Oversize routing for oversize loads

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 in any state.

Any state

Any state, plus Texas import

In any state, build the route yourself in PermitPath by dropping the waypoints from your permit, then navigate that path on iOS or Android. That manual build is the main way most drivers use the app.

For Texas oversize permits, the Texas Department of Motor Vehicles issues oversize and overweight permits through TxPROS. PermitPath does not issue those permits. After you have one, you can also import the official TxPROS route from the PDF or QR code. Texas import is an extra feature—not a requirement to use PermitPath.

Definitions

What is oversize routing?

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.

The permit

What is permit routing?

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.

Why it matters

Stay on the permit path

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 tickets and fines for being off your permit routing, delays while you work with the permit office to correct the route, and safety risks around low bridges, tight turns, and restricted roads.

A dedicated oversize routing app like PermitPath helps you stay locked onto the permit route from start to finish.

In the app

How PermitPath helps with oversize routing

Pin the route

Match the permit

Pin your start, end, and all permit waypoints so the line in the app matches the route on the permit.

No artificial cap

Unlimited waypoints

Add every turn or major change the permit needs. Save and edit the route when the permit changes.

Office and truck

Share iOS and Android

Share routes between iOS and Android so everyone on the job is on the same path.

Texas option

Official TxPROS import

When you have a Texas TxPROS permit, import the official route from a PDF or QR instead of rebuilding the paper directions.

The goal is simple: your oversize routing in the app should match your permit routing on paper.

Before you roll

Best practices for oversize routing

Always read the permit first and highlight the official route. Enter the same start, end, and major waypoints into PermitPath. Double-check low bridges, weight limits, and curfews before you roll. Keep your permit and the app in sync—edit the route if the permit changes.
