When must you turn on your headlights?

Turning on your headlights from half an hour after sunset to half an hour before sunrise is crucial for safe driving and is a requirement in Massachusetts. This timeframe is often referred to as "legal twilight" when visibility decreases significantly as the sun sets and just before it rises. During these hours, using headlights enhances visibility for you and other drivers, making it easier to see the road, pedestrians, and other vehicles.

Using headlights during these times not only helps you see better but also allows others to see you, reducing the risk of accidents. It’s important to keep in mind that while there are specific visibility conditions that also require headlights, the general rule during twilight hours promotes safer driving practices overall. Other options suggest conditions that are less comprehensive in scope, neglecting broader periods where headlights are necessary for safety.
