Heavy haul
Pilot Car & Escort Requirements
Many oversize permits come with escort conditions. Knowing what may be required before you book the move helps avoid last-minute delays and surprises at the permit stage.
What commonly triggers escort requirements
The exact triggers, number of escorts, and positions (front, rear, or both) are set by each state and are usually spelled out in the permit itself.
- Width, height, or length beyond levels set by the state for the type of road.
- Long overhangs or unusual load shapes.
- Two-lane, undivided, urban, or mountain roads where visibility is limited.
- Superload moves, which may require multiple escorts or law-enforcement escorts.
Route surveys and height poles
- Tall loads may require a front escort with a height pole to check clearances.
- Very large moves may require a route survey before the permit is approved.
- Utility crews or traffic control may be needed where lines or signals must be raised or moved.
State-by-state differences
- Some states require certified or licensed escort drivers; certification rules vary.
- Equipment rules — signs, lights, flags, radios — differ by state.
- An escort that's compliant in one state may not meet the next state's rules.
- Requirements change; confirm with the issuing agency and the permit conditions.
Common delays and problems
- Escorts booked late, or not certified for every state on the route.
- Permit conditions that change the route after escorts are scheduled.
- Travel-time, weather, or holiday restrictions that shift the move date.
