When are headlights required to be used in Wisconsin?

Headlights are required to be used when visibility is less than 500 feet, particularly in conditions like rain, snow, or fog. This regulation is in place to ensure that drivers can see and be seen under adverse weather conditions, where clarity on the road can significantly diminish. In low-visibility situations, using headlights enhances safety by improving the driver's ability to see other vehicles, pedestrians, and road signs while also making the vehicle more visible to others.

In addition to this requirement, headlights must also be operable during sunset and sunrise, reinforcing their use as a critical safety feature. Keeping headlights on during inclement weather is not just a best practice; it is an essential rule for maintaining optimal visibility and safety for all road users.
