Digital lane closure signs have been installed on highways in my city in the past week. You don't really notice them during the day as they're just
black but they were testing them yesterday at night and I saw the green arrows for open. Also there was digital text stating " Give extra space with
each other and on the road" that leads to to believe that some sort of check point is in store bc why else do we need to give space on the road unless
we're going 1mile per hr in a traffic jam
