When should headlights be used?

Headlights are essential for safe driving, particularly under conditions that impair visibility. They should be used in bad weather conditions—such as rain, fog, or snow—because these conditions can obscure your view of the road and make it difficult for other drivers to see you. Additionally, headlights are required at night to illuminate the roadway and reduce the risk of accidents. Using headlights in these situations helps ensure that both the driver and other road users can see and be seen, significantly enhancing safety for everyone on the road.

In contrast, using headlights only at night or during daylight hours lacks a comprehensive approach to safety, as other factors like bad weather require their use regardless of the time of day. Similarly, only using headlights when other vehicles are present is risky because there may be instances where other drivers are not within close proximity, but visibility conditions still warrant the use of headlights to enhance overall road safety.
