Final answer:
When parking uphill against a curb, turn your wheels away from the curb so that the car will be stopped by the curb if the brakes fail.
Step-by-step explanation:
When you are parking uphill against a curb, the direction that your wheels should be turned depends on the way gravity will act on the vehicle if the brakes fail. If you are parking on a hill with a curb, you should turn your wheels away from the curb. This way, if the brakes fail, the car will roll and the back of the front wheel will hit the curb, preventing the car from rolling into traffic. Always remember to engage your parking brake as an additional safety measure.
This is because turning your wheels towards the street will help prevent your vehicle from rolling into traffic if the brakes fail. The curb will also act as a barrier, providing additional protection.
Remember, if you are parking downhill against a curb, you should turn your wheels to the right, or towards the curb.
