What is the correct procedure when parking on a hill?

When parking on a hill, the correct procedure is to turn the wheels towards the curb or roadside. This practice is essential for preventing the vehicle from rolling into traffic if it were to move accidentally. By directing the wheels toward the curb, gravity will pull the car into the curb if it starts to roll, reducing the risk of it sliding down the hill and into the path of other vehicles or obstacles.

In contrast, keeping the wheels straight would not provide any protection against rolling away, as the vehicle could simply move forward or backward unchecked. Turning the wheels away from the curb is also unsafe because if the vehicle were to roll, it could roll into traffic instead of staying put. Leaving the vehicle in neutral poses a significant risk as it allows the car to move freely downhill without any restraint, which can lead to dangerous situations both for the vehicle and for other road users. Thus, turning the wheels towards the curb or roadside is the safest and most responsible approach when parking on a hill.
