A running board is a platform attached to a vehicle’s doors that helps passengers easily board and leave the car. Running boards are located at the bottom of vehicles (on either or both sides) typically at the foot of a truck’s door. They serve two main functions. Without an extra step into some of the taller models, getting into a truck will feel like climbing a mountain. Protecting vehicles from various forms of road debris is a second function of running boards. When vehicles move their wheels kick up all kinds of debris (…from rocks and dirt to other more destructive things like nails). Having a running board in place can block some of this debris from being thrown high enough to scratch and/or damage doors and side panels.
