What is the requirement for headlight use during rain?

The requirement for headlight use during rain emphasizes the importance of ensuring visibility and safety on the road. When windshield wipers are in use, it indicates that visibility is compromised due to rain. Turning on headlights during these conditions helps illuminate the road ahead and makes the vehicle more visible to other drivers. This practice is especially crucial because rain can create hazardous driving conditions that reduce visibility beyond what might be apparent.

Using headlights in conjunction with windshield wipers aligns with safe driving practices and many state laws, as it enhances overall road safety. This requirement encourages drivers to be proactive about their visibility and the visibility of their vehicles, helping to prevent accidents during inclement weather.
