I hate this roadsign.
It means "lanes merging", but to me, it looks like it's saying "There are two lanes now, and in a little bit there will still be two lanes, but one of them will have moved a little bit closer to the other, so you don't really need to worry about anything." Bad User Interface.
I apologize profusely for the bad html and lack of pictures. But my blogging circumstances are less than optimal.
