What is the primary role of pilot cars when transporting oversized loads?

The primary role of pilot cars when transporting oversized loads is to alert other drivers and ensure safety. Pilot cars, also known as escort vehicles, are used to guide oversized loads on the road. They function as moving warning signs that signal to other motorists about the presence of a large or wide load. This is crucial for maintaining safety on the road, as oversized vehicles can take up more space than typical vehicles, potentially causing hazards in traffic.

The pilot car helps manage traffic flow and can also coordinate with the truck driver to navigate tight spaces or difficult turns. Furthermore, it can communicate with the driver about any obstacles and help provide clearance when moving through narrower areas. This ensures that both the oversized load and other vehicles remain safe during transport.

Other roles, such as entertainment or carrying additional cargo, do not reflect the serious safety considerations that pilot cars are commissioned to fulfill. Likewise, while navigation assistance may be a peripheral function, the primary purpose is ensuring safety and managing the presence of oversized vehicles on the roads.
