Final answer:
When parking a vehicle facing uphill with a curb on the right side, turn the front wheels away from the curb. This prevents the car from hitting the curb if it starts rolling.
Step-by-step explanation:
When parking a vehicle facing uphill and there is a curb on the right side of the car, you should turn the front wheels away from the curb. This means turning the steering wheel to the left. By doing so, if the car starts rolling, it will roll away from the curb and prevent it from hitting the curb. This technique is called 'curb-side parking'.
For example, imagine you are parking on a hill where the curb is on the right side of your car. If you turn the front wheels to the right, towards the curb, and the car starts rolling backwards, the front wheels will hit the curb and prevent the car from rolling further downhill. On the other hand, if you turn the front wheels to the left, away from the curb, if the car starts rolling backwards it will roll away from the curb and prevent it from hitting the curb.
