Every time someone steps into a van or truck, chances are they are using a running board. Every time a person drives a truck, chances are he is using a running board. The running board is among the most common and most useful features of van and truck design, and it is also one of the most subtle--something people use every day without even knowing it.
A running board is located along the bottom of the vehicle on either side, and it is commonly located at the foot of a door.
The running board serves two main functions. The first is to serve as a step to make it easier for passengers to step up into the vehicle. Vans and trucks are high off the ground, and without a step between the ground and the vehicle, entry can be difficult, especially for passengers who have trouble walking. The second function is to protect the vehicle from road debris. When a van or truck is moving, the wheels kick up rocks, dirt and other items. A running board blocks those items from scratching and denting the side of the vehicle.
Aside from making the vehicle more ergonomic and protecting it from minor damage, a running board can also help keep the interior of the van or truck clean by serving as a doormat upon which passengers can wipe their feet before entering.
A running board can be made of many materials. It can be diamond-plate steel, rubber, plastic or fiberglass, or even a tubelike structure that runs around the perimeter of the vehicle (this is a popular feature on Jeeps.)
Because a running board serves as a small step ladder, it is important that it stays clean and dry. Some are manufactured with a gripping surface to improve traction. These surfaces wear out over time, but van and truck owners can preserve the traction of their running board easily and inexpensively by applying deck tape, an accessory commonly used by skateboarders.
