When should headlights be turned on?

Headlights should be turned on during adverse weather conditions such as rain, fog, snow, or sleet, as well as at sunset until sunrise. This practice enhances visibility not only for the driver but also makes the vehicle more visible to others on the road. Adverse weather can significantly impair visibility, making it challenging to see other vehicles, traffic signals, or road signs. Furthermore, using headlights during the hours of darkness ensures that drivers can see clearly and that they are seen by others, which is crucial for safe driving.

In contrast, relying solely on headlights at night or in dark areas can limit the safety margin that headlights provide in various weather situations. Additionally, using headlights based solely on vehicle speed does not account for conditions that may require additional visibility. Likewise, limiting their use to heavy traffic ignores the potential dangers in less congested environments where visibility is still crucial. Overall, proper use of headlights is essential for driving safety.
