Texas
TxPROS · ProMiles
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.
Base: ~$61 single trip permit + county fees ($175–$1,000+ dependin…
California
CTPS / CalRoute · In-house
Most complex commuter-restriction regime in the US. Curfew windows cover the LA basin, Bay Area, and San Diego corridors; many loads cannot move at all during weekday peaks. CTPS does not auto-route many cases — expect human review for non-routine loads.
Base: $90 base (single trip; additional fees by axle weight / dime…
Pennsylvania
APRAS (Automated Permit Routing & Analysis System) · In-house
Auto-routes most in-spec loads in under a minute. The Northeast corridor catch is the holiday/curfew calendar — out-of-state drivers consistently underestimate which days block superload moves on I-78, I-80, and the Turnpike.
Base: Updated July 2025; refer to APRAS fee schedule at filing.
Ohio
OHPS (Ohio Hauling Permit System) · ProMiles
Midwest crossroads — Ohio issues roughly 335,000 hauling permits per year. OHPS replaced the legacy system in June 2020 and now auto-issues most in-spec loads.
Base: Refer to OHPS fee schedule at filing; varies by dimensions, …
Florida
PAS (Permit Application System) · In-house
Same-day issue typical for in-spec loads. Hurricane-season and special-event bans (Super Bowl, Daytona, major festivals) cause the biggest disruptions — check PAS for active travel restrictions before planning a Florida route.
Base: Single trip: $35 + $0.15/mile for oversize; $0.27/mile for o…
Illinois
ITAP (Illinois Transportation Automated Permits) · In-house
Chicago metro commuter curfews are the operational pain point. IDOT runs ITAP in-house and has publicly stayed off third-party vendors — fee and process changes come directly from the state.
Base: Refer to ITAP fee schedule at filing; varies by axle configu…
Georgia
GAPROS · ProMiles
Southeast corridor hub (I-75/I-85/I-95). Atlanta metro curfews are the catch. Single-trip permits start around $30; annual blankets available for repeat routes.
Base: ~$30 single trip permit (varies by dimensions and route).
How OS/OW permitting actually works
If you're new to oversize loads — the basics. Skip if you've done this before.
- 1
Check the limits
Federal legal limits — 8′6″ wide, 13′6″ or 14′ tall depending on state, 80,000 lb gross, 53′ trailer — are the floor. Anything beyond requires a permit in every state you transit.
- 2
File with each state
Each state issues its own permit through its own portal. There's no national one-stop. We deep-link directly to each state's official site — no broker markup.
- 3
Plan around restrictions
Holidays, weekend rules, and metro commuter curfews catch more drivers than the permit itself. Check the per-state page before committing to a delivery time.
- 4
Carry escorts where required
Pilot car / escort vehicle thresholds vary in every direction by state. Two-car escorts and state-patrol escorts kick in for superloads.

We’re building a calculator that combines the per-state data on this page with each state’s holiday and curfew calendar so you can plan a multi-state route in one screen. If you have feature requests, email support@statusdetector.com.
Looking for permit-as-a-service?
We surface the official portals so you can file direct, no markup. If you'd rather pay someone to handle the paperwork — especially for multi-state superloads — here are the established services.
Permit brokers (J.J. Keller, Comdata, Bestpass + Comdata partnership, Heavy Haul Permits) typically charge $15–$50 per state on top of the state fee. They’re worth it for complex multi-state superloads with route surveys; for routine in-spec single trips, the state portal is usually faster.
We don’t earn commission on these — they’re listed for completeness: J.J. Keller, Comdata, Heavy Haul Permits.
