Final answer:
When parking downhill with a curb, your tires must be turned towards the curb as a safety measure to prevent the vehicle from rolling into traffic if brakes fail.
Step-by-step explanation:
When parking downhill with a curb, the correct way to position your tires is towards the curb. This technique ensures that if your vehicle's brakes were to fail, the car would roll into the curb, minimizing the chance of it rolling into traffic and potentially causing an accident. Always remember to apply your parking brake after turning the wheels towards the curb.
When you are parking uphill with a curb, the method is slightly different; you should turn your front wheels away from the curb so that if the vehicle starts to roll, it will also roll into the curb for safety reasons. Without a curb, whether parking uphill or downhill, the wheels should be turned toward the side of the road. Utilizing proper wheel positioning is an important aspect of safe and responsible driving.
Practicing these safe parking habits should become second nature to ensure the safety of both your vehicle and other road users. In driving tests and general practice, correct positioning of wheels while parking is often assessed and is an essential skill for all drivers to master.
