Under what conditions should you turn on your headlights during the day?

Turning on your headlights during the day is important for visibility and safety, especially when conditions are poor due to weather or other factors. This includes situations with rain, snow, fog, or any other circumstance where the visibility is significantly reduced. By activating your headlights in these situations, you increase your visibility to other drivers, making it easier for them to see you, which can help prevent accidents.

Driving on highways, while it may be beneficial to have your headlights on, doesn't specifically address the need for headlights when visibility is inadequate. Turning on headlights only at nighttime does not take into account the various daytime conditions that can call for more visibility. Similarly, relying solely on the headlights of other vehicles doesn’t ensure your own visibility in poor conditions. Thus, the recommended practice is to turn on headlights whenever visibility is compromised, ensuring safety for yourself and those around you.
