If you want to park downhill, what should you do?
Put two of the wheels on the kerb to ensure safety
Turn your steering wheel in the direction of the kerb, and make sure you turn on the handbrake
Put one wheel on the kerb to ensure safety
Explanation: When you stop your car headed downhill, turn your front wheels toward the kerb. When headed uphill (or downhill) with no kerb, always turn your front wheels to the right so that if your vehicle moves, it will roll off the highway, not into traffic.
