What is Chock?
Chock, also known as a wheel chock, is a wedge-shaped block placed in front of a vehicle’s wheels to prevent accidental movement. These devices are essential for safely securing parked vehicles, especially on inclines or uneven surfaces.
Types of Chocks
- Wooden Chocks
- Rubber Chocks
- Metal Chocks
Importance of Chocks
Chocks play a crucial role in enhancing vehicle safety. They prevent vehicles from rolling away and causing accidents, injuries, or damage to property. In the aviation industry, chocks are also used to securely park aircraft on the tarmac.
Examples of Chock Usage
For example, a truck driver delivering goods to a mountainous region uses chocks to secure the vehicle while loading or unloading cargo. In another scenario, an aircraft maintenance crew uses chocks to immobilize a plane during routine checks.
Case Studies
In a study conducted by the National Transportation Safety Board (NTSB), it was found that the majority of accidents involving parked vehicles could have been prevented by using chocks. This highlights the importance of chocks in vehicle safety.
Statistics on Chock Safety
According to the Federal Motor Carrier Safety Administration (FMCSA), over 12% of all accidents involving parked commercial vehicles are caused by inadequate parking brake systems or the absence of chocks. This underscores the need for proper chocking procedures.
