How to read a North Carolina oversize permit
NCDOT's Oversize/Overweight Permit Unit issues permits through PIMS, its online system; faxed applications ended August 1, 2025. The route is printed in the permit's 'Via Routes' section, and NCDOT requires an exact origin, a detailed route and an exact destination, with county and state road numbers.
Issued by the North Carolina Department of Transportation, Oversize/Overweight Permit Unit through PIMS (Permit Information Management System). Written from NCDOT's published rules; we haven't read a real North Carolina permit yet.
How to read the route
NCDOT hasn't published a sample permit, but its handbook refers to 'the route of travel provided in the “Via Routes” section of this permit.' A single-trip route must include the exact origin, a detailed route and the exact destination, with county and state road numbers. Requirements and restrictions are written on each permit for that load, so read the whole permit, not just the route.
Road names on North Carolina permits
| On the permit | Means |
|---|---|
| I 26 | Interstate 26 (NCDOT also writes it I-26) |
| US 25 (Exit 54) | U.S. Highway 25 at interstate Exit 54 |
| NC 146 (Long Shoals Road) | North Carolina Highway 146, with its local road name |
| SR 3482 (Ferry Road) | State secondary road 3482, with its local name. NCDOT lists secondary road numbers by county; its Secondary Roads lookup searches by county and road number. |
Where the route starts and ends
NCDOT requires the exact origin and exact destination. A return trip to the origin is allowed only if you ask for it when the permit is issued and finish it before the permit expires. How the printed permit words the ends isn't published.
