TandemSet

Know your tandem setting before you roll. Select your states, get the answer instantly.

TandemSet is built for truck drivers who need to know their kingpin-to-rear-axle setting before they hit the road.

Select every state on your route and TandemSet instantly shows you the most restrictive bridge law across all of them — so you're always legal, no matter where you roll.

Running through Texas, California, and Oregon? California's 40 ft limit is the most restrictive — TandemSet tells you that immediately, so you set your tandems once and drive with confidence.

Enter your current tandem setting and see if you're compliant, or exactly how far you need to slide.

Fully offline. No account. No network required. Built for one-handed use on the road.
