When you think of Texas, you picture endless highways, sprawling landscapes, and a booming freight industry. But if you’re driving a truck in Texas, there’s more to it than big skies and long roads.

Here’s the open loop: From oversize permits to weight restrictions and border crossings, Texas trucking laws are complex. Missing even one regulation could mean hefty fines, delays, or worse. So how do you prepare? Let’s break down everything you need to know before hitting the road in the Lone Star State.

Why Texas is a Trucking Powerhouse

• Texas has the largest highway network in the U.S. — over 313,000 miles of road.

• It borders Mexico, making it a key gateway for cross-border freight.

• Oil, gas, agriculture, and manufacturing all fuel demand for heavy trucking.

Psychology cue (Ambition): If you want to succeed in the freight industry, Texas isn’t optional — it’s essential.

Key Rules for Driving a Truck in Texas

1. Oversize and Overweight Permits (OSOW Permits)

• Escort vehicles may be required for certain dimensions.

2. Hours of Service Rules

Texas follows FMCSA Hours of Service (HOS) regulations:

• 14-hour limit after coming on duty.

• 30-minute rest break required within 8 hours.

3. Road and Bridge Restrictions

• Not all Texas roads can handle heavy loads. TxDOT provides routing maps to prevent bridge strikes and road damage.

• Some county roads may restrict truck traffic entirely.

4. Border Crossings and Trade

• The Texas–Mexico border is one of the busiest in the world for trucking.

• Drivers must comply with Customs and Border Protection (CBP) and USMCA trade rules when hauling international freight.
