Final answer:
When parking on a hill with a curb facing downhill, the wheels of your vehicle should be facing towards the curb. This prevents the vehicle from rolling downhill.
Step-by-step explanation:
When parking on a downhill slope with a curb, it is advisable to position the wheels of your vehicle facing towards the curb. This practice, commonly referred to as parking with the wheels turned towards the curb, serves as a safety measure. By orienting the wheels in this manner, the curb acts as a physical deterrent, potentially preventing the vehicle from rolling further in the event of brake failure or external force application.
This strategic positioning of the wheels creates a protective barrier, enhancing the vehicle's stability on the downward incline. In essence, the curb serves as a supplementary safety feature, acting as a reliable obstruction to mitigate the risk of unintended movement.
Conversely, when parking uphill with a curb, the recommended practice is to turn the wheels away from the curb. This precautionary measure is designed to prevent the vehicle from rolling into oncoming traffic. By directing the wheels away from the curb in an uphill parking scenario, the vehicle's natural movement tendencies work in conjunction with the incline, reducing the likelihood of any unintended forward motion. This simple yet effective approach contributes to overall road safety and responsible parking practices.
