A car footstep, also known as a running board or side step, is an external accessory typically attached to the side of a vehicle, near the bottom of the doors. It serves as a platform for passengers to step onto when entering or exiting the vehicle, especially for taller vehicles like SUVs or trucks. Footsteps can be purely functional or decorative, and they come in various materials and designs to complement the aesthetics of the vehicle. They can enhance accessibility and add a touch of style to the vehicle's exterior.
