When must a driver use headlights according to Nevada law?

In Nevada, the law requires drivers to use headlights when weather conditions reduce visibility. This includes situations such as rain, fog, snow, or any other circumstance that makes it difficult to see the road and other vehicles clearly, regardless of the time of day. The primary purpose of this regulation is to ensure the safety of all road users by making vehicles more visible in challenging conditions.

Using headlights during adverse weather helps prevent accidents and enhances driving safety. While it is essential to use headlights at night, the law extends beyond that timeframe to ensure visibility during the day in poor weather conditions. Other options do not encompass the broader necessity to adapt to various visibility challenges that a driver may encounter, reinforcing the importance of being prepared for different driving scenarios.
