North Carolina legal limits (no permit needed at or under these)
Axle weight limits
Gross weight is one ceiling; each axle group carries its own limit, and a load can be legal on gross weight yet overweight on an axle. Exceeding any of these needs an overweight permit.

Permit fees
- Single trip
- $12 ($12 for each dimension over the lawful dimension, counting height, length, width, and weight up to 132,000 pounds. The fee is per over-limit dimension, not a flat per-permit charge, so a load that is both overwidth and overweight pays $24. A single-trip permit is valid for 10 calendar days.)
- Annual permit
- $185 ($185 per vehicle for the annual permit to move commodities other than house trailers or trailer frames, and $200 per vehicle for the annual permit to move house trailers or trailer frames. Both are set by statute and both run one year from the date of issuance. Neither the Department nor the Board may require review or renewal of an annual permit more than once per calendar year.)
- Annual eligibility
- The general non-divisible commodity annual permit covers up to 12 feet wide (14 feet for farm equipment under special restrictions), 14 feet high, 105 feet long, and 132,000 pounds. Loads at or under 90,000 pounds move on all North Carolina highways where posted road and bridge limits allow, provided the vehicle or combination has a minimum extreme wheelbase of 51 feet. Over 90,000 pounds the permit lists specific routes, up to 10 per permit. The power unit must have a registered vehicle weight of 80,000 pounds to obtain an overweight permit. Restricted routes are listed on fact sheet PF-8.
Single-trip permit fee schedule
A single-trip permit stacks a base fee with a weight-tiered maintenance fee, and the heaviest loads add a supervision fee.

Escort thresholds
Travel restrictions
- Daylight only
- Default. Authorized time of movement for permitted loads is Monday through Sunday, sunrise to sunset, unless the permit states otherwise. Continuous travel 24 hours a day, 7 days a week, 365 days a year is authorized for a vehicle or combination up to a permitted gross weight of 112,000 pounds and up to 10 feet wide provided the permitted vehicle has no other over-legal dimension of height or length.
- Curfews
- Permitted vehicles or combinations exceeding 12 feet in width may not travel within a 10-mile radius of the city limits of Charlotte, Raleigh, Durham, or Chapel Hill between 7:00 a.m. and 9:00 a.m. or between 4:00 p.m. and 6:00 p.m. Sixteen-foot-wide mobile and modular homes move Monday through Saturday from 9:00 a.m. to 2:30 p.m. only.
- Weekend / holiday
- The permit office publishes an annual holiday schedule. On most state holidays travel continues under a previously issued permit. Three holidays carry a full moratorium on overwidth, overheight, and overlength permitted vehicles and on combinations over 112,000 pounds gross: Independence Day, from noon Friday July 3, 2026 until noon Monday July 6, 2026; Thanksgiving, from noon Wednesday November 25, 2026 until noon Friday November 27, 2026; and Christmas, from noon Thursday December 24, 2026 until noon Monday December 28, 2026.
Superload and beyond-permit review
Loads past the standard single-trip permit thresholds get individual state review rather than an off-the-shelf permit.
A superload permit is required above 132,000 pounds gross weight or at 17 feet or greater in width. The maximum weight is determined by the total number of axles, the design of the axle configurations, and the bridge structures along the specific route of travel.
Applications should be submitted at least 10 business days before the anticipated move to allow internal and bridge engineering reviews, and applicants should allow a minimum of 16 business hours before calling to check status. An approved application stays in a pending-issue file for 90 days; bridge engineering studies expire after 90 days and the application is then void. Continuous travel is not authorized for a superload.
Legal limits before you need a permit
North Carolina publishes one statewide size and weight table rather than separate interstate and non-interstate versions. Width, height, length by configuration, gross weight, and axle groups all come out of Chapter 20, and the table below carries each with its section.
Two of those numbers surprise out-of-state carriers. Legal height is taller than the figure common next door, and the legal tandem is heavier than what most states allow, with an added exception letting two consecutive sets of tandems each carry a lower published weight when the outer axles sit far enough apart. Single-axle weight and maximum gross weight stay where the rest of the country puts them.
What varies off the interstate system is the road, not the limit. The Department may designate light-traffic roads with lower posted axle limits, posted bridge limits always control, and the axle-group tolerance never applies on interstate highways or to posted bridges.
Single-trip permits
A single-trip permit covers one movement over the legal limits and stays valid for a published run of calendar days. Pricing is unusual. North Carolina charges per over-legal dimension rather than a flat permit price, counting height, length, width, and weight up to a published weight ceiling, then adds a per-thousand-pound charge above that ceiling. A load that is both overwidth and overweight pays twice.
Applications needing an engineering study for pavement or structures carry a nonrefundable application charge. The permitted envelope has its own ceilings on width, height, and weight by axle count, with lower gross weights allowed when the extreme wheelbase is short. Anything past the width or weight ceiling becomes a superload.
Annual permits
Annual permits are bought per vehicle and run one year from the date of issuance. The general version covers non-divisible commodities inside a published width, height, length, and gross weight envelope, with a wider allowance for farm equipment under special restrictions. Neither the Department nor the Board may require review or renewal more than once in a calendar year.
Routing depends on weight. At or below a published weight line the permit is good on all state highways where posted road and bridge limits allow, provided the vehicle meets a minimum extreme wheelbase. Above that line the permit names specific routes, capped at a published count per permit, and the power unit must be registered at a published weight before an overweight permit issues.
Mobile and modular homes get their own annual permits at three published widths, each with its own routing and escort rules.
Escort requirements
North Carolina certifies its escort operators, which is not the norm. Every escort vehicle operator must hold an approved state certification before escorting a load here and must carry the credentials in the vehicle for inspection. The Department runs the program with a defensive driving course, community college classes, third-party instructors, an online renewal course, and reciprocation agreements with other states.
Escort counts phase in by dimension. Width, height, length, rear overhang, and weight each carry their own threshold, placement rule, and count, and the widest loads take a State Highway Patrol escort alongside civilian ones. The escort table below lists each threshold with its placement.
Equipment rules are prescriptive: a lettered banner across the bumper, amber warning lighting visible for a published distance, headlights burning during movement, a height pole once the load tops the height threshold, two-way radio contact, a stop and slow paddle, a high-visibility vest, retroreflective triangles, company identification signs, and a fire extinguisher of a published rating.
When permitted loads can move
Sunrise to sunset is the default, seven days a week, unless the permit says otherwise. Around-the-clock travel is authorized only for a permitted vehicle inside a published gross weight and width envelope with no other over-legal dimension of height or length, and the live permit page carries a more generous width allowance than the older single-trip publication does. Where the two disagree, the live page is what we record.
Curfews close a radius around Charlotte, Raleigh, Durham, and Chapel Hill to loads over a published width during weekday rush windows. Three holidays carry a full moratorium on overwidth, overheight, and overlength permitted vehicles and on the heaviest combinations. Convoy travel is prohibited outright, and night movement of a load past a published width takes amber lamps at the widest points.
One honest gap: no statewide wind or weather movement restriction was published on the permit pages, publications, or handbook read in this pass, so none is recorded.
Superloads
Past the single-trip ceiling the move becomes a superload: above a published gross weight, or at or beyond a published width. Maximum weight is settled case by case from the axle count, the design of the axle configurations, and the bridge structures along the route.
Lead time is the constraint. Applications go in well ahead of the move so internal and bridge engineering reviews can run, an approved application sits in a pending-issue file for a limited window, and a bridge engineering study expires after that window, voiding the application. Continuous travel is never authorized for a superload, and a return trip needs its own application.
Pricing stacks the nonrefundable application charge, the per-dimension base charge, and the per-thousand-pound charge above the weight ceiling.
How to read this page
A value reading "Not confirmed" means we could not verify the figure on an official agency page at review time, so it stays open rather than guessed. Superload moves above the standard permit thresholds get individual review by the state; contact the permit office named on this page.

Frequently asked questions
What can I haul in North Carolina without a permit?
- Anything inside the published statewide limits for width, height, length by configuration, gross weight, and axle groups. Legal height here is taller than in several neighboring states and the legal tandem is heavier, so check the sourced limits before assuming a load that was legal at home is legal here.
How much does a North Carolina single-trip oversize permit cost?
- It depends on how many dimensions are over. North Carolina charges per over-legal dimension, counting height, length, width, and weight up to a published ceiling, then adds a per-thousand-pound charge above it. Applications needing an engineering study carry a nonrefundable charge on top. The schedule below lists each component.
Do North Carolina escorts have to be certified?
- Yes. Every escort vehicle operator must hold an approved state certification before escorting an oversize or overweight load and must carry the credentials for inspection. The Department runs its own program, with community college classes, third-party instructors, an online renewal course, and reciprocation agreements.
Can permitted loads move at night in North Carolina?
- Only when the permit allows it. The default window is sunrise to sunset, and around-the-clock travel is limited to permitted vehicles inside a published weight and width envelope with no other over-legal dimension. Night movement of a wide load takes amber lamps at the widest points.
What counts as a superload in North Carolina?
- A load above the published gross weight ceiling, or at or beyond the published width. Superload permits need internal and bridge engineering review before they issue, so applications go in well ahead of the move, and continuous travel is never authorized.
