Using your headlights during fog, rain, or any low visibility condition is essential for safety. Headlights enhance your visibility to other drivers, allowing them to see you and recognize your position on the road, which is particularly crucial in adverse weather where visibility might be significantly reduced.

In low visibility conditions, it is best to use low beam headlights because high beams can reflect off fog, rain, or snow and create a glare that can impair your vision even further. By using headlights in these situations, you not only help ensure your safety but also contribute to the overall safety of the road for others.

The other options do not cover the full scope of when headlights should be used. For instance, only using headlights at night fails to account for critical daytime conditions like fog or heavy rain. Likewise, limiting their use to urban areas overlooks rural or highways where visibility can also be compromised. Lastly, relying on other cars having their headlights on may lead to unsafe situations where you are not visible at all times, particularly in varying weather and lighting conditions.
