What safety feature should you always set when parking to prevent rolling away?

The parking brake is the crucial safety feature you should always set when parking your vehicle to prevent it from rolling away. This brake is specifically designed to hold the vehicle stationary, especially on inclines or uneven surfaces, by engaging the rear brakes independently of the regular brake system. The use of the parking brake ensures that even if the vehicle is not in gear, it remains securely stationary.

While the emergency brake and handbrake essentially refer to the same feature as the parking brake, it's important to note that different terminology may lead to confusion in different contexts. The foot brake is what you use while driving to slow down or stop the vehicle, but it does not provide the stationary hold that is necessary once the vehicle is parked. Therefore, always ensuring that the parking brake is engaged is a vital practice for safe parking.
