When should a driver turn on their headlights?

Turning on headlights in low-visibility situations is a critical safety measure for drivers. Low visibility can be caused by various factors such as fog, heavy rain, snow, or dust storms, making it difficult for drivers to see the road ahead and for others to see the vehicle. Headlights enhance visibility for both the driver and other road users, thereby reducing the likelihood of accidents.

The law in many areas requires drivers to use their headlights in conditions where visibility is less than a certain distance, often specified as 500 feet. This use of headlights not only improves safety but also helps in making the vehicle more conspicuous to others, which is especially important during adverse weather conditions that impair sight.

While headlights are essential at night, they are equally important during the day when visibility is compromised. This understanding emphasizes the significance of adapting driving behavior to the environmental conditions rather than adhering strictly to a schedule defined by day or night.
