The appropriate time to keep your parking brakes engaged is when parking on a steep hill. Engaging the parking brake helps to prevent the vehicle from rolling, which is particularly important on inclines where gravity could cause the vehicle to move.

On flat surfaces, the parking brake may not be necessary, but it’s a good practice to use it every time you park. In the case of parking on a steep hill, the risk of the vehicle rolling away is significantly increased, thereby making the use of the parking brake essential for safety.

While parking on a two-way road with a limit exceeding 30mph may require precautions, it is not an explicit scenario necessitating the use of the parking brake. Similarly, parking in a garage or on single-lane roads may not always present the same risk of rolling as parking on a steep incline, and the situation regarding the need for the parking brake can differ based on terrain and conditions of the specific parking environment.
