Back-of-Cab Access, General Description
When trailer air and electrical connections cannot be reached conveniently from the ground, Federal Motor Carrier Safety Regulations require commercial carriers to provide back-of-cab access.
A grab handle is typically located on the back wall of the sleeper or cab. Steps are mounted on the frame rail, and a deck plate is mounted across the top of the frame rails. See Fig..
Caution: Follow these rules for back-of-cab access. Failing to follow these rules could lead to a fall, and possible personal injury.
Never step on any exterior part unless it has a slip-resistant surface meant for safe stepping. If the surface is movable, such as a battery box cover with a slip-resistant surface, be certain it is firmly secured.
Be careful not to trip on items such as chains or air lines in the back-of-cab area.
Always follow safety procedures for back-of-cab access, maintaining three-point contact both hands and one foot, or both feet and one hand whenever moving around, and always face in toward the deck plate when climbing up or down.
Wet or dirty shoes, steps, or grab rails greatly increase the chance of slipping or falling. If your shoes or the contact areas are wet or dirty, clean and dry them as much as possible before accessing the back of cab area, and be especially careful when climbing or standing on the vehicle.
Never jump onto, or off of, a vehicle; doing so creates a very high likelihood of a fall and personal injury.
Important: Climb onto, and down from, back-of-cab access facing in toward the vehicle, as you would on a ladder. Do not climb up or down facing out away from the vehicle.
