Final answer:
When parking facing uphill with a curb, turn your front wheels towards the curb to prevent the vehicle from rolling downhill.
Step-by-step explanation:
When parking facing uphill with a curb, you should turn your front wheels towards the curb. This means you should steer your wheels to the right so that they are touching or very close to the curb. This is done to prevent the vehicle from rolling downhill in case the parking brake fails.
By turning your front wheels towards the curb, you create a physical barrier that can help prevent the vehicle from moving forward and rolling down the hill. This is especially important when parking on a steep hill or incline.
Remember that it is important to set the parking brake as well, even when parking with your wheels turned towards the curb.
