Little known detail

So guys, I have often wondered why they leave a gap in sign of a roundabout, as shown above, and so I went to find out. Any ideas? Is it that there is no road there? Maybe you have to leave the roundabout before it? Well it’s actually very simple. It’s simply to show you witch way you need to go around a roundabout. It’s especially aimed at foreign drivers who may be driving on our roads. Maybe those Americans we hear so much about causing a ruckus lol. So now you know. Great pub trivia lol.
