When is it appropriate to use your parking brake?

Using the parking brake is essential when parking a vehicle to ensure it remains securely in place. Engaging the parking brake creates friction that prevents the car from rolling, particularly on slopes or uneven surfaces. This practice is especially important in preventing accidental movement that could lead to accidents or injuries.

While there are other appropriate situations to use the parking brake, such as during emergency scenarios or while on a downhill incline, these instances are more situational and not its primary purpose. The parking brake is designed specifically to secure a vehicle when parked, making option B the most appropriate choice. Generally, it is good practice to always engage the parking brake, even on flat surfaces, as a precautionary measure against any unintended vehicle movement.
