When should headlights be turned on?

Answer: A — From sunset to sunrise and in low visibility conditions

Headlights should be turned on from sunset to sunrise and in low visibility conditions because this ensures maximum visibility while driving. During nighttime, natural light is insufficient, making headlights essential for seeing the road and being visible to others. Furthermore, low visibility conditions, such as fog, rain, or snow, can significantly reduce how well drivers can see and how well they can be seen, so using headlights in these circumstances helps enhance safety on the road. In contrast, turning on headlights only when driving in the rain limits visibility to those specific conditions, potentially overlooking other scenarios that require headlights, such as nighttime driving. Driving with headlights at all times can be beneficial for safety but may not be required by law in all situations. The notion of using headlights from sunrise to sunset may cover some scenarios, yet it doesn’t account for the critical need during times when visibility is poor due to weather or other factors.
