As an oldie...
I was taught that unless turning left/ taking the first exit on a roundabout you should indicate right and then signal left to show you are about to exit...

Well I learned in 1986
And was taught that you indicated left on approaching the roundabout when taking the first exit, right on approach when taking the last exit (or if there are more than four turn-offs, any which are require driving around more than 180 degrees of the roundabout to get to), and that whatever the exit you're taking, you indicate left just as you pass the exit before the one you want.

Personally it's the gits who don't indicate at all at roundabouts I want to have killed. And the ones at mini roundabouts who don't indicate right when they're turning right.

I was taught that for first exit be it a one or two lane entry to the roundabout that it was a left hand indication. Going straight ahead was also a left hand lane entry (unless indicated otherwise like the first roundabout in Elgin) but with no indication. Third exit, or right hand exit was a right indication and would either be a straight entry on one lane roads, or where applicable entry from the right hand lane and that the switch should occur from the inside to the outside lane once the 2nd(or straight ahead lane had been passed)
