How to tackle a roundabout
Notice that if you intend to take the first exit (top, left) or the second (centre, left) then the inside lane is for you, because you will not then have to change lanes whilst going round. However, the outside lane (bottom, left) is the right one for you if you are to take the third exit. Always signal your intentions clearly, but not too soon, as you can easily confuse those behind you. However, with signalling, common sense must prevail.
