What should you do with your wheels when parking on a slope?

When parking on a slope, it is important to position your wheels inward towards the curb. This method is designed to prevent the vehicle from rolling down the hill in case it starts to move. If the vehicle were to roll, with the wheels turned towards the curb, the front tires would come into contact with the curb and help to stop the vehicle from rolling further. This is a critical safety measure that can prevent accidents and property damage.

When parking uphill specifically, turning the wheels away from the curb would allow the vehicle to roll away from the curb if it were to move, which could cause it to roll into traffic. Keeping the wheels straight does not offer any assistance in halting the vehicle's motion if it begins to roll, therefore it is less safe than turning them towards the curb.

Overall, turning the wheels inward is the recommended action to ensure the safety of both the parked vehicle as well as other road users.
