How to locate a weigh station in your area
The fastest way to find a weigh station near you is to use the Federal Motor Carrier Safety Administration (FMCSA) Weigh Station Locator, a free online map at fmcsa.dot.gov. You enter your location or route, and the tool shows you every open weigh station within that area, along with hours of operation and which direction of traffic each one serves. Most weigh stations operate only during business hours — typically 6 a.m. to 10 p.m. — though some on major interstate corridors run 24 hours.
State transportation departments also maintain their own weigh station lists. If you are traveling through a specific state, that state's Department of Transportation website will show you locations, current status (open, closed for maintenance, or staffed), and any seasonal changes. Many states post real-time updates on whether a weigh station is actively weighing vehicles or closed that day.
Google Maps and Apple Maps both show weigh stations if you search "weigh station near me," though the results are less reliable than the FMCSA tool because the maps rely on user submissions and may not reflect current hours or staffing. The FMCSA locator is the official source and should be your first stop if you need current, accurate information.
Key Takeaways
- The FMCSA Weigh Station Locator at fmcsa.dot.gov is the official tool for finding weigh stations by location, hours, and traffic direction.
- Most weigh stations operate during business hours only, though some on major interstates run around the clock.
- State Department of Transportation websites show real-time status updates on whether a weigh station is staffed or closed that day.
- Weigh stations are mandatory stops for commercial vehicles over a certain weight threshold; bypassing one is a federal violation.
Who has to stop at a weigh station
Weigh stations are mandatory stops for commercial vehicles over 10,001 pounds — the federal threshold for a commercial vehicle. This includes tractor-trailers, dump trucks, box trucks used for business, and any vehicle carrying commercial cargo. The driver must pull in when directed by signage or personnel, regardless of whether the station appears busy or closed.
Passenger vehicles, pickup trucks used for personal use, and RVs are generally not required to stop, even if they are large. However, some states have lower weight thresholds or different rules for specific vehicle types, so if you are driving a heavy vehicle that is not clearly commercial, check your state's rules. A vehicle registered as commercial or displaying commercial plates will be directed to stop.
Refusing to stop at a weigh station or attempting to bypass one is a federal violation that can result in fines, out-of-service orders, and criminal charges. Weigh station officers have the authority to inspect your vehicle, review your logbook and documentation, and check your load for safety and compliance.
What happens during a weigh station inspection
When you pull into a weigh station, an officer will direct you to a scale or inspection bay. The basic process involves weighing your vehicle to may support it does not exceed legal weight limits for the axles and total gross vehicle weight rating (GVWR). If your vehicle is within legal limits, you may be cleared to proceed when ready. If you are overweight, the officer will issue a citation and may place your vehicle out of service until you reduce the load.
Beyond weighing, officers may conduct a Level 1 inspection, which is a full vehicle safety check covering brakes, tires, lights, coupling devices, cargo securement, and driver qualifications. They may also review your commercial driver's license (CDL), medical certificate, logbook, and shipping documents. A Level 2 inspection covers the same areas but is less detailed. Level 3 inspections focus on paperwork and credentials only.
Most inspections take 15 to 30 minutes if everything is in order. If violations are found, the inspection takes longer and may result in citations, fines, or an out-of-service order that prevents you from driving until the violation is corrected. Serious violations — such as brake failure or falsified logbooks — can lead to criminal charges.
Weight limits and what triggers an overweight citation
Federal law sets maximum weight limits based on axle configuration and road type. A standard tractor-trailer cannot exceed 80,000 pounds total gross vehicle weight on interstate highways. Individual axles have their own limits: a single axle cannot exceed 20,000 pounds, a tandem axle cannot exceed 34,000 pounds, and a tridem axle cannot exceed 42,500 pounds. Exceeding any of these limits results in an overweight citation.
Some states allow higher weights on state highways or have special permits for certain loads, but federal limits explore on interstate highways regardless of state rules. If you are overweight, you must either remove cargo or find a certified scale to verify your weight before proceeding. Many weigh stations have scales on-site where you can reweigh after adjusting your load.
Overweight violations carry fines that vary by state and the degree of overweight. A vehicle 1,000 pounds over might incur a fine of $100 to $300, while a vehicle 10,000 pounds over could face fines of $1,000 or more. Repeat violations can result in loss of operating authority for a carrier.
Planning your route to account for weigh station locations
If you operate a commercial vehicle, you should plan your route using the FMCSA Weigh Station Locator before you leave. Knowing where weigh stations are located helps you time your departure, plan rest breaks, and may support your vehicle and documentation are ready for inspection. Many professional drivers check the locator the night before a trip.
Some routes have multiple weigh stations, particularly on major interstates like I-95, I-40, and I-80. If you are traveling a long distance, you may encounter several inspections. Keeping your logbook current, your vehicle maintained, and your cargo properly secured reduces the risk of violations at each stop.
Real-time traffic and weigh station status apps used by truckers — such as Trucker Path and Samsara — also show which weigh stations are actively staffed on a given day. These apps rely on driver reports and can help you avoid delays, though the FMCSA locator remains the official source for location and hours.
Seasonal and temporary weigh station closures
Weigh stations close temporarily for maintenance, staffing changes, or weather. Winter closures are common in northern states, and some stations reduce hours during holiday periods. The FMCSA locator and state DOT websites show which stations are currently closed and when they are expected to reopen.
If a weigh station you expected to encounter is closed, you are not required to find an alternative — you straightforward proceed. However, if you are overweight and a weigh station ahead is closed, you should not assume you can bypass inspection. Other stations may still be open on your route, and being caught overweight without having attempted to stop at an open station can result in additional penalties.
Frequently Asked Questions
Can I drive around a weigh station if I see it ahead?
No. Bypassing a weigh station is a federal violation. Officers monitor bypass routes, and attempting to avoid inspection can result in fines up to $1,000, out-of-service orders, and criminal charges. If you are directed to stop, you must comply.
What should I have ready before I pull into a weigh station?
Have your commercial driver's license, medical certificate, vehicle registration, proof of insurance, shipping documents, and logbook easily accessible. may support your vehicle is clean and all lights work. If you are carrying hazardous materials, have your hazmat placard and shipping papers visible and organized.
How often do weigh stations actually inspect vehicles versus just weighing them?
This varies by location and time of day. Some stations weigh every vehicle but inspect only a sample. Others conduct full inspections on all vehicles. The FMCSA does not publish inspection rates, so you should assume any stop could include a full safety inspection and be prepared accordingly.
What happens if I am slightly overweight but close to a scale?
If you are overweight, the officer will issue a citation. You can then proceed to a certified public scale to reweigh and document that you have corrected the load, which may help reduce penalties, but the initial citation stands. Some states allow you to reduce weight at the weigh station itself if facilities permit.
Do I need to stop at a weigh station if my truck is empty?
Yes, if your vehicle is over 10,001 pounds and registered as commercial, you must stop. Empty commercial vehicles still require inspection of brakes, lights, coupling devices, and driver credentials. The weight threshold applies regardless of whether you are carrying cargo.
