When must headlights be used in Kansas?

Headlights are required to be used from sunset to sunrise, as well as in conditions of reduced visibility, such as rain, fog, or snow. This regulation is crucial for safety, ensuring that drivers can see the road ahead and that their vehicle is visible to other drivers. Using headlights during low-light conditions or inclement weather enhances visibility significantly, helping to reduce the risk of accidents.

In contrast, while it may seem logical to consider constant use of headlights or other specific scenarios, these do not align with state law requirements. Headlights are not necessary from dawn to dusk as conditions are generally adequate for visibility during those times. Similarly, using headlights only in foggy weather is too restrictive and does not cover all the scenarios where visibility is compromised. The requirement to use headlights at all times is excessive, as daytime driving typically allows for sufficient visibility without them. Thus, the correct answer emphasizes using headlights in specific low-visibility conditions for ensuring safety on the road.
