According to Wyoming laws, when must you use your headlights?

Using your headlights from one-half hour after sunset until one-half hour before sunrise is crucial for safety and visibility on the road. This period is defined as nighttime in many states, including Wyoming, when natural light is insufficient for safe driving. Headlights enhance your ability to see the road and other vehicles, and they also make your vehicle more visible to others, significantly reducing the risks of accidents during low-light conditions.

While it is important to use headlights during other situations, such as inclement weather or when visibility is poor at any time of day, these scenarios are not the primary focus of the law. The specified time frame mentioned in the correct answer ensures compliance with regulations designed to protect both drivers and pedestrians when light conditions are minimal. Thus, utilizing headlights during the designated times is both a legal requirement and a critical safety measure.
