What is the purpose of a wheel chock?

The purpose of a wheel chock is to prevent a vehicle from rolling. This is particularly important when vehicles are parked on an incline or uneven surfaces, as there is a risk of the vehicle shifting or moving unexpectedly. By placing wheel chocks securely against the tires, the vehicle is stabilized and the likelihood of it rolling away is significantly reduced. This is critical not only for the safety of personnel working around the vehicle but also for the protection of equipment and property nearby. In firefighting operations, where vehicles are often positioned on varying terrains, utilizing wheel chocks ensures that the vehicle remains safely stationary during emergency response activities.
