CAT stands for Certified Automated Truck scales. They’re the most trusted and widely used truck weighing system in North America, with over 2,000 locations across the U.S. and Canada.
CAT scales are independently owned and operated at travel centers, truck stops, and fuel stations. Unlike basic scales, CAT scales provide legally certified weights that stand up in court and meet DOT compliance requirements.
If you get an overweight fine after weighing legal on a CAT scale, the CAT Scale Company will pay the fine or appear in court with you. That’s their guarantee. No other scale company offers this.
There are several ways to locate CAT scales:
Unlike the official CAT locator, Scale Right shows scales not just near you, but along your entire route. It also tells you exactly how many miles off your route each scale is, so you can pick the closest one without guessing or backtracking.
Accepted payment methods: Visa, Mastercard, Discover, AMEX, PayPal, EFS, Comdata, QuikQ, and Relay Payments. The Weigh My Truck app adds a $1.00 transaction fee on top of the standard weigh fee.
If you slide your tandems to fix an overweight axle, the reweigh is only $5.00 at the same location within 24 hours. Always reweigh at the same CAT Scale to get the reweigh price.
This is what makes CAT scales stand out from every other truck scale. Their guarantee is simple:
If you receive an overweight fine after weighing legal on a CAT scale, the CAT Scale Company will pay the fine or appear in court with you. This applies to both printed tickets and Weigh My Truck app tickets (except California). One driver reported CAT Scale paying a $16,371 fine on his behalf in Maryland.
This is why most experienced drivers insist on CAT scales over no-name truck stop scales. The guaranteed accuracy and legal backup is worth the few extra dollars.
Scale Right has a built-in scale finder with 2,200+ locations. Find the nearest scale on your route, see the address, and navigate there in one tap.
⚖️ Weigh as close to the shipper as possible. If you’re overweight, you want to know before you’re hours down the road. Find the nearest scale right after pickup.
📱 Set up the Weigh My Truck app before you need it. Register your truck, add payment info, and download the app the night before. Saves 15-20 minutes per weigh.
📍 Use Scale Right to find the closest scale. 2,200+ locations, find scales along your route, instant tandem slide suggestions.
🔄 Always reweigh after adjusting tandems. A $5.00 reweigh is cheaper than a $1,000+ overweight fine.
🧾 Keep your tickets. The Weigh My Truck app emails PDF tickets automatically, but keep printed backups for your records.
Never drive past a weigh station wondering if you’re legal.
