When are headlights required to be turned on?

Headlights are required to be turned on during low visibility conditions or after sunset to enhance visibility and safety for both the driver and other road users. This includes situations where weather conditions such as rain, fog, snow, or even heavy overcast can significantly reduce the distance a driver can see ahead. By using headlights in these situations, drivers improve their ability to see and be seen by others, which is crucial for preventing accidents.

It is important to note that while headlights are indeed used at night, they are also essential during the day in low visibility situations. This makes turning them on based on visibility conditions practical, ensuring safe driving practices regardless of the time of day. Therefore, this choice reflects a comprehensive understanding of when headlights should be used for optimal safety on the road.
