When should headlights be used while driving?

Headlights should be used in various conditions to enhance safety and visibility for both the driver and other road users. It is crucial to use headlights in foggy or rainy conditions, as these weather conditions can significantly reduce visibility. The illumination provided by headlights helps improve the driver's view of the road and makes the vehicle more visible to others, thereby reducing the risk of accidents.

Additionally, using headlights during the day can also be beneficial, especially in situations where visibility is compromised, such as in overcast weather, at dawn or dusk, or in areas with heavy traffic. Some jurisdictions even encourage or require the use of daytime running lights for safety reasons.

This combined understanding emphasizes that headlights are not solely a nighttime feature but are necessary during various conditions to ensure safe driving practices. Therefore, using headlights in both foggy or rainy conditions and during the day supports overall road safety and is in line with best practices for driving.
