North Carolina legal limits (no permit needed at or under these)
- Width
- 8.5 ft102 inches on all roads in North Carolina. A six-inch tolerance applies when hogsheads of tobacco are transported, and sheet or bale tobacco may reach 114 inches at the top of the load with the bottom at the truck bed no wider than 102 inches.
- Height
- 14 ftNo vehicle, unladen or with load, may exceed 14 feet. North Carolina does not require any structure to be raised or rebuilt to pass a vehicle over 12 feet 6 inches, and the owner or operator of a vehicle over 12 feet 6 inches is liable for damage to any structure it strikes.
- Gross weight
- 80,000 lbThe 80,000-pound maximum gross weight limit is named in the tolerance provision of G.S. 20-118(h); axle-group gross weights come from the bridge-formula table in G.S. 20-118(b)(3).
- Off interstate limits
- North Carolina publishes one statewide size and weight table rather than separate interstate and non-interstate tables. What varies off the interstate system is the road, not the limit: the Department may designate light-traffic roads and post lower axle limits on them, posted bridge limits under G.S. 136-72 always control, and the 10 percent axle-group tolerance in G.S. 20-118(h) does not apply on interstate highways or to posted bridges.
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
What the escort itself has to be
Hitting the threshold is only half of it. The escort vehicle, its equipment, its driver's certification and where it rides are all regulated, and the carrier is the one holding the permit when they are not met.
- Escort driver certification
- North Carolina certifies escort vehicle operators. Every escort vehicle operator must obtain an approved escort certification before performing escort duties in the state, and the certification credentials must be carried in the vehicle and available for inspection by law enforcement. NCDOT runs an Escort Vehicle Operator Program with a defensive driving course, community college classes, third-party instructors, an online renewal course, and reciprocation agreements with other states.
- What counts as an escort vehicle
- The escort vehicle must be a single motor vehicle with a GVWR of at least 2,000 and not more than 26,000 pounds. Escort vehicles may not pull a trailer of any kind or transport hazardous materials.
- Equipment the escort vehicle carries
- Yellow WIDE LOAD or OVERSIZE LOAD banner in black 10-inch by 1.5-inch brush stroke lettering spanning the bumper width; rotating or strobe amber light on the roof visible 500 feet in all directions; headlights burning during movement; height pole indicator for loads over 14 feet 5 inches; two-way radio contact with the load and other escorts; an 18-inch octagonal stop/slow paddle with 6-inch letters; approved high-visibility vest; at least three bi-directional retroreflective triangles; a company identification sign at least 8 by 12 inches on each side; and a minimum five-pound BC or ABC fire extinguisher.
- How the escort must operate
- No passengers or animals may ride in the escort vehicle unless the passenger holds an approved escort certification. Escort operators may not use cell phones, tablets, computers, or other non-factory electronic devices except to communicate hazard information to the escorted vehicle. Escorts must monitor trailing traffic and pull over periodically, slowing to no more than 25 mph, to let queued traffic pass.
Escort rules beyond the thresholds
Knowing when you need an escort is half of it. These are the North Carolina rules on who may run one, what the vehicle has to carry, and how the move is conducted.
- Certification
- North Carolina certifies escort vehicle operators. Every escort vehicle operator must obtain an approved escort certification before performing escort duties in the state, and the certification credentials must be carried in the vehicle and available for inspection by law enforcement. NCDOT runs an Escort Vehicle Operator Program with a defensive driving course, community college classes, third-party instructors, an online renewal course, and reciprocation agreements with other states.
- Vehicle
- The escort vehicle must be a single motor vehicle with a GVWR of at least 2,000 and not more than 26,000 pounds. Escort vehicles may not pull a trailer of any kind or transport hazardous materials.
- Equipment
- Yellow WIDE LOAD or OVERSIZE LOAD banner in black 10-inch by 1.5-inch brush stroke lettering spanning the bumper width; rotating or strobe amber light on the roof visible 500 feet in all directions; headlights burning during movement; height pole indicator for loads over 14 feet 5 inches; two-way radio contact with the load and other escorts; an 18-inch octagonal stop/slow paddle with 6-inch letters; approved high-visibility vest; at least three bi-directional retroreflective triangles; a company identification sign at least 8 by 12 inches on each side; and a minimum five-pound BC or ABC fire extinguisher.
- Conduct
- No passengers or animals may ride in the escort vehicle unless the passenger holds an approved escort certification. Escort operators may not use cell phones, tablets, computers, or other non-factory electronic devices except to communicate hazard information to the escorted vehicle. Escorts must monitor trailing traffic and pull over periodically, slowing to no more than 25 mph, to let queued traffic pass.
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.
- Wind / weather
- No statewide wind or weather movement restriction was published on the NCDOT permit pages, publications, or handbook read in this pass, so none is recorded.
- Continuous travel currency
- The 10-foot width allowance is the Permit Unit's Continuous Travel Qualifications Update, published at the top of the Oversize/Overweight Trucking Permits page and read there on 2026-07-29. It is more permissive than the criteria still printed in Publication ST-1 (Rev. 11/19), which conditions continuous travel on a width no greater than 8 feet 6 inches, a height no greater than 13 feet 6 inches, and combined front and rear overhang no greater than 10 feet. Where the two disagree, the figure recorded here is the one on the live agency page, not the older publication.
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.
More North Carolina permit rules
- Permit trigger: detail
- A permit is generally required if weight exceeds legal weight under North Carolina law, total width is over 8 feet 6 inches, overall height is greater than 14 feet, or a single vehicle is over 40 feet or a vehicle combination is over 60 feet in length. A truck tractor with a 53-foot semitrailer has no overall length limitation on any road.
- Weight tolerance: detail
- A vehicle may exceed the maximum and inner axle-group weight limits in G.S. 20-118(b)(3) by a tolerance of 10 percent. The tolerance does not authorize exceeding the single-axle or tandem-axle limits or the 80,000-pound maximum gross weight, does not apply to a vehicle exceeding posted bridge limits or operating on interstate highways, and does not authorize exceeding the weight for which the vehicle is licensed under G.S. 20-88. No tolerance on single-axle or tandem-axle weight may be granted administratively.
- Single trip fee note
- $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.
- Single trip limits: max width
- 16 feet 11 inches; applications over 16 feet wide must be submitted in writing at least two business days before the move
- Single trip limits: max height
- Determined by vertical clearance along the authorized route; applications over 14 feet high must be submitted in writing at least two business days before the move
- Single trip limits: permitted gross weights
- 5 axles 112,000 lb (94,500 lb if the extreme wheelbase is under 51 feet); 6 axles 120,000 lb (108,000 lb under 51 feet); 7 axles 132,000 lb (122,000 lb under 51 feet)
- Single trip limits: permitted axle weights
- Steer 20,000 lb; single 25,000 lb; tandem 50,000 lb; tridem 60,000 lb; four or more in a grouping 68,000 lb
- Annual permit fee note
- $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 permit 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.
- Annual permit details: mobile home widths
- Annual mobile and modular home permits are issued at 12, 14, and 16 feet wide, each with its own routing and escort rules. The 16-foot annual permit covers up to 30 specific routes from one named manufacturer to licensed dealerships in state and out of state.
- Escort notes: certification
- North Carolina certifies escort vehicle operators. Every escort vehicle operator must obtain an approved escort certification before performing escort duties in the state, and the certification credentials must be carried in the vehicle and available for inspection by law enforcement. NCDOT runs an Escort Vehicle Operator Program with a defensive driving course, community college classes, third-party instructors, an online renewal course, and reciprocation agreements with other states.
- Escort notes: vehicle
- The escort vehicle must be a single motor vehicle with a GVWR of at least 2,000 and not more than 26,000 pounds. Escort vehicles may not pull a trailer of any kind or transport hazardous materials.
- Escort notes: equipment
- Yellow WIDE LOAD or OVERSIZE LOAD banner in black 10-inch by 1.5-inch brush stroke lettering spanning the bumper width; rotating or strobe amber light on the roof visible 500 feet in all directions; headlights burning during movement; height pole indicator for loads over 14 feet 5 inches; two-way radio contact with the load and other escorts; an 18-inch octagonal stop/slow paddle with 6-inch letters; approved high-visibility vest; at least three bi-directional retroreflective triangles; a company identification sign at least 8 by 12 inches on each side; and a minimum five-pound BC or ABC fire extinguisher.
- Escort notes: conduct
- No passengers or animals may ride in the escort vehicle unless the passenger holds an approved escort certification. Escort operators may not use cell phones, tablets, computers, or other non-factory electronic devices except to communicate hazard information to the escorted vehicle. Escorts must monitor trailing traffic and pull over periodically, slowing to no more than 25 mph, to let queued traffic pass.
- Escort notes: multiple dimensions
- Multiple escorts may be required when a load is over-dimension in more than one respect, and additional escorts may be required for any combination based on width, length, height, weather, geography, or route as determined by the issuing agent.
- Penalties: no permit or off route
- A fine of $500 for operating without the issuance of a permit, moving a load off the route specified in the permit, falsifying information to obtain a permit, or failing to comply with the dimension restrictions of a permit.
- Penalties: missing escorts
- A fine of $1,500 for operating without the proper number of certified escorts as determined by the actual loaded weight or size of the vehicle combination.
- Penalties: overweight axle
- Single-axle and tandem-axle overweight penalties run 4 cents per pound for the first 1,000 pounds over, 6 cents per pound for the next 1,000, and 10 cents per pound for each additional pound. Axle-group overweight penalties run 2 cents per pound for the first 2,000 pounds over, 4 cents for the next 3,000, and 10 cents for each pound beyond 5,000.
- Seasonal permits note
- Sourced negative. North Carolina publishes no harvest-season or seasonal-commodity oversize permit. The permit families the Oversize/Overweight Permit Unit does publish are the general non-divisible commodity single-trip and annual permits, mobile and modular home permits at 12, 14, and 16 feet wide, superload permits, house-move permits with a separate house mover license (PF-9), sealed ship container movement, and self-propelled equipment movement. Farm equipment and machinery in use for agricultural purposes are exempt from the G.S. 20-119(b) permit fees, and G.S. 20-116(j) lets self-propelled farm equipment up to 25 feet wide operate under daylight, flag, and flagman conditions without a permit.
- Safety equipment: banner
- A 7-foot by 18-inch yellow banner with black 10-inch high, 1.5-inch brush stroke lettering reading OVERSIZE LOAD or WIDE LOAD on the front and rear bumpers of any combination more than 10 feet wide. Two separate banners totaling 7 feet may be used to leave room for plates and decals.

The North Carolina permit office
- Note
- Faxed permit applications have not been accepted since August 1, 2025. Carriers not already ordering online must create a PIMS account using the PIMS Online Account Request Form. A telephone request may carry up to four permit requests; multiple permits for one multi-sectional mobile home count as one request. Payment is by company check or by American Express, MasterCard, Discover, or VISA. Personal checks cannot be accepted.
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. For the rest of the North Carolina permit stack, see North Carolina trucking permits.
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.
