Final answer:
To safely park a car facing uphill, the steering wheel should be turned away from the curb which ensures the car rolls into the curb rather than into oncoming traffic if it begins to move.
Step-by-step explanation:
When a car is facing uphill, the correct way to direct the steering wheel is away from the curb. This ensures that if the car were to start rolling, it would roll into the curb, and not into the traffic lane. By turning the steering wheel towards the road, the front wheels are directed so that the car would back into the curb instead of potentially rolling into oncoming traffic. This is a standard precautionary measure to prevent accidents in case the parking brake fails.
