What does North Carolina law require regarding headlights during daylight hours?

North Carolina law mandates that headlights must be used when visibility is less than 400 feet. This rule is based on ensuring safety during conditions where drivers may not be able to see other vehicles or obstacles clearly. It is particularly relevant in scenarios involving rainy weather, fog, or other factors that could impair visibility, thus enhancing road safety.

The law is designed to promote better visibility and make vehicles more noticeable to other drivers and pedestrians, reducing the risk of accidents. Using headlights when visibility is compromised is not just a legal requirement but also a proactive measure to help ensure that all road users can navigate safely.

In contrast to this, simply operating headlights at night or not using them in clear weather does not address the need for visibility in various driving conditions. Hence, the law focuses on maintaining visibility standards at all times, especially when conditions warrant extra caution.
