When parking downhill with a curb, you should turn your wheels:

Answer: A — Towards the curb.

When parking downhill with a curb, turning your wheels towards the curb is the safest option because it prevents your car from rolling into oncoming traffic in case the brakes fail. Turning your wheels away from the curb or parallel to the curb could potentially cause your car to roll down the hill if the brakes fail. Choosing option D, "It doesn't matter," is incorrect because it is important to follow the proper procedure for parking on a hill to ensure the safety of yourself and others.
