When must headlights be used in Maine?

Headlights must be used from half an hour after sunset to half an hour before sunrise in Maine because this time frame corresponds to periods of reduced visibility when natural light is insufficient for safe driving. By requiring the use of headlights during these times, the law aims to enhance visibility not just for the driver, but also for other road users, such as pedestrians and cyclists, thus improving overall safety on the roads.

While there are regulations pertaining to the use of headlights in different conditions such as fog, rain, or during the day, the primary timeframe for mandated headlight use is focused on the transition periods around sunset and sunrise when visibility can be greatly diminished. This emphasis on low light conditions is a common practice in driving laws to ensure safer travel at crucial times when accidents are more likely to occur due to visibility issues.
