What should you do every time you park a vehicle?

When parking a vehicle, engaging the parking brake is crucial because it helps to secure the vehicle in place, preventing it from rolling away. This is especially important on inclines or when the vehicle is on uneven ground. Utilizing the parking brake ensures that the vehicle remains stationary, thereby enhancing safety for both the driver and others nearby.

While turning off the ignition is important for shutting down the vehicle, and locking the doors enhances security, the primary safety function in this context is the act of activating the parking brake. Checking mirrors is advisable for ensuring clear surroundings while maneuvering but is not directly related to the act of parking itself.
