A pilot driver operates a car that escorts oversized trucks and other large vehicles. Your duties include driving an automobile in front of or behind the oversized vehicle. As you drive, your responsibilities include communicating with the truck driver to ensure that they are aware of any upcoming situations such as traffic jams, stop lights, or other obstacles. If you drive behind the truck, you ensure that the load remains secure during the trip. An escort vehicle sometimes has a siren or lights that warn other drivers of the presence of an oversized vehicle on the roadway.
