Texas Oversize Permits for Flatbed Loads (2026)
Texas requires an oversize permit the moment a load passes 8 ft 6 in wide, 14 ft tall or 80,000 lbs gross — and TxDMV prices single-trip permits by dimensions and route mileage, so a Texas permit can cost under $40 on a short routine run or well over $500 on a long wide load.
TL;DR
Texas legal limits: 8 ft 6 in wide, 14 ft tall, 80,000 lbs gross.
TxDMV prices single-trip permits by mileage and dimensions, not one flat fee.
Escorts trigger above 14 ft wide; a high-pole car is required above 17 ft tall.
Apply through TxPROS with exact axle spacings and loaded dimensions.
Superloads over 254,300 lbs need route and structural review first.
Why Texas permit rules matter for flatbed carriers
OpenDeck, powered by Load Work covers the states flatbed and heavy haul carriers actually run, and Texas is the biggest one on the map. The state is the largest freight origin in the country — West Texas oilfield equipment, Houston petrochemical steel, East Texas lumber — so the permit math here shows up on more lanes than anywhere else.
Texas also prices permits differently than most states. Where California charges one flat fee, TxDMV scales the single-trip fee by dimensions and the mileage of the approved route. A wide load running 30 miles in Houston pays far less than the same load crossing 400 miles of West Texas — so the permit cost belongs in every lane quote.
Texas oversize permits for flatbed loads: the step-by-step
This is the working sequence for an owner-operator running a flatbed, step deck or RGN into, out of or across Texas in 2026.
Confirm the legal limits first
Texas legal limits without a permit:
Dimension | Legal limit (no permit) |
Width | 8 ft 6 in |
Height | 14 ft 0 in |
Length | 65 ft combination / 59 ft trailer |
Gross weight | 80,000 lbs (bridge formula applies) |
Single axle | 20,000 lbs |
Tandem axle | 34,000 lbs |
Texas is generous on height at 14 ft — the same envelope California gives — but strict on axle weights, so a heavy machinery load can be dimensionally legal in Texas and still overweight on the axles.
Pick the right permit category
Texas splits permitted loads into three tiers, and the tier decides how much review you get:
Routine permits cover loads within standard oversize thresholds — same-day approval is common during business hours.
Non-routine permits cover extreme dimensions or weights that need engineering and route evaluation before approval.
Superload permits are for loads over 254,300 lbs, 200 ft long or 20 ft wide — these require structural analysis of the route bridges.
Most flatbed and step deck work sits in the routine tier. Machinery and steel loads that stay under 14 ft wide with legal axle weights move fast; push past those and you move into the slower tiers.
Apply through TxPROS with exact numbers
Texas runs permits through TxPROS, the online permitting system managed by the Texas Department of Motor Vehicles (TxDMV):
Create your TxPROS carrier account before you need it — set it up in advance, not the morning of the run.
Enter the truck and trailer data: make, model, VIN, axle count and exact axle spacings.
Enter the loaded dimensions: overall length, width, height and front and rear overhang, measured on the loaded freight.
Enter weight distribution: individual axle weights plus gross vehicle weight.
Select your route. The system routes automatically around low bridges, construction zones and weight-restricted roads.
Submit and pay. Fees depend on permit type, vehicle weight and the distance of the approved route.
Read the permit conditions before you roll
Texas prints travel conditions on every permit, and the Department of Public Safety enforces them at the roadside:
Travel windows: most permitted movement is daylight-only, with exact hours on the permit.
Weekend and holiday restrictions: Texas restricts oversize travel on holidays; verify the calendar before you book a Friday pickup.
Route restrictions: the permit names specific roads. Running a different route voids the permit even if the load is the same.
Check the escort thresholds against your dimensions
Texas escort (pilot car) requirements scale directly with load size:
Width over 14 ft: one escort vehicle.
Width over 16 ft: two escorts, front and rear.
Height over 17 ft: a front pilot car with a high pole, plus advance coordination with utility companies.
Loads at the low end of the oversize range — a 10 ft wide step deck load, for example — typically run without escorts, which keeps the lane cost down.
Route around bridge clearances, not just weight
Texas has more overhead clearance problems than most states: low overpasses in Houston and Dallas, oilfield roads with soft shoulders, and long stretches where the only legal route adds 100 miles. The TxPROS routing tool screens for these, but a physical route check on the tallest part of the load is worth the hour — a bridge strike is a career-ending event and the permit does not protect you from it.
Why Texas is different from other states
Three details catch carriers running other states:
Mileage-based fees. There is no flat single-trip fee. TxDMV prices the permit by the dimensions and the route mileage, so the same load can cost under $40 in a short run and over $500 crossing Texas.
14-foot height limit. Like California, Texas allows 14 ft tall without a permit — several Eastern states cap at 13 ft 6 in. Loads that are legal in Texas can need permits on the East Coast.
Strict axle weight enforcement. Texas enforces the 20,000 lb single-axle and 34,000 lb tandem-axle limits hard, and the permit does not waive them unless the load is permitted as overweight. Distribute the load on the deck before you apply, not at the scale.
Escort and travel restrictions
Texas escort requirements are among the most predictable in the country — they key off width and height thresholds rather than case-by-case review:
One escort above 14 ft wide, two above 16 ft wide.
High-pole escort above 17 ft tall.
Daylight-only travel for most permitted loads, with hours printed on the permit.
Holiday and weekend restrictions apply — Texas restricts oversize travel on state-observed holidays.
For a hotshot or flatbed carrier running machinery, this usually means the load moves in the morning, parks by late afternoon, and covers less distance per day than a legal load would. Price the extra days into the rate.
How much do Texas oversize permits cost?
Texas prices by mileage and dimensions, so the honest answer is a range, not a number:
Short routine runs: a wide load under 100 miles often lands in the low double digits to low hundreds.
Long cross-state runs: a wide or tall load crossing hundreds of miles can run well over $500 for the single-trip permit.
Annual permits: available for recurring loads within specific dimension and route limits — the right call for carriers running set oilfield, steel or machinery lanes.
That range is the whole point: unlike California flat $16, a Texas permit cost is a line item you calculate per lane, not a constant you memorize.
Common mistakes Texas flatbed carriers make
Assuming the permit covers any route. It covers the route on the paper. A different road — even one that looks shorter — voids the permit.
Guessing axle weights. TxPROS approval depends on exact axle spacings and weights. Estimated numbers get the permit questioned at the scale.
Booking a Friday pickup. Texas restricts oversize travel on holidays and weekends, and a Friday afternoon pickup often means the load sits over the weekend.
Ignoring superload review time. Loads over 254,300 lbs need route and structural analysis that takes weeks, not hours. Quote those loads with a realistic start date.
Pricing oversize loads out of Texas
The permit is a calculable line item, but the escort and travel-window costs are where margins move:
A load that needs two escorts and runs 16 ft wide needs a rate that reflects two pilot cars and reduced running time.
A routine-tier load under 14 ft wide is the cheapest oversize profile to run — quote it competitively and you win the lane.
Annual permit holders should amortize the fee across the lane, not recover it on the first load.
When you are building the lane, use OpenDeck, powered by Load Work to filter open-deck freight by trailer type, weight and length. Set load alerts around the home ZIP and radius you choose, and check OpenDeck pricing — every plan shown there is a Load Work plan, and account setup, load access and billing all happen inside the Load Work platform.
FAQ
How much does a Texas oversize permit cost in 2026?
Texas does not charge a flat fee — TxDMV prices single-trip permits by dimensions and route mileage, so costs range from under $40 for a short routine run to well over $500 for a long wide or tall load. Annual permits are available for recurring loads.
What is the legal width limit in Texas without a permit?
8 ft 6 in. A load wider than 8 ft 6 in needs a TxDMV oversize permit before travel, paired with a 14 ft height limit and 80,000 lbs gross weight.
When does a Texas oversize load require an escort?
One escort vehicle is required above 14 ft wide, two escorts above 16 ft wide, and a high-pole pilot car above 17 ft tall. Daylight-only travel applies to most permitted loads.
How do I apply for a Texas oversize permit?
Through TxPROS, the TxDMV online permitting system. You enter truck and trailer data, exact axle spacings, loaded dimensions, axle weights, and select a route; the system screens it for bridges and restrictions.
Is there an annual oversize permit in Texas?
Yes. Texas offers annual permits for recurring loads within specific dimension and route limits — the right fit for carriers running set oilfield, steel or machinery lanes.
What counts as a superload in Texas?
Loads over 254,300 lbs, 200 ft long or 20 ft wide are treated as superloads and need route and structural analysis before approval — a review measured in weeks, not hours.
One last thing
Texas is one of the few states where the permit fee is predictable before you apply: dimensions times route mileage. That makes it the easiest oversize state to quote accurately — but only if you know the route mileage before the quote. Pull the route first, then the permit estimate, then the rate. A carrier who prices Texas oversize freight on a flat-fee assumption from another state leaves real money on the table.
