Truck Weigh Stations in Pennsylvania: Locations and Tips
Pennsylvania operates 47 truck weigh stations across major highways including I-81, I-80, I-76, and I-84, with most stations open 24/7 during peak travel periods. All commercial vehicles over 26,000 pounds GVWR must stop when signs indicate the station is open. The state uses PrePass and NORPASS bypass systems, allowing qualified carriers to bypass stations at highway speeds when their transponder flashes green.
Major Pennsylvania Weigh Station Locations
Interstate 81 has 8 weigh stations running north-south through Pennsylvania. The busiest locations include Carlisle (mile marker 44), Pine Grove (mile marker 100), and Wilkes-Barre Township near Pittston (mile marker 170). These stations handle the heaviest truck traffic between New York and the Southeast.
Interstate 80 operates 12 weigh stations across the state, with major facilities at Clarion (mile marker 62), Lamar (mile marker 173), and Delaware Water Gap (mile marker 310). The Pennsylvania Turnpike (I-76) maintains 15 weigh stations, including large facilities at New Stanton, Carlisle, and King of Prussia.
Interstate 84 has 3 weigh stations in northeastern Pennsylvania, with the primary facility at Matamoras near the New York border. This station processes trucks entering Pennsylvania from New Jersey and New York.
When Must You Stop at Pennsylvania Weigh Stations?
All commercial vehicles exceeding 26,000 pounds GVWR must stop when electronic signs display "All Trucks Must Stop" or similar messaging. Pennsylvania law requires stops regardless of actual load weight - the requirement is based on vehicle registration weight, not current cargo.
Vehicles pulling trailers, even pickup trucks with heavy trailers, must stop if the combined weight exceeds 26,000 pounds. Pennsylvania State Police enforce weigh station compliance and can issue citations up to 5 miles past a station if you failed to stop when required.
Rental trucks, RVs over 26,000 pounds, and farm vehicles during commercial use must also comply with weigh station requirements. The "commercial use" determination depends on cargo type and trip purpose, not vehicle ownership.
How Pennsylvania's Bypass Programs Work
PrePass and NORPASS transponders allow qualified carriers to bypass stations when their device flashes green and beeps twice. Pennsylvania participates in both programs, with over 85% of the state's weigh stations equipped with bypass technology.
To qualify for bypass programs, carriers must maintain good safety scores, current registration, and clean inspection records. The system automatically checks your DOT number, safety rating, and recent violation history as you approach each station.

What Happens During a Weigh Station Stop?
Most weigh station stops take 3-5 minutes for weight verification only. Pull onto the scale slowly, stop when directed, and wait for the green light before proceeding. Keep your logbook, registration, and medical card easily accessible.
Pennsylvania uses static scales that measure individual axle weights and gross vehicle weight simultaneously. Officers can see your weights immediately and will signal you to proceed if everything checks out. Overweight violations result in immediate citations and potential out-of-service orders.
Random DOT inspections occur at approximately 15% of weigh station stops. Level 1 inspections take 45-90 minutes and include driver qualification checks, hours of service review, and complete vehicle inspection. Level 2 inspections focus on driver credentials and take 15-30 minutes.
Pennsylvania Weight Limits and Fines
Pennsylvania allows 80,000 pounds gross vehicle weight on interstate highways, with 34,000 pounds maximum on tandem axles and 20,000 pounds on single axles. Steering axle weight cannot exceed 12,000 pounds under state law.
Overweight fines start at $75 for violations up to 1,000 pounds over limit. Fines increase dramatically for larger overages: 5,000-10,000 pounds over results in $525 fines, while 15,000+ pounds over can cost $1,200 or more. Severe overweight violations may require immediate load adjustment or escort permits.
| Weight Over Limit | Fine Amount |
|---|---|
| 1-1,000 lbs | $75 |
| 1,001-2,000 lbs | $150 |
| 5,001-10,000 lbs | $525 |
| 15,001+ lbs | $1,200+ |
Tips for Smooth Weigh Station Experiences
Approach weigh stations at 25-30 mph maximum and follow posted signs directing truck traffic. Many Pennsylvania stations have separate lanes for different vehicle types - choose the correct lane to avoid delays.
Keep required documents in a folder within arm's reach: current registration, medical card, logbook or ELD display, and driver's license. Officers appreciate organized drivers who can quickly provide requested documentation.
If selected for inspection, park in designated areas and remain with your vehicle unless instructed otherwise. Turn off your engine during inspections to reduce noise and allow clear communication with officers. Cooperative drivers typically receive faster, more thorough inspections.
