Final answer:
When parking facing up a steep hill next to a curb, your front wheels should be turned towards the curb to prevent the vehicle from rolling down the hill.
Step-by-step explanation:
When parking facing up a steep hill next to a curb, your front wheels should be turned towards the curb. This is known as uphill parking with a curb. By turning the front wheels towards the curb, it helps prevent the vehicle from rolling down the hill if the brakes fail or if there is excessive downhill pressure. The curb acts as a barrier to keep the vehicle in place.
To further illustrate this, imagine your vehicle is parked facing uphill on the right side of the road. If the front wheels are turned away from the curb, towards the road, and the vehicle starts rolling downhill, it could potentially roll on to the road and pose a danger to other drivers.
Therefore, it is safest to always turn the front wheels towards the curb when parking facing up a steep hill next to a curb.
