What is an emergency brake primarily used for?

The emergency brake, also known as the parking brake or handbrake, is primarily designed to secure a vehicle when it is parked. Its main function is to hold the car stationary, especially on inclines or declines, preventing it from rolling away. This is particularly important when the vehicle is left unattended.

While the emergency brake can sometimes assist in slowing down a vehicle in specific situations, that is not its primary intent. Its use during emergencies to stop a car quickly or aid in reverse parking are not standard practices for the emergency brake. Using it for those purposes can lead to loss of control or unexpected vehicle handling. Thus, understanding its role in securing the vehicle when it is parked is crucial for safe driving practices.
