When should you use your headlights during the day?

Using your headlights during the day is crucial in conditions of low visibility, such as fog or heavy rain. This practice enhances your vehicle's visibility to other road users, thereby increasing safety for everyone on the road. In low visibility situations, natural light is insufficient for drivers to see or be seen clearly, making the use of headlights essential.

In well-lit areas, headlights are typically not necessary since the ambient lighting is sufficient for visibility. Similarly, at night, it is essential to use headlights, but the question specifically addresses daytime conditions. Finally, while urban areas may have street lighting that helps visibility, the need for headlights during the day primarily relates to ensuring visibility in adverse weather conditions. Thus, using headlights in low visibility conditions is the most appropriate and safe choice.
