Understanding the verdict

How to read the legal/illegal result and the slide-to-legal fix.

The verdict badge

At the top: LEGAL or NOT LEGAL, the jurisdiction (e.g. US-FED, CA-MOU), and the gross vehicle weight.

The axle bars

One bar per axle group — steer, drive tandem, trailer tandem (and gross). Each shows the group's weight against its limit. Green means within limit; red means over. A group can be over even when your gross weight is fine — that's exactly what the bridge formula catches.

The slide-to-legal fix

If the trailer tandem is over, LoadLegit computes the precise tandem slide — how many holes to move the slider, and which direction — to shift weight between the drive and trailer groups until both are legal. No guesswork at the scale.

On California loads, the fix respects the 40-ft kingpin-to-rear-axle (KPRA) limit — sliding is constrained so you don't fix one violation and create another.

Advisories (Canada)

Canadian province checks may add advisories — non-blocking notes like Quebec's spring-thaw restrictions or Ontario SPIF configurations. They never flip the verdict; they flag things to confirm locally. See State & Canada rules.
