New Jersey Weigh Stations & Ag Inspection

When New Jersey makes you pull in

New Jersey sends every vehicle at 10,001 lb or more across the scale when a station is open and the sign directs you in. State Police run fixed scales on I-295, I-80, I-287, and I-78, plus virtual weigh-in-motion sites and roving units. Skip an open one and you can be turned around and cited for failing to comply, a fine up to $200. The overweight ticket itself is separate and climbs with the pounds you are over (N.J.S.A. 39:3-84.3).

Stations, bypass, and inspection

• Who must stop: Over a weight threshold
• Where the stations are: Permanent scales at Carneys Point (I-295), Knowlton (I-80), Piscataway (I-287), and Greenwich (I-78), plus virtual weigh-in-motion sites and State Police roving units. Fixed stations run variable hours behind lit signs.
• Bypass: Both work here. PrePass and Drivewyze PreClear cover the same fixed scales: Carneys Point (I-295), Knowlton (I-80), Piscataway (I-287), and Greenwich (I-78). Green means bypass; red or no signal means report in.
• Ag / border inspection: No agricultural inspection stations. New Jersey enforces size and weight, not produce quarantine.
• Fine for passing an open station: Failing to stop and submit to weighing is charged as failure to comply, a fine up to $200, and officers can bring you back. The overweight ticket itself is separate and climbs with the pounds you are over (N.J.S.A. 39:3-84.3).
