Final answer:
The correct wheel to make contact with the curb when parking uphill with a curb is the back wheel. It is a safety measure to prevent the vehicle from rolling into traffic if the brakes fail.
Step-by-step explanation:
The correct wheel to make contact with the curb when parking uphill with a curb is the back wheel. It is a safety measure to prevent the vehicle from rolling into traffic if the brakes fail. When parking uphill where there is a curb, the correct wheel to make contact with the curb is the back wheel.
This technique is a safety precaution to prevent the car from rolling into traffic if the brakes were to fail. You should turn your wheels away from the curb so that if your vehicle starts to move, it will roll into the curb and stop, rather than into the road. However, if there is no curb, you should turn the steering wheel toward the side of the road. This ensures that if the vehicle rolls, it will roll away from traffic, thereby minimizing potential hazards.
