When must you use your headlights?

Using headlights is essential for ensuring your visibility and the safety of others on the road. Headlights must be used from sunset to sunrise and when visibility is less than 500 feet due to adverse weather conditions or other obstructions. This rule is designed to help drivers see and be seen, especially in low-light situations or when conditions like fog, rain, or snow reduce visibility.

While it may be intuitive to think that headlights are only necessary at night, this answer emphasizes the importance of using them in any situation where visibility is compromised, no matter the time of day. Similarly, relying solely on headlights during bad weather or only at night neglects specific circumstances where they are crucial for safety, such as during dawn or dusk when visibility might still be poor. Therefore, the comprehensive guideline for using headlights ensures safer driving practices at all times.
