Documentation
Start here
LoadLegit checks truck axle weights, centre of gravity and jurisdictional weight limits — before the truck rolls. This is the product documentation.
LoadLegit turns a load into a legal verdict: enter (or pack) a load, and it computes per-axle-group weights, gross weight, the Federal Bridge Formula and per-jurisdiction limits — then tells you the exact tandem slide if you're over. It works for the US and Canada, in imperial or metric.

What you can do
- Run a compliance check — steer/drive/trailer axle weights and CoG in, a legal/illegal verdict out, with the slide-to-legal fix.
- Pack a load in 3D — arrange boxes in a trailer, derive total weight and centre of gravity automatically, then check it.
- Import a manifest — read boxes from an Excel/CSV/Word/PDF load sheet instead of typing them.
- Issue certificates — every check can become a branded, QR-verifiable PDF you email to a driver, broker or shipper.
- Cover US & Canada — federal + verified states, and the Canadian interprovincial MOU with province rules, in imperial or metric.
- Integrate — one API endpoint, live + test keys, request logs and signed webhooks.

A word on how to read verdicts
LoadLegit gives compliance guidance, not legal advice, and results depend on the accuracy of what you enter. Always confirm against a certified scale and the governing authority before you haul. See Understanding the verdict.
