Texas Oversize & Overweight Permits filed for you, 24/7

In Texas, a non-divisible load over 8 ft 6 in wide, 14 ft high or 80,000 lbs needs a TxDMV permit; loads over 80,000 lbs also pay a highway maintenance fee by weight. Send us the load and route: our permit desk quotes the price and files it with TxDMV for you.

Which permit you need

Texas permits for oversize and overweight loads

  1. Width, height or length over the legal limit

    Oversize permit

    For a load over 8 ft 6 in wide, 14 ft high or past the legal length and overhang. One trip, one route, the dates on the permit.

  2. Over 80,000 lbs or the axle limits

    Overweight permit

    For a non-divisible load over 80,000 lbs gross or over the axle limits. A highway maintenance fee is added by weight.

  3. Over both size and weight limits

    Oversize and overweight permit

    When the load is over both size and weight limits. One TxDMV single-trip permit covers both, up to 254,300 lbs.

  4. Over 254,300 lbs

    Superload permit

    Over 254,300 lbs or over the axle maximums. Texas calls it a superheavy permit; very large loads need a route inspection first.

Port and freight corridors

Texas routes with their own overweight permits

Beside the statewide single-trip permit, Texas sets up permits for heavy freight on designated routes around its ports.

  1. Houston and Freeport container routes

    An annual TxDMV permit for intermodal containers within 30 miles of Port of Houston Barbours Cut, Port of Houston IH 610, Bayport and Port Freeport, on roads TxDOT approves.

    Limits:93,000 lbs on six axles, 100,000 lbs on seven. Not valid on interstates.

  2. SH 99 Grand Parkway toll segment

    The container permit's one toll road: SH 99 from SH 146 south of IH 10 to SH 146 north of IH 10, on the east side of Houston.

    Use:Container moves between Bayport, Barbours Cut and the IH 10 corridor.

  3. Port Freeport overweight corridor

    Port Freeport issues its own overweight permits for cargo on the state highways designated for its corridor near Freeport.

    Issued by:Port Freeport, not TxDMV.

  4. US 71 / US 59 at Texarkana

    The North Texas intermodal permit covers containers in Bowie County on US 71/US 59, from the Arkansas line to the eastbound ramp onto IH 49.

    Limits:93,000 lbs gross, legal size, one year.

Texas industries

Texas permits made for the loads Texas hauls

TxDMV issues permits for specific industries on top of the general single-trip permit. Each has its own limits and paperwork.

  1. Oilfield

    Fracking trailers, rig-up trucks, well servicing units

    Separate TxDMV permits for frac equipment, rig-up trucks, well servicing units and unladen lift equipment, including annual and mileage-based options.

  2. Ports

    Intermodal containers

    Annual container permits around the Houston and Freeport ports, and a separate North Texas intermodal permit at Texarkana.

  3. Housing

    Manufactured homes and house moves

    Single-trip and annual manufactured housing permits, and a house move permit for buildings wider than 20 ft.

  4. Farm and timber

    Hay, implements of husbandry, timber

    Dedicated permits for hay loads, farm equipment and an annual timber permit, separate from the general oversize permit.

What we check before filing in Texas

  1. Overhang is its own trigger

    Rear overhang over 4 ft makes the load oversize, and over 20 ft it needs a rear escort. Send us the overhang, not only the total length.

  2. Plan around the holiday list

    Loads over 14 ft wide, 16 ft high or 110 ft long cannot move on TxDMV's holidays. We check the dates before you promise a delivery.

  3. Running up to 12 ft wide all year?

    An annual envelope permit covers up to 12 ft wide, 14 ft high, 110 ft long and 120,000 lbs. For wider single moves, a trip permit goes on top.

FAQ

Texas oversize permit questions

Do I need a permit for an oversize load in Texas?

Yes, if a non-divisible load is over 8 ft 6 in wide, 14 ft high, the legal length, or 80,000 lbs gross. TxDMV issues a single-trip permit for one move on a set route and dates.

How much does a Texas oversize permit cost?

It depends on the load's weight and the route. The TxDMV fee rises in steps over 80,000 lbs, and loads over 200,000 lbs add a supervision fee. Put your route into our permit cost calculator for an estimate, or send us the load and our permit desk quotes the exact price before filing.

When do I need an escort in Texas?

From over 14 ft wide, over 17 ft high, over 110 ft long, or with more than 20 ft of overhang. Over 16 ft wide, 18 ft high or 125 ft long you need escorts front and rear.

Can an oversize load move at night or on holidays in Texas?

Only in daytime, from 30 minutes before sunrise to 30 minutes after sunset, unless the permit allows night moves. Loads over 14 ft wide, 16 ft high or 110 ft long cannot move on TxDMV's listed holidays, and some counties and cities add rush-hour curfews.

Does Texas have an annual oversize permit?

Yes. TxDMV's annual envelope permits cover loads up to 12 ft wide, 14 ft high and 110 ft long, and the company-specific one up to 120,000 lbs. A single-trip permit can raise the width or height for one move, but not the length or weight.

What does TxDMV need before it issues a permit?

A USDOT number that is not out of service, or a $10,000 permit bond. Over 200,000 lbs you also need a Shipper's Certificate of Weight (Form 2280), and very large loads need a route inspection.

How does Route One GO get my Texas permit?

Send us the truck, trailer, load dimensions, weight and route. Our permit desk checks the Texas rules, files with TxDMV, and sends you the permit with a route map. Requests are taken 24/7.
