Yes, the rule at any roundabout is give way to traffic on your right i.e. vehicles already moving around the r'about.
When there is a gap move on to the roundabout and then either leave the system entirely or head for the next one in the sequence until your planned exit presents itself.
Generally speaking it works well although I have experienced moments when I thought that I would be doomed to haunt it for all eternity.

There's a cracking three-wheeler at the foot of Marlow Hill ...

This one?



I hate going round that place. It's like 'Death Race 2000' at times.
My dislike of it might be coloured by the fact that if I'm there it's always in connection with a hospital visit.

That's the one! Though it is the roundabout at the top (Handy Cross?) which gives me the horrors. I had to negotiate it daily for a week in summer 2015 when the roadworks for the Waitrose access roads etc were at their worst. Local drivers were like angry wasps because of the roadworks and I had to try to pick out the right lane to exit to Marlow Bottom (fnarr fnarr) which, as all locals tell me, is impossible.

Handy Cross it is! Haven't been around that one in years, I'm pleased to say.
My real beef with Marlow Hill is that it is either almost at a standstill and no-one will let you out from the hospital site, or traffic is fairly light but comes down the hill so fast it suggests an attempt at the land speed record may be underway and you still can't get out!

My venerable uncle lives near the top of Marlow Hill and we visit home when Mr Limey and I are at Band Camp (which takes place out along the Hughenden road). But I had to get to Marlow Bottom because we were Beer Monitors for a particularly thirsty camp and I had to get regular supplies from the Rebellion Brewery.

In Luxembourg we have this turbo roundabout


Up to four lanes in the roundabout
Expresslanes when you will take the closest exit
Tunnel to go underneath the roundabout
traffic lights to avoid complete breakdown of traffic and blocked lanes
and now they are building a tramway going over the roundabout

It's a complete nightmare

Yikes! JFK getting love in Lux...

OMG I have just now realized they're a spiral. Are all major roundabouts that way, where the inside entering lane is actually entering a whole new lane that didn't exist before because the lane heading toward it shifts out one as they pass?

[glatt]

One problem with roundabouts is they are hard on pedestrians.

You can have crosswalks like half a block away from the roundabout, but then you are making the pedestrian walk half a block one way and half a block back again just to cross the street.

Roundabouts, the stuff that movies are made of.

In the state known for its fantastic process for turning left ;-)

They are starting to be used more here in metro Kansas City. I hate them, but I understand their purpose. Also becoming popular at highway exits is the diverging diamond.

Do you know more turboroundabouts in Luxembourg?
I have made a map of all turboroundabouts world wide (see: http://www.dirkdebaan.nl/locaties.html OK, it's in Dutch).
You will help me with your answer.

There's one more coming this year :

It's called "Irrgärtchen", that means "little maze".
