When parking downhill, how should the wheels be turned?

When parking downhill, the correct way to turn the wheels is toward the curb. This action is a safety measure designed to prevent the vehicle from rolling into the street if the brakes were to fail. By turning the wheels toward the curb, if the car does start to roll, the front tire will make contact with the curb and help stop the vehicle from moving further downhill. This technique is crucial for ensuring safety not only for the parked vehicle but also for other road users.

Selecting other options would not provide the same safety benefits. For instance, turning the wheels away from the curb or keeping them straight would not help in preventing the vehicle from rolling into traffic, increasing the risk of a collision or accident.
