Answer :
Final answer:
To ensure a car remains stationary while unattended, a driver should engage the parking brake. This mechanical action locks the wheels, preventing the vehicle from rolling away unintentionally. Therefore the correct answer is: a)
Explanation:
To keep a car from moving while unattended, a driver should engage the parking brake. This action ensures that the vehicle remains stationary even on an incline. Engaging the parking brake mechanically locks the wheels, preventing them from turning and thereby stopping the car from inadvertently rolling away. This is a critical safety measure when parking on any gradient and is equally important on flat surfaces, as it provides an additional layer of security besides the vehicle's transmission lock.
Shifting to neutral, turning off the headlights, or activating the hazard lights do not directly prevent a car from moving. While turning off headlights and activating hazard lights are important in specific scenarios for visibility and safety, they do not affect the car's physical ability to move. The parking brake, however, specifically addresses this need by mechanically restricting wheel movement.
