When must a vehicle's headlights be switched on?

The requirement to switch on a vehicle's headlights at any time of day when visibility is less than 150 meters is grounded in ensuring safety on the road. Poor visibility conditions, such as fog, heavy rain, or darkness, can make it difficult for drivers to see other vehicles, pedestrians, and road signs. By using headlights in these situations, drivers can improve their own visibility as well as that of their vehicle to others, reducing the chances of accidents.

This regulation is applicable regardless of the time of day; hence, it is essential for drivers to be proactive about their lighting in any instance where the ability to see is hindered. This encompasses more scenarios than just the typical dusk-to-dawn timeframe, making it a comprehensive safety measure.
