Avoiding queuing traffic at roundabout by using the incorrect lane and doing a full circle of the round about is not allowed!!! I definitely read that somewhere and i also got a ticket when I tried it at the Tyne tunnel years ago ( must have been about 2003/2004. Although i cant seem to find it on the net. I would say though Adrian if you were driving and the lane on your right was right turn only but someone overtook you causing to to break because they fancied going straight on you wouldn't think the was ok??? The lane the bus was clear marked right turn retail park. the bus ended up not only stopping on the roundabout almost causing a crash but went to the metro centre which is clearly marked as the inside lane.
