For safety when parking downhill, turn your wheels toward the curb if one is present, or toward the side of the road if there is no curb.
When parking downhill, whether there is a curb or not, it is important to turn the wheels in a specific direction for safety. If there is a curb, you should turn your wheels toward the curb. If there is no curb, turn the wheels toward the side of the road. This ensures that if your vehicle starts to move, it will roll into the curb or away from traffic, minimizing the potential for an accident.
