Selected Roundabout Tutorials
Basic roundabout video.
This video by East End is a good introductory to roundabouts. It shows the mirror signal manoeuvre routine. How this MSM routine is applied when approaching the roundabout.
The sound quality is however relatively poor. However the simplicity with which it is presented makes it a good introduction to the signalling process on the approach. The major fault however is that it does not highlight the fact that you have to change your signal to an exit signal at the exit prior to your exit.
