Under what condition should you use your headlights?

Using your headlights during fog or heavy rain is essential for enhancing visibility and ensuring safety on the road. In these conditions, the ability to see and be seen is significantly compromised due to reduced visibility. Fog can reflect light, creating glare, which can be mitigated by using low-beam headlights. Similarly, in heavy rain, headlights help illuminate the road and make your vehicle more noticeable to other drivers. This practice not only improves your ability to see but also increases the chances of other motorists recognizing your presence on the road, thereby reducing the risk of accidents.

While headlights are also necessary in other situations, such as night driving and sometimes during the day for better visibility, the emphasis on their use in fog and heavy rain speaks specifically to the unique hazards these conditions present.
