State Permits



Texas oversize permits are valid for three to five days. Must have permit prior to entering state.

One-half hour before sunrise to one-half hour after sunset, including Saturday and Sunday. Loads not exceeding 10′ wide, legal height (14′) or 100′ long with legal front and rear overhang may travel at night on Interstate system only. Overweight only may have continuous movement.

Restricted Travel:

City/county curfew times are now listed on the permit. Travel is allowed on major holidays depending on dimensions.

Permit Ordering Tips:

If you have a computer, temporary restrictions for many states can be accessed via the Safe Travel USA website (www.safetravelusa.com)

When you get the load on, measure it to confirm dimensions.

Make sure your weights are legal, or accurate if overweight.

Some states require a clear load description (“machinery” does not work), load make, model and serial number if applicable.

Always check your permits for accuracy when you receive them.
