Wheel Chocks
Frequently Asked Questions
Find answers to commonly asked questions below.
-
What is the purpose of a wheel chock?
The purpose of a wheel chock is to prevent a vehicle or equipment from unintentionally moving while parked or during loading and unloading. Wheel chocks are placed against the wheels to create a physical barrier that resists rolling, especially on inclines or uneven surfaces. They are commonly used for trucks, trailers, aircraft, and heavy machinery to enhance safety and stability.
-
Do you need 1 or 2 wheel chocks?
You typically need two wheel chocks for maximum safetyāone for each side of the wheel or for both wheels on an axle. Using only one chock may reduce effectiveness, especially on slopes or when the vehicle is heavy. Placing chocks on both sides ensures the vehicle remains stationary even if external forces, such as wind or vibrations, occur.
-
What is the OSHA rule for wheel chocks?
OSHA rules for wheel chocks require that trucks and trailers be secured with chocks during loading and unloading operations to prevent accidental movement. Specifically, OSHA mandates that employers provide and enforce the use of wheel chocks for vehicles parked at docks or on inclines. This regulation helps protect workers from injuries caused by unexpected vehicle movement.

What is the purpose of chock?
The purpose of a chock is to act as a wedge or block that stabilizes and secures wheels, preventing rolling or shifting. Chocks are essential safety devices in transportation, construction, and aviation industries. They are made from durable materials like rubber, metal, or polyurethane to withstand heavy loads and harsh conditions. By creating friction and a physical barrier, chocks reduce the risk of accidents and equipment damage.
