When parking on a hill that does not have a curb, which direction should you turn your wheels?

When parking on a hill that does not have a curb, you should turn your wheels towards the grass or ditch. This is crucial because if the vehicle starts to roll, the wheels will guide it away from the road and into a safer area, preventing it from moving into traffic or a dangerous situation. Turning the wheels in this direction employs gravity to help keep the vehicle stationary, effectively using the natural landscape features to create a barrier.

In contrast, turning your wheels away from the road would put your vehicle into the path of danger if it were to roll. Parking parallel to the road might not provide any form of safety, as the vehicle could still roll into traffic. Saying that any direction is acceptable overlooks the necessity of taking safety precautions to mitigate the risks associated with potential rolling.
