PermitNav

PermitNav turns your state oversize/overweight (OSOW) permit into the exact route you're allowed to drive — with truck turn-by-turn navigation, so you stay on the permitted roads instead of a generic GPS line.

NOT A GOVERNMENT APP
PermitNav is an independent app. It does not represent any government entity and is not affiliated with, endorsed by, or operated by any government agency. Oversize/overweight permits are issued only by your state's transportation agency — see the official government sources below.

BUILT FOR PERMIT LOADS
• Snap photos or upload the PDF of your state permit
• PermitNav reads the route, dimensions, and conditions automatically
• The permitted route is reconstructed road-by-road and validated against the permit
• A compliance card puts escorts, travel windows, height/width/weight, and speed conditions at a glance

NAVIGATE WITH CONFIDENCE
• Voice-guided turn-by-turn navigation that follows the permitted route
• Instant off-route alerts and guidance back to the permitted route
• Guidance keeps running with the screen locked or the app in the background (persistent navigation notification)
• Trip log records your permitted miles

ALSO IN THE BOX
• Free manual truck route builder — search a destination and go
• Saved permits and routes, synced to your account and available offline
• Route issue reporting — we review every report

STATES
New York, Pennsylvania, Kentucky, Tennessee, and Missouri permit formats are supported today. Support for more states is in development — each new state's official permit source is added to this listing when it ships.

OFFICIAL GOVERNMENT SOURCES
All permit information shown in the app is read from the official permit you upload, issued by your state. Official sources for oversize/overweight permits:
• New York — NYSDOT Special Hauling Permits: https://www.dot.ny.gov/nypermits/special-hauling-permits
• Pennsylvania — PennDOT Hauling Permits: https://www.pa.gov/services/penndot/apply-for-a-penndot-hauling-permit
• Kentucky — KYTC Overweight/Over-Dimensional Permits: https://drive.ky.gov/Motor-Carriers/Overweight-Over-Dimensional/Pages/OWOD-Permits.aspx
• Tennessee — TDOT Oversize/Overweight Permits: https://www.tn.gov/tdot/traffic-operations-division/oversize---overweight-permits.html
• Missouri — MoDOT Oversize/Overweight (OSOW) Permits: https://www.modot.org/OSOW
Road restriction alerts shown in the app (bridge heights, closures, seasonal limits) come from these same state agencies' published datasets and the Federal Highway Administration's National Bridge Inventory: https://www.fhwa.dot.gov/bridge/nbi.cfm

PLANS
The manual route builder is free. Permit auto-routing uses credits or a Pro subscription — see plans in the app.

IMPORTANT
PermitNav is a convenience aid, not a government service and not a substitute for your official permit. Always carry your official permit and obey posted signage, clearances, and your permit's conditions. Field-verify the route before every trip.
