Direct answer: New Jersey has five fixed NJSP weigh station facilities — on I-78 (both directions, MP 6, Warren County), I-295, I-287, and I-80 — plus two roving weight teams that patrol Port Newark exit corridors. The legal GVW limit is 80,000 lbs with zero tolerance under NJSA 39:3-84. Fines start at $500 for the first 1,000 lbs over GVW and climb from there. If your container is sealed and between 80,001 and 90,000 lbs, an Annual Ocean Container Permit through NJDOT SUPERLOAD is your legal path. Above 90,000 lbs, or if axles are unbalanced regardless of total weight, restack or split the load before you hit the highway.
Why Port Newark Drayage and NJ Weight Enforcement Are on a Collision Course
The scale of the problem: 8.9 million TEUs and 85% moving by truck
The Port of New York and New Jersey handled 8.9 million TEUs in 2025. Approximately 85% of that volume moves by truck within roughly 250 miles of port facilities. Every chassis leaving Port Newark Container Terminal, Elizabeth Marine Terminal, or Global Container Terminal has to enter a New Jersey highway to go anywhere.
Weight enforcement does not care about volume. The state has five fixed scale installations and two roving teams. The density of port truck traffic increases enforcement contact probability because NJSP Commercial Carrier Safety Inspection Unit personnel concentrate roving deployments on freight corridors — and those corridors all originate at the port.
See our coverage of Port Newark freight corridor congestion and enforcement exposure for additional operational context.
Why heavy containers are structurally more common at Port Newark than inland depots
Dense import surges compound the problem. When importers frontload cargo to beat tariff increases, they pack containers harder. The post-tariff container backlog at Port Newark has produced a sustained run of containers loaded at or past legal limits. A shipper in Guangdong is not thinking about NJSA 39:3-84 when stuffing a box. The drayage carrier who picks it up at the gate is the one who finds out at the scale.
The NJ Enforcement Architecture: NJSP CCSIU, Five Fixed Scales, and Two Roving Teams
Five fixed scale facilities and where they sit relative to port exit routes
The NJSP Commercial Carrier Safety Inspection Unit operates five fixed weigh station facilities across New Jersey. The NJSP CCSIU page lists the following active scale locations:
- Greenwich Scales — I-78, MP 6, Greenwich Township, Warren County
Eastbound: 908-479-1842 / Westbound: 908-479-6829 - Knowlton Scale — I-80 EB, MP 2.3, Knowlton Township, Warren County
908-496-4896 - Piscataway Scale — I-287 NB, MP 9.3, Piscataway Township, Middlesex County
732-885-1539 - Carneys Point Scale — I-295 NB, MP 3.5, Carneys Point Township, Salem County
856-351-9112 - Springfield Rest Area — I-295 NB, MP 49.9, Springfield Township, Burlington County
Every practical exit route from Port Newark leads toward at least one of these facilities. There is no enforcement-free corridor out of the port — that is geography, not conjecture.
For official scale locations, see the NJSP Commercial Carrier Safety Inspection Unit — official scale locations.
WIM pre-screening: how weigh-in-motion decides which trucks stop
Before a truck reaches the static scale, it passes over weigh-in-motion (WIM) sensors embedded in the road surface. These sensors read gross weight and per-axle weights at normal highway speed. Any commercial motor vehicle suspected of exceeding limits is directed to the static scale for a full static measurement.
Once confirmed overweight on the static scale, CVSA inspection protocol applies: brakes, tires, lighting, HOS records, credentials. A CMV confirmed in violation of size and weight regulations is subject to a full CVSA inspection per NJSP CCSIU enforcement guidelines.
Definition — Weigh-In-Motion (WIM) Pre-Screening: A roadway sensor system that measures dynamic axle loads and estimated gross weight of a moving vehicle without requiring it to stop. In New Jersey, WIM data pre-selects trucks for static scale inspection. A WIM flag does not constitute a violation — a static scale confirmation does.
Roving weight teams and mobile portable scales
Fixed stations are not the whole picture. NJSP CCSIU deploys two roving weight enforcement teams statewide, each equipped with portable scales. These teams are not random — they work freight corridors, and the corridor running from Port Newark and Elizabeth Marine Terminal toward I-78, I-287, and the Turnpike is one of the highest-volume commercial truck corridors in the country. Taking surface roads to skip fixed stations does not mean reduced exposure; it may mean driving directly into a portable scale operation.
The Route-by-Route Exposure Map for Port Newark Carriers
I-78 westbound: the direct port exit and the Greenwich scale
I-78 westbound is the most direct route west from Port Newark and Elizabeth for carriers heading into Pennsylvania, the Lehigh Valley, or central and western New Jersey distribution points. It runs straight into the I-78 Greenwich Scales at milepost 6 in Warren County, with active eastbound and westbound facilities at that location. There is no alternate westbound I-78 path that avoids this scale. By the time most drivers recognize the scale approach, they are committed.
NJ Turnpike (I-95) northbound and southbound: enforcement through corridor concentration
The NJ Turnpike has no fixed weigh station. What it has is heavy NJSP CCSIU roving patrol concentration, consistent with the state's Commercial Vehicle Safety Plan, which identifies the Turnpike among the primary CMV corridors for saturation patrol deployment. The absence of a fixed facility does not mean reduced enforcement — it means less predictability, which is operationally worse for carriers trying to plan around it.
I-287 corridor: Piscataway scale and the ring-road trap
I-287 functions as a ring road connecting the port area to northern and central New Jersey distribution points. The Piscataway fixed scale sits on this corridor at MP 9.3. Carriers using I-287 to avoid I-78 or the Turnpike are not avoiding enforcement — they are trading one fixed scale for another. The pattern across all three primary port exit corridors is consistent: fixed or roving enforcement contact is a near-certainty for overweight vehicles.
For a fuller operational picture of these corridors, see our piece on Port Newark freight corridor congestion and enforcement exposure.
New Jersey's Legal Weight Limits: Every Number a Drayage Driver Needs
Gross vehicle weight, single axle, tandem axle, and bridge formula
New Jersey's weight limits under NJSA 39:3-84:
- Gross Vehicle Weight (GVW): 80,000 lbs maximum
- Single axle: 22,400 lbs maximum
- Tandem axle: 34,000 lbs maximum
- Width: 8'6" (102 inches) on interstates and the NJ 102" truck route network; 8' on other highways
- Height: 13'6" maximum on all highways
- Overall length (tractor-semitrailer combination): 62 feet maximum
New Jersey enforces zero tolerance on these limits. There is no grace percentage, no fixed-pound buffer, no informal threshold. Zero tolerance means exactly that.
Beyond the flat limits, the federal bridge formula governs how much weight can be placed across axle groups based on axle spacing. A truck with a legal GVW and legal per-axle weights can still fail the bridge formula if axle spacing does not adequately distribute load across the combination.
Dimensional limits: width, height, length
Most port drayage combinations run standard 40-foot or 45-foot containers on chassis, so dimensional violations are less common than weight violations. High-cube containers on certain chassis configurations can approach the 13'6" height limit. Know your loaded height before you roll, particularly on routes with overhead clearance constraints.
Why a truck can be under 80,000 lbs GVW and still be in violation
This is the one that catches drivers off guard. A truck running 78,000 lbs GVW is legal on gross weight. But if the cargo is loaded so that one tandem axle group carries 38,000 lbs, that axle is 4,000 lbs over the 34,000-lb tandem limit — and that is a citable violation regardless of what the gross weight shows.
WIM sensors read individual axle weights, not just total gross. The static scale confirms what the WIM flags. Uneven load distribution inside the container — freight packed heavy toward one end, or a dense pallet group concentrated over one axle — is the most common source of axle violations on otherwise compliant loads.
What a Stop Actually Costs: Fines, CSA, and Detention Time
The fine math under NJSA 39:3-20.3 and NJSA 39:3-84.3
GVW overweight fines under NJSA 39:3-20.3: $500 for the first 1,000 lbs over the limit, then $100 for each additional 1,000 lbs. A truck running 90,000 lbs on an 80,000-lb limit — a 10,000-lb overage — triggers a $1,400 fine. That is the base fine before contested legal fees, driver detention time, or CSA consequences.
Axle-weight fines under NJSA 39:3-84.3: $0.02 per pound for the first 10,000 lbs of excess, $0.03 per pound beyond that, with a $50 minimum.
Under NJSA 39:3-84.3(j), when the overweight vehicle is carrying a sealed ocean container, the shipper, the consignee, or both may also be held liable in addition to the carrier. Most shippers are unaware of this provision. Carriers who document verified cargo weight from the shipper before accepting dispatch have both a pre-departure safeguard and evidence for liability recovery if needed.
The violation records permanently on the driver's NJ record. An out-of-service order grounds the truck at the scale until violations are corrected — no legal departure until NJSP clears the vehicle.
For detail on how overweight delays compound into detention billing exposure, see our breakdown of FMC §541 detention billing and how overweight delays compound costs, and our operational guide to NJ axle weight compliance and overweight load correction.
CSA score impact and carrier safety rating consequences
A weight violation at a fixed scale or roadside inspection triggers an FMCSA CSA record entry under the Vehicle Maintenance BASIC category. Carriers accumulating points toward an alert threshold face increased inspection scrutiny on every subsequent stop — which increases the probability of additional violations being found. A single overweight load at the wrong time can push a small fleet carrier into alert status.
Dwell time: what sitting at a scale means for HOS and customer SLAs
An OOS order can mean four to eight hours of dwell time before a tow or on-site load correction can be arranged. That burns HOS. A driver with a tight clock before hitting the scale may run out of available hours at the facility — triggering an HOS violation on top of the weight citation. The customer's delivery appointment is gone. Chassis free time continues to run. The costs stack.
The Ocean Container Annual Permit: What It Covers and What It Does Not
N.J.A.C. 13:18-1.2(c): the 90,000-lb sealed container permit explained
New Jersey has a legal pathway for sealed containers that exceed 80,000 lbs. Under N.J.A.C. 13:18-1.2(c), NJDOT issues an Annual Ocean Borne Containerized Cargo Multiple-Trip Permit allowing GVW up to 90,000 lbs for sealed containers bearing a U.S. Customs, government, or shipper seal. The base permit fee is $100 per year, plus a $12 transaction fee and a 5% service charge. Apply through NJDOT SUPERLOAD, which is available 24/7. Permit inquiries: 609-963-2085.
This is a legitimate, legal option for containers between 80,001 and 90,000 lbs. It is underused. Many carriers either do not know it exists or assume the process is slower than it is. The SUPERLOAD system is online around the clock and turnaround is faster than most dispatchers expect.
Tandem axle limits under the permit and why they still bite carriers
The permit raises the GVW ceiling to 90,000 lbs but does not eliminate axle-weight requirements. Under the Annual Ocean Container Permit, the tandem axle limit increases to 38,000 lbs (versus 34,000 lbs standard) and the tri-axle limit is 56,400 lbs. The load still has to be distributed correctly across axle groups to stay within those numbers. A container with uneven internal load distribution can produce a tandem axle violation even with the permit in hand. The permit does not fix bad weight distribution inside the box.
Critical additional point: the NJ Turnpike and Garden State Parkway require separate authority permits in addition to the Annual Ocean Container Permit. Factor that into permit planning before dispatch if your route uses either road.
NJDOT SUPERLOAD system and how to apply
Go to nj.gotpermits.com. Create or log into your account and select the Annual Ocean Borne Containerized Cargo Multiple-Trip Permit. You will need the vehicle configuration, registered GVW, axle weights, and the nature of the seal on the container. The $100 annual fee plus transaction charges is negligible relative to a single $1,400 GVW fine, and the permit covers unlimited trips for the calendar year once issued.
The Cross-Dock Solution: Why Diverting Before the Scale Is Faster and Cheaper
The math: fine + delay + CSA impact vs. a restack at RapidShips
| Option | Risk Level | Fine Exposure | CSA Impact | Delay | True Cost |
|---|---|---|---|---|---|
| Drive as-is (overweight) | HIGH | Up to $1,400+ GVW or $0.03/lb axle | YES — permanent record entry | Unpredictable; OOS possible, 4–8 hrs dwell | Cheapest upfront / most expensive total |
| Annual Ocean Container Permit (sealed, ≤90,000 lbs, axles in spec) | LOW | $0 if fully compliant | NO | 24/7 online via NJDOT SUPERLOAD | $100 + $12 transaction fee + 5% service charge |
| Cross-dock restack or load split at RapidShips | NONE | $0 | NO | Controlled; same-day redispatch | Rework fee vs. fine + legal + detention + CSA |
What RapidShips does: repalletize, restack, split-load, and redispatch 24/7
RapidShips operates a 24/7 dock at 25A Cotters Lane in East Brunswick, NJ. When a carrier brings in an overweight or axle-unbalanced container, we unload it, repalletize or restack the freight to achieve proper axle weight distribution, and — where total load exceeds 80,000 lbs without a permit pathway — split it into two compliant moves. The truck leaves legal: no scale contact, no fine, no CSA entry, no OOS order.
If the issue is load shift inside the container — cargo that moved in transit and is now front-heavy or rear-heavy — we can redistribute that too. See our guide on what to do when a load has shifted or is unevenly distributed, along with our pages on freight rework and load repalletization to restore compliance and cross-docking and transloading options near Port Newark.
How the East Brunswick location puts RapidShips between the port and every enforcement corridor
East Brunswick sits on Route 18, inside the zone between Port Newark and every major highway enforcement corridor heading west, south, and north. A carrier diverting to our facility before hitting I-78, I-287, or the Turnpike eliminates enforcement exposure before reaching any scale. The alternative is discovering the problem at the scale — the worst possible place to discover it.
We match port gate hours because that is when the calls come in. A container does not stop being heavy at midnight.
Dispatcher's Quick-Decision Checklist Before Rolling a Heavy Container
Step 1: Know the container weight before the gate appointment
Get the verified cargo weight and container tare weight before your driver goes to the gate. The shipper's VGM (Verified Gross Mass) documentation is the starting point. Tare weight is on the container door placard. Add those numbers. If the total approaches 80,000 lbs before accounting for chassis, fuel, and driver weight, you have a potential problem — and you need to know that before the gate appointment, not after.
For planning around gate appointment timing and chassis availability, see our guide on container gate appointments and chassis availability at Port Newark.
Step 2: Calculate axle distribution, not just GVW
Total weight is one number. Axle distribution is a separate calculation. A standard 5-axle combination (tractor with steer axle, dual drive tandems, and a 2-axle chassis) distributes weight across three axle groups. If cargo is packed unevenly, one group carries a disproportionate share. You can be 5,000 lbs under GVW and still have a tandem axle violation. Know where the freight sits in the container and estimate which axle group it loads.
Step 3: Permit, restack, or split — choose before you roll
- Under 80,000 lbs GVW with balanced axle distribution: Proceed. Legal under NJSA 39:3-84.
- 80,001 to 90,000 lbs GVW, sealed container, axles within permit limits: Obtain the Annual Ocean Borne Containerized Cargo Multiple-Trip Permit through NJDOT SUPERLOAD (nj.gotpermits.com, 609-963-2085) before dispatch. Cost is $100 plus fees. Do not roll without it. If your route uses the NJ Turnpike or Garden State Parkway, obtain those separate authority permits as well.
- Over 90,000 lbs GVW, or any weight with axles confirmed out of spec: Call RapidShips at 800-376-2808 before dispatch. Divert to 25A Cotters Lane, East Brunswick. Same-day restack, repalletization, or load split before any highway enforcement contact.
Making this decision at the dispatcher's desk costs nothing. Making it at the scale costs $1,400 minimum — before everything that comes after.
Frequently Asked Questions
Where exactly is the I-78 weigh station that affects Port Newark drayage carriers?
The I-78 Greenwich Scales are at milepost 6 in Greenwich Township, Warren County. The eastbound facility number is 908-479-1842; westbound is 908-479-6829. Both are operated by NJSP CCSIU. Any carrier leaving Port Newark or Elizabeth heading west on I-78 will encounter this station. There is no alternate westbound I-78 route that avoids it.
What are New Jersey's truck weight limits for a standard drayage combination?
Under NJSA 39:3-84: 80,000 lbs GVW maximum, 22,400 lbs per single axle, 34,000 lbs per tandem axle, 13'6" height, 8'6" width on interstates, and 62-foot maximum overall length for a tractor-semitrailer combination. New Jersey enforces zero tolerance on all of these. If the static scale reads over the limit, it is a violation.
Can I haul a sealed ocean container heavier than 80,000 lbs in New Jersey?
Yes. Under N.J.A.C. 13:18-1.2(c), NJDOT issues an Annual Ocean Borne Containerized Cargo Multiple-Trip Permit allowing up to 90,000 lbs GVW for sealed containers, with a tandem axle ceiling of 38,000 lbs and tri-axle max of 56,400 lbs. The permit costs $100 plus a $12 transaction fee and 5% service charge. Apply through NJDOT SUPERLOAD at nj.gotpermits.com. The NJ Turnpike and Garden State Parkway require separate authority permits.
Who is responsible for the fine if a sealed ocean container makes a truck overweight?
Under NJSA 39:3-84.3(j), when a vehicle carries a sealed ocean container, the shipper, the consignee, or both may be held liable for the overweight violation in addition to the carrier. Require verified cargo weight documentation from the shipper before accepting the load. That documentation is also your evidence if you need to pursue liability recovery after a fine.
What happens operationally when a truck is pulled into a NJ weigh station?
WIM sensors read axle and gross weights at highway speed. Trucks flagged as suspected overweight are directed to the static scale. A confirmed overweight CMV is subject to a full CVSA Level I inspection — brakes, tires, lighting, HOS records, credentials. An out-of-service order grounds the truck at the station until violations are corrected. The driver cannot legally depart until NJSP clears the vehicle.
Why is diverting to a cross-dock faster than contesting an overweight citation?
A NJ GVW overweight citation is permanent on the driver's record. A 10,000-lb excess generates a $1,400 base fine under NJSA 39:3-20.3 before legal fees. An OOS order adds hours of dwell and burned HOS. A same-day restack or load split at RapidShips in East Brunswick — 800-376-2808 — eliminates the violation before any enforcement contact, keeps the CSA score clean, and keeps the truck moving the same day.
Bottom Line
New Jersey weight enforcement out of Port Newark is not a risk you can route around. Five fixed scale installations, two roving teams, and WIM pre-screening on every major freight corridor mean an overweight container will almost certainly face enforcement contact. The fine structure is steep, the record is permanent, and an OOS order can strand a driver for the better part of a workday.
The decision has to be made before the gate appointment. Know your weight, calculate your axles, get the permit if you qualify, and if the numbers do not work, call before you roll.
