Final answer:
When parking on a hill, turn your front wheels into the curb when facing downhill. If facing uphill with a curb, turn them away from the curb, and if there's no curb, turn them to the right.
Step-by-step explanation:
When parking on a hill, the correct procedure for turning your wheels depends on the direction of the hill. If you are parked downhill, you should turn your front wheels into the curb or towards the side of the road if there is no curb. This action prevents the car from rolling into traffic if the brakes fail. On the other hand, if you are parked uphill with a curb, you should turn your wheels away from the curb so the back of the front wheel can catch on the curb in the event of brake failure. If you are parked uphill without a curb, turn your wheels to the right so the car will roll off the road rather than into traffic.
