These are aftermarket or factory-installed accessories designed to aid in entering and exiting the vehicle, particularly useful for trucks with higher ground clearance. They typically mount along the rocker panels beneath the doors and provide a stable platform for drivers and passengers.
The inclusion of these features offers numerous advantages, including enhanced accessibility, especially for individuals with mobility challenges or smaller stature. They can also protect the vehicle’s lower body from road debris, such as rocks and mud, mitigating potential damage and maintaining the aesthetic appeal. Historically, such additions evolved from simple running boards to more integrated and stylistically diverse components, reflecting changing vehicle design and user needs.
