Final answer:
When parking uphill on a street with a curb on your right, your wheels should be facing to the left to prevent the vehicle from rolling downhill if the parking brake fails.
Step-by-step explanation:
When parking uphill on a street with a curb on your right, your wheels should be facing to the left.
This is important because it helps prevent the vehicle from rolling downhill if the parking brake fails. When your wheels are turned to the left, they will roll away from the curb, which helps create a buffer to keep the vehicle stationary.
For example, imagine you are parking uphill on a street with a curb on your right. If your wheels are turned to the right, the vehicle will roll downhill and potentially cause an accident. But if your wheels are turned to the left, the vehicle will roll away from the curb, minimizing the risk of it rolling downhill.
