If there is no curb, then turn your front wheels toward the edge of the road regardless of whether you’re parking up or down. This way, your car will roll into the dirt or grass beside the road, and not into the path of oncoming traffic. Avoid “dry steering” – turning your wheels while the vehicle is completely stopped. This puts pressure on the tires and the power steering system. [3] X Research source
Make sure that there are no other cars coming up or down the hill behind you. Check your mirrors and look over your shoulder.
If you are parking uphill, make sure to leave a full car’s length of space behind your vehicle. You will need this space to back into the curb. If you are parking on a downhill incline, be sure to leave a full car’s length of space in front of your car so that the wheels can roll forward into position.
