Features

Read full description

TandemSlide Pro is a weight compliance tool for commercial drivers. Scan scale tickets, split axle weights, and see legal limits for the state you are in. Use it at the scale to decide how far to slide tandems, how much fuel to take, and whether you are legal on steer, drive, trailer, and gross. Guest mode works with no email. Sign in is optional for support. Premium is a low-cost subscription that unlocks unlimited tickets and tools. Restore Purchases is on the paywall. This app is a helper. It is not a substitute for posted signs, permits, or your own judgment.
