When must the lights on your vehicle be turned on during the day?

The lights on your vehicle must be turned on during the day when persons and vehicles cannot be clearly seen for 750 feet. This regulation is in place to enhance visibility and ensure the safety of all road users. When visibility is diminished, such as due to weather conditions like fog, rain, or other factors, having operational lights allows other drivers, pedestrians, and cyclists to see your vehicle more clearly, reducing the risk of accidents.

While there are specific circumstances when you might need to use your lights, such as in fog to improve distance visibility or when approaching another vehicle, the requirement to have your lights on at 750 feet encompasses a broader range of visibility issues. This rule aims to provide a standard measure for when additional visibility is needed to maintain safety on the road.
