Texas Oversize / Overweight Permits
Largest US permit volume; most in-spec loads auto-issue in minutes. County-fee complexity is the most common gotcha — a single trip permit can balloon when crossing multiple counties.
At a glance
Fast facts. The official portal is the final word.
Base fee
~$61 single trip permit + county fees ($175–$1,000+ depending on counties crossed)
Turnaround
Minutes for auto-routed permits; superloads (route survey, bridge analysis) take days.
Auto-issue
Most routine in-spec single trips auto-route and auto-issue within minutes.
Pilot car / escort pattern
General thresholds. Route-specific rules can be stricter — verify at filing.
Pilot cars generally required for width above ~12 ft, height above ~14′6″, or length above ~90 ft. Two escorts may be required at higher thresholds. County-specific rules apply.
Holiday & curfew pattern
When you can't move. Always confirm the exact calendar with the state at filing.
Federal holidays plus the day before/after often restricted. Peak commuter hour curfews apply in DFW and Houston metros. Sunset-to-sunrise travel restrictions for many oversize loads.
Common gotchas
The things drivers consistently get tripped up on.
County fees can exceed the base state fee by 5–10×. Always check the routing quote before filing.
Houston and DFW metro commuter curfews catch drivers who don't plan around rush hour.
