what way should you turn your wheels when parking uphill without a curb?

When parking uphill without a curb, turn your front wheels away from the curb or to the left if you are parking on a two-way street. This is because if your car starts to roll, it will roll back and hit the curb, using it as a block. If there is no curb, turning your wheels to the left will cause your car to roll off the highway, not into traffic.
