When must drivers turn on their headlights?

Drivers are required to turn on their headlights when visibility is poor, such as during fog, heavy rain, or snow. This is crucial for safety as headlights improve the driver's ability to see the road and their surroundings, as well as making the vehicle more visible to other road users.

In conditions where visibility is significantly reduced, the use of headlights helps prevent accidents by ensuring that vehicles are seen from a distance, allowing other drivers to make safe decisions regarding distance and speed.

Headlights are also essential for maintaining an acceptable level of visibility during twilight hours or when driving through shaded areas, ensuring that drivers can adequately perceive potential hazards. While some may think headlights are only necessary at night or in specific urban settings, the broader requirement during poor visibility conditions emphasizes the importance of safety at all times on the road.
