Wheel chocks are used for safety and accident prevention. Chocking, also known as blocking, is done to prevent trucks and trailers from unintentionally moving, like rolling or overturning, while workers are loading, unloading, hitching, unhitching or servicing the vehicle.

When should you chock the wheels?

OSHA mandates that your vehicle must be chocked before being unloaded. (A detached trailer must be jacked up with the rear wheels chocked). Wheel chocks should be used on a level surface with the chocks placed flush with the tires of the wheel that you are blocking. Place the chocks against the center of the tires.
