At any time from sunset to sunrise, and every farm tractor upon a highway within this state at any time from a half hour after sunset to a half hour before sunrise; 2. At any time when it is raining, snowing, sleeting, or hailing or during other adverse driving conditions and these conditions do not render a person or vehicle on the highway clearly discernible at a distance of one thousand feet [304.8 meters] ahead; or 3. At any other time when visibility is impaired by weather, smoke, fog, or other conditions, or when there is insufficient light to render a person or vehicle on the highway clearly discernible at a distance of one thousand feet [304.8 meters] ahead.
