Escort vehicle

An escort vehicle, also called a pilot vehicle in most areas, is an automobile used to escort trucks with large loads, convoys of large vehicles, guide motorists through construction sites, and assist aircraft in taxiing from the runway to the tarmac at many airports. In most instances, pilot vehicles are provided by companies that specialize in convoy escort, although escort duties are occasionally performed by police vehicles (especially for parades and funeral processions or shipments that require a high level of security during transit).
