What must you do to the vehicle when using a receiver hitch?

• A. Engage the E brake
• B. Chock the wheels
• C. Both chock the wheels and engage the E brake
• D. Put the vehicle in park

Answer: (C)

Securing the vehicle with wheel chocks and the parking brake provides two independent protections against movement when you’re working with a receiver hitch. Wheel chocks physically block the tires, so a slope or any tug from the hitch can’t cause the vehicle to roll. The parking brake adds braking force to lock the wheels in place, which is especially important during hitching or hitch removal when there may be slight shifts or loads transferred through the hitch. Relying on being in park alone isn’t as reliable—if the parking mechanism slips, or if you’re on even a gentle incline, the vehicle could move. Using both chocks and the parking brake minimizes movement risk and keeps the setup safe.
