What is the main function of a Wheel Chock?

  1. To increase the speed of towing.

  2. To prevent the vehicle from rolling.

  3. To enhance the aesthetics of the vehicle.

  4. To repair minor damages to tires.

The correct answer is: To prevent the vehicle from rolling.

The main function of a wheel chock is to prevent the vehicle from rolling. When a vehicle is parked, especially on an incline or uneven surface, a wheel chock acts as a physical barrier that blocks the wheels from moving. This is crucial in ensuring the safety of personnel working on or around the vehicle, as preventing unintended movement reduces the risk of accidents. Using wheel chocks is a standard safety practice in towing and vehicle maintenance, as they provide additional security when vehicles are stationary, particularly during service operations or when backing up to a tow. By effectively securing the vehicle in place, wheel chocks help maintain a safe working environment for all involved. This function is essential for compliance with safety regulations and best practices in the industry.
