New Jersey legal limits (no permit needed at or under these)
- Length: tractor_semitrailer_overall
- no maximum, provided the trailer or semitrailer length complies with N.J.S.A. 39:3-84.a(4)
- Length: trailer_or_semitrailer_note
- 53 feet on all highways when overall width does not exceed 8 feet, and 53 feet on the National Highway Network and the New Jersey 102-inch Truck Route Network when overall width is 8 feet 6 inches. On a trailer longer than 48 feet and up to 53 feet the kingpin to rear axle center distance cannot exceed 41 feet.
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
- $10 (The base fee is $10.00 for a permit that is either oversize or overweight, and $20.00 when the vehicle is both, in which case the excess size and excess weight fees also apply. Every permit transaction adds a $12.00 transaction fee plus a service charge of 5 percent of the total permit fee; a single-trip permit for a vehicle that is both oversize and overweight is charged that transaction fee once. A single-trip permit is valid for five days, and a one-day extension may be granted for hazardous road conditions or a vehicle breakdown if the request reaches the MVC before the permit expires.)
- Annual eligibility
- The only true annual permit is the ocean borne containerized cargo multiple-trip permit. It covers a tractor semitrailer combination carrying sealed containers of the type used in international ocean-going commerce bearing a U.S. Customs, other government agency, or shipper seal. Combined gross vehicle weight including the load cannot exceed 90,000 pounds, tandem axle weight cannot exceed 38,000 pounds, and a tri-axle trailer configuration cannot exceed 56,400 pounds. Moves must be of legal dimension; the permit is not valid for oversize or overdimensional loads. The original permit with the raised State seal must be in the vehicle, photocopies are not accepted, and travel is barred on structures identified as restricted on the permit.
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.

Travel restrictions
- Daylight only
- Oversize permits only. An oversize permit is not valid during the nighttime hours of sunset to sunrise. The Chief Administrator may grant a written waiver of the night or holiday restriction where traffic congestion would be reduced, where the applicant can justify a business hardship, or in an emergency, and the waiver request must accompany the permit application. Overweight permits for loads within legal dimensions are valid 24 hours a day, seven days a week.
- Weekend / holiday
- An oversize permit is not valid on New Year's Day, Memorial Day and the Friday before Memorial Day, Independence Day, Labor Day and the Friday before Labor Day, Thanksgiving Day and the Wednesday before Thanksgiving Day, and Christmas Day. A holiday falling on a Sunday moves the restriction to the following Monday; a holiday falling on a Saturday moves it to the preceding Friday.
Legal limits before you need a permit
Width is the New Jersey trap. The wider allowance applies on the national network and on the state's designated truck route network; everywhere else the limit drops, which makes an ordinary wide trailer oversize on an unlisted local road. The network hierarchy is set by its own rule chapter, which ranks the national network first, a state access network second, and treats every other local road as terminal access only.
Height is uniform statewide. Length depends on configuration, from a single truck through combinations and automobile transporters, with a separate kingpin to rear axle rule on the longest trailers. Weight runs on a single axle limit, a tandem limit, a gross limit, and the federal bridge formula, and the formula can force you below the flat numbers.
Every figure comes from the dimensional and weight statute, and the sourced table on this page prints each one with the subsection it belongs to.
Single-trip permits and how the fee stacks
One permit covers one one-way trip, and it runs for a handful of days with a possible one-day extension for hazardous road conditions or a breakdown, requested before the permit expires. A vehicle that is both oversize and overweight gets one permit at the higher base fee, and the excess charges apply on top of it.
The stack is what surprises people. A base fee sets the floor, per-foot charges apply past a published width line and past published length lines, and excess weight is charged per increment over the axle or gross limit, whichever is greater. Every transaction then adds a flat charge plus a percentage service charge, which is why the guidebook prints round totals rather than the rule's component figures. The sourced schedule on this page carries each component.
Escort requirements
Escorts phase in by width and by length, with a second step in each dimension that takes an escort front and rear. Placement depends on the road: below four lanes the single escort leads, at four lanes or more it follows. A move running at night under a written waiver picks up an extra escort, and the guidebook states a flat count for that case which is higher than the rule's incremental wording reads on its face. Plan on the guidebook number and confirm the count printed on your permit.
Height works differently here. Passing the height line adds no escort. Instead the permittee has to notify every utility company and every county and municipal traffic engineering department controlling overhead wires, cables, signals, and bridges along the route, and the permit is void if those notifications are not made or the recommendations are not followed.
New Jersey assigns only private escorts, sets no certification requirement, and limits neither the size nor the type of escort vehicle. Spacing, warning signs, flags, and lamps all have published specifications on this page.
When a permitted load can move
The night rule splits by permit type. An oversize permit is not valid between sunset and sunrise, and the Chief Administrator may waive that in writing where it would cut congestion, where the applicant shows a business hardship, or in an emergency, with the waiver request filed alongside the application. An overweight permit for a load inside legal dimensions is valid around the clock.
Holidays close the oversize side on the major ones, with two of them extended back to the preceding Friday and one to the preceding Wednesday. A holiday falling on a weekend shifts the restriction to the adjacent weekday.
Two honest gaps. New Jersey publishes no statewide curfew list, only the conditions printed on the individual permit. It publishes no wind rule either. What it does publish is unconditional on the oversize side: no move when daylight visibility drops below a published distance, none in hazardous road conditions, none where the clear space left for passing traffic is under a published width, and none after dark by a vehicle that cannot hold a published speed.
There is no superload class
The name misleads. New Jersey's permitting system is called SUPERLOAD, but that is software, not a load category, and the state publishes no superload weight or dimension threshold. The program issues ordinary oversize and overweight permits and the annual container permit.
Heavy and wide moves are controlled by review of the route instead. A single-trip application is rejected where the load and axle configuration overstress a structure on the proposed route, and the applicant then shifts weight, changes axle spacing, or takes a different road with help from the structural engineering bureau. An overweight permit is also void if the vehicle is not already registered at the maximum weight the registration statute allows, and void if the load exceeds the published tire loading, so a light registration cannot be bought out of with a permit.
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 New Jersey without an oversize permit?
- Anything inside the statutory limits for width, height, length by configuration, axle weight, and gross weight. Width is the one that changes underneath you: the wider allowance applies on the designated truck route networks and drops elsewhere. The sourced limits table on this page carries each figure.
How much does a New Jersey single-trip permit cost?
- It stacks rather than sitting at one price: a base fee, per-foot charges past the published width and length lines, a per-increment charge on excess weight, then a flat transaction fee and a percentage service charge on the total. The sourced fee schedule on this page lists every component.
When does an oversize load need an escort in New Jersey?
- Once it passes the published width or length line, with a second step in each dimension that takes an escort front and rear. Night movement under a waiver adds another. Height adds no escort at all; it adds a notification duty to every utility and traffic engineering office along the route. The sourced table carries each threshold.
What counts as a superload in New Jersey?
- Nothing does. The state publishes no superload class or threshold, and SUPERLOAD is the name of the permitting system rather than a category of load. Heavy moves are handled by structure review of the route you propose, and a rejected route names the structures that failed.
Can an oversize load move at night in New Jersey?
- Only under a written waiver. An oversize permit is not valid from sunset to sunrise, and the waiver request has to accompany the permit application. An overweight permit for a load inside legal dimensions is valid at any hour. Night movement under a waiver also raises the escort count.
