Chocks are used in buses to prevent them from rolling or moving when parked. They are placed in front of and behind the wheels to ensure that the bus stays in place and does not accidentally move, especially when parked on an incline. This is an important safety measure to prevent accidents and ensure the safety of passengers and other vehicles in the vicinity. **

Wheel chocks are properly placed on the car by positioning them on the front and back of the rear wheels. The chocks should be placed snugly against the tires to prevent any movement of the vehicle. It is important to ensure that the chocks are placed on a flat surface and are securely in place before performing any work on the vehicle. Additionally, it is recommended to use at least two wheel chocks for added stability. **

The placement of chocks depends on the specific situation and the type of vehicle being secured. In general, chocks are placed in front of the wheel when the vehicle is facing downhill, and behind the wheel when the vehicle is facing uphill. However, it is important to follow the specific guidelines provided by the manufacturer or the organization responsible for the safety of the vehicle. It is also crucial to ensure that the chocks are properly positioned and secured to prevent any movement of the vehicle. **

True serenity involves a sense of inner peace and contentment, while indifference may lead to a disconnect from emotions and relationships. **
