When parallel parking downhill, which direction should you turn your wheels?

When parallel parking downhill, the correct action is to turn your wheels toward the curb. This positioning ensures that if your vehicle were to roll, it would roll into the curb rather than into the street. By pointing the wheels right toward the curb, gravity is countered effectively. The curb serves as a barrier, reducing the risk of your vehicle rolling away and causing potential accidents.

Turning your wheels away from the curb, leaving them straight, or turning in the direction of the street does not provide the necessary safety measure in the event of a vehicle movement, making those options less suitable for safe parking on a downhill slope.
