Some oversize moves call for more than pilot cars. Permits and local rules decide if law enforcement joins the convoy. The goal is the same. Keep people safe, protect the load, and keep traffic moving.
A police escort is a marked law enforcement unit assigned to the move. Officers drive ahead or alongside to manage traffic for an oversize load. They coordinate with dispatch, block intersections when allowed, pace speeds, and help the convoy clear tight or high-risk areas.
Police escorts are required when permits specify them. Triggers can include extreme width or length, tight urban corridors, bridges and tunnels, peak-hour windows, stadium or event zones, and sensitive routes. Some states add a police escort on top of pilot cars. Others use police instead of pilots on certain roads or at certain times.
Pilot cars communicate hazards and help the driver set up safe moves. A police escort holds legal authority. Officers can direct traffic, control intersections, and enforce closures.
