Why these pages exist

Per-state oversize / overweight rules drift constantly — escort thresholds get tightened, holiday windows get expanded, admin code sections get renumbered. Dispatchers and pilot car operators end up bookmarking the state DOT permit page for every state they route through. These pages collect that information in one place, with the underlying admin code citation, and we keep them aligned with the rule library that powers OverSizeTMS.

If you spot an outdated threshold, email [email protected] and we'll verify and update — usually within 48 hours.
