Final answer:
When parallel parking downhill with a curb, you should turn your wheels towards the right so that the car rolls into the curb if it starts to roll.
Step-by-step explanation:
When parallel parking downhill with a curb, you should turn your wheels so that they face towards the curb. This is known as turning your wheels to the right. By doing this, if your car starts to roll, it will roll into the curb and prevent it from rolling into traffic. Turning your wheels to the left is the correct way to park when parallel parking uphill with a curb.
