Final answer:
When parking downhill next to a curb, you should turn your front wheels towards the curb. This helps prevent the vehicle from rolling into traffic in the event that it begins to move. Turning the wheels to the right without a curb ensures it rolls away from the road.
Step-by-step explanation:
You need to turn your front wheels towards the curb while parking your vehicle downhill next to a curb. This technique ensures that if your vehicle starts to roll, the curb will help to stop the vehicle from rolling into the street, which could lead to accidents. It's also typically a legal requirement and a smart safety precaution.
Remember to turn the steering wheel to the right so that your wheels are pointing towards the curb when you are downhill with a curb. Without a curb, you should turn your wheels to the right so that if the vehicle moves, it will roll off the roadway rather than into traffic.
