These accessories, designed specifically for the designated vehicle model and year, are narrow, elongated steps installed along the sides, beneath the doors. Their primary function is to provide an intermediate step between the ground and the vehicle’s cabin, easing entry and exit. Examples include both fixed and retractable styles, available in materials such as aluminum, steel, and composite polymers.
The inclusion of these components offers several advantages. They enhance accessibility, particularly for individuals with limited mobility or those of shorter stature. These additions can also protect the vehicle’s rocker panels from road debris, reducing the risk of scratches and dents. Historically, similar devices have been employed on vehicles with high ground clearance to improve passenger convenience and safeguard the vehicle’s body.
