In Maine, when are headlights required to be on?

In Maine, headlights are required to be on from sunset to sunrise and in any condition of reduced visibility. This requirement is essential for ensuring the safety of all road users during low-light conditions and adverse weather scenarios. When visibility is compromised due to factors such as rain, fog, snow, or even heavy traffic, having your headlights on helps improve your visibility and helps other drivers see you.

The point about having headlights on from sunset to sunrise is critical because those hours are typically when visibility is significantly decreased. It is a common safety regulation across many states, not just Maine, recognizing that driving in darkness can be hazardous without proper lighting.

Other options, such as only requiring headlights during foggy conditions or heavy rain, do not encompass the broader requirement of enhanced visibility regulations. Limiting the use of headlights to specific weather conditions fails to account for the variety of scenarios that can impair visibility on the road. Therefore, the comprehensive nature of the requirement captures all situations where additional lighting is necessary for safety.
