In which scenario should your wheels not be pointed straight ahead?

When parked on a hill or sloping driveway, your wheels should not be pointed straight ahead. Instead, it's important to turn your wheels towards the curb or edge of the road if you are facing downhill, or away from the curb if you are facing uphill. This ensures that if your vehicle starts to roll, it will be directed toward the curb or roadside, reducing the risk of it rolling into traffic or causing an accident. This practice enhances safety in situations where gravity could cause the vehicle to move unexpectedly.

In contrast, when parked on a level street, your wheels can be pointed straight ahead without posing a risk, as there is little chance of the vehicle rolling away. Similarly, when stopped at a traffic light or waiting for pedestrians, there is no need to adjust the direction of your wheels in anticipation of movement or potential hazards, as the vehicle is in a controlled stop.
