The vehicle guards, also called pilot vehicles in most areas, are cars used to escort trucks with large loads, large vehicle convoys, guide motorists through construction sites, and assist aircraft in sliding from runway to asphalt at many airports. In many instances, pilot vehicles are provided by companies specializing in convoy escorts, although escorting is sometimes done by police vehicles (especially for parade and funeral or shipping processions requiring high levels of security during transit). Some escorts have special authority to control traffic through state approval.

The pilot vehicle/bodyguard is a public safety vehicle; they are also considered a warning tool to alert the public of potential hazards. They are usually equipped with a C.B. radio, or other two-way radios to communicate with each other. On a two-lane road, the load with one companion takes the position in front of the escorted load, on four or more escort roads which then transitions behind the escorted truck. Depending on the size of the load, the load may require more escort, usually one in front and one behind.
For trucks with excessive speed or too high, one of the companion vehicles will drive 2500 'to 1 mile in front of the truck to ensure the road ahead can accommodate the oversized truck's dimensions. The main vehicle is usually equipped with a long pole (tall pole) that extends upward from the front bumper; the length is adjusted six to eight inches above the height of the truck load or the highest part of the load in the convoy. If a pole crashes into a jutting object such as a bridge, the above sign, or power line, truck or convoy can be warned and stopped or diverted long before an accident occurs.
In Australia all oversized equipment is imported in the form of a piece on the cargo ship; the components are then loaded onto trucks strong enough to transport very heavy machinery. In New South Wales, large trucks are only allowed to operate between 11 pm and 5 am. If the truck is still in transit at 5 am, then it should withdraw law to a safe area and wait until 11 pm to continue its journey.
Along the predetermined route, which is already safe from the narrow streets and low objects through many years of transport of large oversized engines, the front companion should have a yellow safety light that can be seen from 360 Â ° and from at least 500 feet. Signs showing "Oversized Burden" must be on the front and rear of the bodyguard, or a sign that displays "Oversized Burden" on both sides can be mounted on top of the vehicle, the mark should be at least 5 feet wide and 12 inches high, with eight inches with 2 inch brush strokes. The front escort is to ensure that the vehicles coming are warned about the enormous load approaching. Since it is illegal for the front/escort pilots to cross into the oncoming lane, it can be difficult to get traffic to stop for something like a narrow bridge, so the front companion usually goes far enough in advance to alert the driver Truck over the CB radio about then cross that comes so the driver can stop before the bridge until the front driver relays back to the safe driver to cross without fear of oncoming traffic. The pilot/rearguard can perform tasks such as living in one or more lanes other than the truck and cargo lanes, to block traffic while trucks and trailers take turns. The rear companion can also make a sudden change of lane, usually because the truck needs to change lanes due to the end of lanes or obstacles on the road ahead, or one or more vehicles parked on the shoulder of the road.
