Oversize routing and permit routing is about following the exact path your state permits require. For heavy-haul and oversize loads, the route on the permit is the law—deviating can mean fines, delays, or worse. This guide explains what oversize routing is and how PermitPath helps you stay on your permit-approved route.
Oversize routing is the process of planning a path for a load that exceeds legal size or weight limits. Instead of just “shortest” or “fastest,” oversize routing must respect bridge limits, lane widths, curfews, construction, and state-by-state rules. The route is usually specified on your oversize or overweight permit, and you are expected to follow that permit routing exactly.
Permit routing is the route printed on the state permit itself. States may specify highways, exits, turn-by-turn directions, mile markers, or written instructions like “follow I‑80 WB to Exit 123, then US‑30 WB.” When you are hauling an oversize or overweight load, permit routing becomes your official navigation plan. Your job is to match your real‑world driving to that permit routing.
Missing a turn on an oversize permit route can push you onto roads that are too low, too narrow, or not legal for your weight or dimensions. That can lead to:
A dedicated oversize routing app like PermitPath helps you stay locked onto the permit route from start to finish.
PermitPath is built specifically for oversize routing and permit routing. Instead of trying to force a car GPS to match your paper permit, you can:
The goal is simple: your oversize routing in the app should match your permit routing on paper.
