What is the proper way to park on a downhill without a curb?

When parking on a downhill without a curb, the proper way to position your wheels is to turn them towards the edge of the road. This technique helps to ensure that if your vehicle were to roll, it would roll off the roadway rather than into oncoming traffic or nearby obstacles. The intention is to create a barrier or safety feature by directing the path of the vehicle downhill, thereby reducing the risk of accidents.

In contrast, keeping your wheels straight or turning them away from the edge of the road does not effectively mitigate the risk of a rolling vehicle. If your wheels are straight, there's nothing to prevent the vehicle from rolling straight down the hill into danger. Similarly, turning your wheels away from the edge does not provide the necessary protection against unintended movement down the slope. Parking with just the emergency brake is also inadequate, as it may not hold the vehicle securely, especially on a steeper incline. Thus, turning your wheels towards the edge of the road is the safest and most effective method in this situation.
