Quick answer

What does an oversize permit cost in North Carolina?

NCDOT charges $12 for each dimension that is over legal, so a single-trip permit costs $12 to $48, plus $3 for every 1,000 lbs over 132,000 lbs gross. Permits come through PIMS, NCDOT's online system, and are valid for 10 days. North Carolina allows 14 ft high without a permit, and routine permitted loads move sunrise to sunset, seven days a week.

Heavy haul and oversize freight in North Carolina

North Carolina's oversize loads follow I-40 from the mountains through the Triad and Triangle to Wilmington, I-85 through Charlotte and Greensboro, I-95 across the coastal plain and I-77 north from Charlotte. We book carriers for construction equipment in the growing Charlotte and Raleigh-Durham metros, plant and energy equipment in the Piedmont, and cargo moving through the Port of Wilmington.

The western mountains change the picture. Many mountain routes are narrow and steep, and NCDOT bars loads over 10 ft wide under annual permits from 45 western routes and segments, including stretches of US-19, US-23 and US-74A. Wide loads heading to Asheville or the Tennessee line therefore move on single-trip permits with closer route planning.

What are the legal size and weight limits in North Carolina?

Under the oversize load regulations in North Carolina, a load above any of these limits needs a state oversize or overweight permit.

Width	8 ft 6 in
Height	14 ft
Semitrailer length	53 ft
Gross weight	80,000 lbs
Single axle	20,000 lbs
Tandem axle	38,000 lbs

North Carolina allows a 14 ft height and a 38,000 lb tandem axle, both above the federal baseline, and a tractor with a 53 ft semitrailer has no overall length limit on any road. The owner of a vehicle over 12 ft 6 in high is liable for any structure it strikes.

Who issues North Carolina oversize permits?

NCDOT's Oversize/Overweight Permit Unit in Garner issues annual, single-trip and superload permits through PIMS (Permit Information Management System). A single-trip permit is valid for 10 calendar days for one trip, with a return trip only if requested when it is issued.

State permits are not valid on municipal streets the state does not maintain, so city deliveries need a local permit. Applications for loads between 14 and 15 ft high must be filed in writing at least 2 business days ahead. The carrier's permit service files in PIMS.

Permit system: PIMS (Permit Information Management System), NCDOT online system for annual, single trip and superload permits; a PIMS logon account (request form emailed to PIMSaccounting@ncdot.gov) is required

What do North Carolina oversize and overweight permits cost?

request_quote Single trip: $12 for each over-legal dimension (height, length, width, and weight up to 132,000 lbs), so $12 to $48.
request_quote Over 132,000 lbs gross: add $3 for every 1,000 lbs above that.
request_quote Superloads that need an engineering study add a $100 non-refundable application fee.
request_quote Annual permit: $185 per vehicle.

Worked example: a 13 ft wide, 120,000 lb excavator load at legal height and length

Width and weight are the two over-legal dimensions, so the permit is 2 x $12 = $24, with no per-pound charge below 132,000 lbs. At 13 ft wide it needs one escort, in front on two-lane roads and behind on multi-lane highways, and it cannot travel within 10 miles of Charlotte, Raleigh, Durham or Chapel Hill during the morning or evening rush.

Seasonal weight limits in North Carolina

North Carolina has no frost or thaw program. Lower limits apply only where posted: light-traffic secondary roads, bridges posted for safe load capacity and designated truck routes. Annual permits never authorize travel on posted roads or bridges, which matters for rural pickups off the primary system.

FAQ

North Carolina Oversize Load Questions

Permits, escorts and travel rules for oversize moves in North Carolina.

How much is a North Carolina oversize permit?

A single-trip permit costs $12 for each dimension that is over legal, counting height, length, width and weight up to 132,000 lbs, so it runs from $12 to $48. Above 132,000 lbs gross, NCDOT adds $3 per 1,000 lbs, and superloads that need an engineering study pay a $100 application fee. An annual permit is $185 per vehicle.

How tall can a load be in North Carolina without a permit?

14 ft, which is 6 in more than Virginia, Tennessee and Georgia allow. The catch is liability: no one has to raise a structure for a vehicle over 12 ft 6 in high, and the owner of such a vehicle pays for any damage it causes, so tall loads still need a clearance check along the route.

When does a North Carolina load need escorts?

One escort is required over 12 ft wide, in front on two-lane roads and behind on multi-lane highways, and two over 14 ft wide on two-lane roads. Over 16 ft wide, three escorts are needed, including the State Highway Patrol. Height over 14 ft 5 in, length over 110 ft and gross weight of 150,000 lbs or more each add escort requirements.

Can oversize loads travel at night in North Carolina?

Only loads up to 112,000 lbs and 10 ft wide with no over-legal height or length can travel around the clock. Everything else moves from sunrise to sunset, seven days a week under a routine permit. Wide loads also avoid the morning and evening rush within 10 miles of Charlotte, Raleigh, Durham and Chapel Hill.

Are there mountain route restrictions in North Carolina?

Yes. NCDOT bars loads over 10 ft wide moving on annual permits from 45 western routes and segments, including parts of US-19, US-19E, US-19W, US-23, US-25/70 to the Tennessee line and US-74A between Lake Lure and Asheville. Wide equipment going into the mountains moves on single-trip permits with a route NCDOT approves.
