Final answer:
When parking uphill with a curb, turn the wheels of the vehicle to the left.
Step-by-step explanation:
When parking uphill with a curb, you should turn the wheels of the vehicle to the left.
This is because when you park uphill, the curb acts as a block and prevents the vehicle from rolling downhill. By turning the wheels to the left, the vehicle will roll towards the curb if the brakes fail, reducing the chance of it rolling into the road.
Turning the wheels to the left is the proper technique for parking uphill with a curb and ensures the safety of the vehicle and others on the road.
