Here, if you want to turn right, you should put the right indicator before entering the roundabout.

Here you may turn the right indicator just after entering the roundabout.

I never use the left indicator when entering the roundabout, but I do sometimes use it when I'm already on it and am going to make a 3/4 turn or more. It shouldn't be necessary as the right indicator when going to exit should suffice, but I look at it as a further confirmation that I'm not going to exit straight without using my indicator.

I'm not much of a fan of regular double-lane roundabouts either, unless we're talking about those "turbo-roundabouts", which have proper lane markings that move outwards, much like that roundabout of Welland. Example of what I don't like: https://www.google.be/maps/preview#!..._04w!2e0&fid=5

Since you enter a roundabout, which is a one-way street, using the blinkers when entering is non necessary.

Turboroundabouts would fit perfectly there... and in a lot of hideous 2-lane ones.

Actually I don't agree with the general concept of not indicating when following a mandatory direction.

Leaving small roudabouts apart, whose spaces don't make all this blinking possible, we must keep in mind that signalling is a way to communicate not only with drivers, but to everyone on the road.
EG, in a urban intersection, there may be pedestrians who may not know how it works, and it's up to me telling them that I'm going to turn right instead of going straight (so they don't cross my path carelessly).

Following the "one-way" rule, we shouldn't even signal when entering the motorway, since it's obvious where we're going...

The law, at least in Italy, is simple: signal every time you turn (> change road) and every time you change lane (> cross a dotted line). No exceptions are contemplated

Using the blinkers is useful to disambiguate. I can go here, or I can go there. I fail to see the point in signaling when going the only possible way I can go. I'm not saying it is wrong, it's just redundant.

Signaling while entering the motorway is a bit different: it is useful to let people in the motorway know WHEN I want to merge. I can decide to use up all the acceleration lane, so I signal later than if I choose to merge at the beginning of it.

I don't understand this do/don't signal debate at all. Signaling is on roundabouts is just as normal as at other intersections.
If I am entering a roundabout and exiting right, then I signal right. If I am going straight then I dont signal at first but then signal right at the point I am exiting (this lets traffic entering the roundabout see that I am exiting). If I'm going left then I signal left and then signal right at the exit point (this shows traffic entering at 2 points what I am doing. One will have to wait while the other can enter the roundabout). Perfectly logical and curtious. Drivers that don't signal irritate me. They bugger up the flow with traffic waiting unnecessarily.

My driving school teacher used to say that it's mandatory to signal when you change lane or you merge, but not when you turn at an intersection with only a direction allowed (you may or may not signal). At roundabouts we were forced to signal right before exiting (NOT signaling right when entering and NOT signaling left while skipping an exit).

There is not such things like "going straight", "turning right" or "turning left" at a roundabout. There's only entering the roundabout and exiting it somewhere. How do you determine what it's straight, right or left in a roundabout where 5 or 6 roads merge (instead of the usual 4 or 3)?

The same indication principles apply as the example I gave above (for a standard roundabout without traffic lights and yielding from the entry points. In the case a standard 4 point roundabout....which is about 90% of roundabouts). At a 5 or more point roundabout where I would be exiting at, lets say the 4th point, then I would indicate as per the example for going left (left indicator and then right at the exit).
Are you familiar with roundabouts?

Probably half of EU roundabouts are here

What I don't understand is the advantage of signalling you're staying in. The fact itself that you are already in is enough to give way to you; unless you signal otherwise (right), in which case traffic flow can get in faster.

That's a bad rule actually. Drivers or pedestrians might not see the sign that forces you to turn and therefore don't know that you are turning.

People don't always indicate when exiting roundabouts. You never quite know where you stand. Indicating left doing 3-quarters gives an extra security, and people waiting to enter will be well prepared. Like I said before, this system actually works in countries where it's common.

When you are circling around a roundabout you're keeping your road so no need to signaling. When you exit a roundabout you change road so you need to signal. It's like signaling left at every motorway exit to signal that you don't exit there.
