What should you do when parked facing downhill?

When parked facing downhill, the appropriate action is to turn your wheels toward the curb. This is important for safety because if the vehicle were to roll, the curb would act as a barrier to prevent it from rolling into traffic or causing an accident. By turning your wheels toward the curb, you create a situation where the car will roll back into the curb rather than into the street.

In contrast, leaving your vehicle in neutral, turning your wheels away from the curb, or leaving your wheels straight does not provide the necessary safety measure to prevent unintended movement of the vehicle. Each of these actions could result in the vehicle rolling into the road, posing a risk to both the vehicle and surrounding traffic. Hence, turning the wheels toward the curb is the safe and recommended practice.
