Pilot Car Equipment
Usually pilot cars, the truck, and the cargo have large yellow signs on them indicating that this is an oversized or wide load. Some of the cars have flashing lights, like post office vehicles, as well as bright yellow flags to alert all other drivers to drive more carefully. They also have CB radios to talk with the truck driver and other pilot car drivers. Some of them carry emergency equipment like first aid kits and other necessary items. Very tall loads require pilot cars to have poles on them that measure the height of bridges and other obstacles to ensure that everything will fit.
