New Jersey Weigh Stations and Bypass Program Operations

Commercial vehicle operations in New Jersey are governed by the New Jersey Department of Transportation (NJDOT) and the New Jersey State Police (NJSP) Transportation Safety Bureau. All commercial vehicles with a Gross Vehicle Weight Rating (GVWR) of 10,001 pounds or more are required to pull into open weigh stations. These facilities, often referred to as 'scales,' are strategically placed along major freight corridors like I-295, I-78, and I-80 to ensure compliance with the bridge formula and safety standards. Drivers failing to stop at an open station face significant fines and potential out-of-service orders under NJSA 39:3-84.3. DispatchTool assists carriers navigating these high-enforcement corridors by providing truck-safe routing that accounts for New Jersey’s complex restriction zones and weight limits. The platform integrates with fleet workflows to manage the documentation required for roadside inspections, such as BOLs and IRP credentials. To improve your route planning and compliance tracking across the Northeast, you can create a DispatchTool account.

Primary Weigh Station Locations and Hours

New Jersey operates several permanent weigh station facilities, primarily concentrated near its borders and major industrial hubs. Key locations include the I-295 Northbound station in Carney's Point (Milepost 4.5) and the I-78 Eastbound station in Greenwich (Milepost 5.5). Unlike some western states, New Jersey stations do not follow a fixed 24/7 schedule but operate based on NJSP enforcement details. The I-80 Eastbound scale in Knowlton (Milepost 1) is a frequent site for Level I North American Standard Inspections. Carriers should also be aware of portable scale operations conducted by the NJSP Mobile Commercial Vehicle Enforcement units, which can set up at rest areas or wide shoulders at any time.

New Jersey Legal Weight Limits and Axle Spacing

New Jersey enforces a maximum gross vehicle weight of 80,000 pounds on the Interstate System and other designated highways without a special permit. Single axle limits are set at 22,400 pounds, while tandem axles are restricted to 34,000 pounds. The state utilizes the Federal Bridge Formula B to determine weight allowances for shorter wheelbase vehicles. For non-interstate highways, New Jersey statutes allow for slightly different tolerances, but any vehicle exceeding 5% of its registered weight or the statutory limit is subject to offloading requirements. Fines for overweight violations scale based on the degree of excess, often exceeding $500 for the first 1,000 pounds over the limit.

PrePass and E-ZPass Bypass Integration

New Jersey is a participating member of the PrePass bypass system, allowing qualified carriers to bypass scales at a rate determined by their Safety Measurement System (SMS) scores. The I-295 Carney's Point and I-78 Greenwich sites are equipped with PrePass transponder readers. When the transponder signals a green light, the driver is cleared to bypass; a red light requires an immediate pull-in. It is important to note that New Jersey's E-ZPass system, while used for tolling on the NJ Turnpike and Garden State Parkway, does not function as a weight station bypass signal. Drivers must ensure they have a dedicated weigh station bypass service active to avoid unnecessary stops.

Oversize and Overweight (OS/OW) Permit Requirements

Vehicles exceeding 13 feet 6 inches in height, 8 feet 6 inches in width, or 80,000 pounds in weight must obtain a hauling permit from the NJDOT Bureau of Motor Carrier Services. Single-trip permits generally cost $10 plus a weight-based fee, such as $2.10 per ton for every ton over the legal limit. For loads exceeding 150,000 pounds, a superload permit is required, which involves a specific bridge structural analysis that can take up to 10 business days. New Jersey also enforces strict 'Travel Time' restrictions for OS/OW loads, generally prohibiting movement during peak commuter hours (6:30 AM to 9:00 AM and 4:00 PM to 6:00 PM) in metropolitan areas.

Commercial Vehicle Inspection Standards

The NJSP conducts inspections following the Commercial Vehicle Safety Alliance (CVSA) guidelines. A Level I inspection covers 37 steps, including a detailed look at the braking system, lighting, and coupling devices. In 2023, the most common out-of-service violations in New Jersey were related to brake adjustment and tire tread depth (less than 2/32 inch on rear tires or 4/32 inch on steer tires). Drivers should maintain an organized permit book and electronic logging device (ELD) records to minimize time spent at the scale. The FMCSA reports that New Jersey conducts over 40,000 roadside inspections annually, maintaining one of the highest enforcement densities in the United States.

Frequently asked

What is the fine for bypassing a weigh station in New Jersey?

Under NJSA 39:3-84.3, failure to stop for a directed weight check can result in a fine of $100 to $200 for a first offense, plus court costs. Repeated violations or attempting to evade a mobile unit can lead to higher penalties and increased SMS scores for the carrier.

Do empty trucks have to stop at NJ scales?

Yes, all commercial vehicles with a GVWR over 10,000 pounds must enter an open weigh station, regardless of whether they are loaded or empty, unless they receive a bypass signal from a recognized electronic system.

Where is the I-295 weigh station located?

The primary I-295 weigh station is located Northbound at Milepost 4.5 in Carney's Point, near the Delaware Memorial Bridge. It is a major entry point for freight moving from the south into the New Jersey/New York corridor.

Does New Jersey allow a weight tolerance?

New Jersey law generally allows a 5% tolerance on registered weight for certain commodities, but this does not override the 80,000-pound federal bridge limit on Interstates. Exceeding the bridge limit by even 500 pounds can result in a citation.
