When must headlights be turned on while driving?

Headlights are required to be turned on 30 minutes after sunset as a safety measure. This rule is in place because visibility can significantly decrease just after the sun sets, even while there may still be some natural light. Turning on headlights during this time helps to ensure that drivers can see the road clearly and be seen by other vehicles and pedestrians, reducing the risk of accidents.

The requirement does not allow drivers to wait until it is completely dark because that could create dangerous conditions on the road. Instead, by using headlights at the specified time, visibility is improved for everyone. This also aligns with the principle of being proactive about safety when transitioning from daylight to nighttime driving conditions.
