When parking on a hill with the vehicle facing downhill, what should you do with your front wheels?

When parking on a hill with your vehicle facing downhill, the correct action is to turn your front wheels towards the curb. This is an important safety measure designed to prevent the vehicle from rolling into traffic if the parking brake fails. By turning the wheels towards the curb, if the vehicle were to roll, the curb would act as a barrier, preventing it from moving further down the hill.

The other options do not provide the same level of safety. For instance, turning the wheels away from the curb or leaving them straight would allow the vehicle to roll into the street, potentially causing accidents. Hence, always remember to turn your front wheels towards the curb when parking downhill to ensure maximum safety.
