Texas Oversize Permits: Requirements and Fees

Defining Legal Dimensions vs. Oversize Loads

You must determine whether your load exceeds Texas legal limits before you proceed to permit application. The 2026 standard maximums for a vehicle (including load) without a permit are:

• Width: 8'6" (8 feet, 6 inches)
• Height: 14'0"
• Length: 45' for a single motor vehicle; 59' for a semitruck-trailer combination.
• Gross Vehicle Weight (GVW): 80,000 lbs.

All cargo that goes beyond these limits needs an oversize load permit which specifically applies to non-divisible items that require special handling because they cannot be easily disassembled.

Texas OS/OW Permit Types and Fees (2026)

The TxDMV uses a fee system that charges different rates based on how long permits last and how serious their weight and size violations are. The TxPROS system applies a fixed service fee to all online transactions which consists of a standard charge of $0.25 plus 2.25%.

Single-Trip Permits

These permits permit one-time travel between two locations for a duration of five days.

Time-Based and Annual Permits

Frequent haulers will find better savings through time-based permits which enable them to save money.

• 30/60/90 Day Permits: The fees for width and length exceptions range between $120 and $240.
• The Annual Envelope Permit: Costs $4,000 and lets a vehicle transport different loads that fit within designated size limits for one year.
• Over Axle/Over Gross Weight Tolerance: The annual permit are divisible goods to transport through selected counties at a cost that ranges from $270 to $1,095.

Superheavy Loads and Engineering Reviews

A load which exceeds 254,300 pounds or specific axle weight limits is categorized as Superheavy. The TxDOT bridge and pavement analysis process requires a lead time of 3 to 4 weeks for bridge and pavement evaluation.

• Superheavy Analysis Fee: A $500 fee is charged if a private engineer's report must be reviewed by the state.
• The Vehicle Supervision Fee: imposes a charge of $35 for loads that exceed 200,000 pounds to cover the costs associated with monitoring the delivery route.

Escort Vehicle and Route Inspection Requirements

Texas requires Pilot/Escort Vehicle (P/EV) services to operate according to the load size which needs to be transported. The absence of required escorts can result in immediate orders to suspend all operations.

• Width: Two-lane roads require escorts for loads that exceed 14 feet in width.
• Height: Before receiving a permit any load that exceeds 18'11" must present a certified Route Inspection Certification.
• Night Movement: Most loads wider than 10 feet cannot travel at night unless they use Interstates and specific four-lane divided highways.

Surety Bond Requirements

The state mandates a Texas Oversize Permit Bond for most OS/OW permits because they must secure the protection of public infrastructure.

• Standard Oversize/Superheavy Bond: The bond amount stands at $10,000.
• Over Axle/Over Gross Tolerance Bond: The bond amount stands at $15,000.

Anyone who needs to obtain bonds must spend about $100 per year to obtain them because bond acquisition serves as a mandatory requirement before permit acquisition.

Compliance Checklist for 2026

• Verify Dimensions: Measure the total height, width, and length (including overhangs).
• USDOT Status: Your USDOT number must be active because it cannot exist in an Out-of-Service status.
• Route Mapping: Use TxPROS to check for vertical clearance and load-zoned bridges on your intended path.
• Proof of Insurance: The Texas minimum liability requirement mandates you to maintain coverage of $30,000 for bodily injury per person and $60,000 for total bodily injury per accident and $25,000 for property damage. Interstate carriers must meet federal higher liability limits.
