When must headlights be turned on when driving in Maryland?

Headlights must be turned on from sunset to sunrise and during any situation of poor visibility, which makes this answer the correct choice. In Maryland, the law requires that headlights be lit not only during nighttime hours but also whenever visibility is compromised. This can happen due to various factors such as fog, rain, snow, or other conditions that obscure vision. By ensuring headlights are used in these situations, drivers can see better and be seen by others, enhancing overall road safety.

In contrast, turning on headlights from sunrise to sunset is not sufficient, as visibility can remain low during the day due to weather conditions. Nighttime driving without headlights is dangerous and puts both the driver and others at risk. Simply relying on streetlights does not guarantee adequate visibility, as streetlights may not illuminate all areas effectively, especially on rural roads or during inclement weather. Therefore, the combination of sunset to sunrise usage and during poor visibility ensures compliance with safety regulations and promotes safer driving practices.
