When parking facing downhill next to a curb, which way should you turn your front wheels?

When parking facing downhill next to a curb, turn your front wheels toward the curb (to the right when the curb is on your right). That way, if the vehicle begins to roll, the front wheel catches against the curb and stops it. When facing uphill with a curb, turn the wheels away from the curb so the vehicle rolls back into it. When there is no curb (uphill or downhill), turn the wheels toward the edge of the road so a rolling vehicle moves away from traffic. Always also set the parking brake and leave the vehicle in park (or in gear for a manual). Proper wheel position is a tested parking-safety rule.
