When should you use your headlights in relation to the weather?

Using your headlights during rain, fog, and other low visibility conditions is essential for enhancing your visibility to other drivers and for improving your own ability to see the road. In these situations, natural light may be insufficient, and headlights help you navigate safely. During rain, for instance, headlights can illuminate the road better and make you more visible to oncoming traffic, reducing the risk of collisions.

In fog, it is particularly important to use low-beam headlights, as high beams can reflect off the fog and create a glare that can obscure visibility further. Therefore, using headlights in these conditions is not only a best practice but often a legal requirement. It ensures that you are driving as safely as possible, taking into account the impact of weather on visibility.

The other options do not cover the full context of when to use headlights effectively. For example, only using them at nighttime neglects the importance of visibility during various weather conditions. Similarly, restricting headlights to when it is snowing or only while traveling on highways ignores the broader need for safety in low-visibility situations.
