Re: Indicating on Roundabouts
If you're going left, signal left.
If you're going straight on do not signal on approach but signal left before exit.
If you're turning right, signal right on approach and left before exit.
Obviously there are adjustment to be made for mini roundabouts (don't signal at all for straight on and only signal right when turning right), but you get the drift.
Unfortunately this all requires a bit of thought, but people are generally too busy or too dim to think when they're driving.
