Signals and position. When taking the first exit, unless signs or markings indicate otherwise signal left and approach in the left-hand lanekeep to the left on the roundabout and continue signalling left to leave. When taking an exit to the right or going full circle, unless signs or markings indicate otherwisesignal right and approach in the right-hand lanekeep to the right on the roundabout until you need to change lanes to exit the roundaboutsignal left after you have passed the exit before the one you want. When taking any intermediate exit, unless signs or markings indicate otherwiseselect the appropriate lane on approach to and on the roundaboutyou should not normally need to signal on approachstay in this lane until you need to alter course to exit the roundaboutsignal left after you have passed the exit before the one you want. So, the text doesn't actually say that when taking any intermediate exit ie: straight on, that you should get into the left hand lane? Select the appropriate lane on approach, unless road markings indicate otherwise. In the illustration it doesn't show the road markings, but on the majority of roundabouts the left hand lane will have an arrow indicating left and straight ahead, and the right hand lane will have an arrow showing right and straight ahead. Unless the road markings show otherwise, then both approach lanes will be appropriate for going straight ahead.
