Re: two lane roundabout laws
 

The highway code is not the law, it is a set of guidelines, a best practice if you will, however clearly states where a rule is also governed by law, such as in rule 188.

For your issue, I would say you were both in the wrong, but more the other party than yourself. Using The Road - Roundabouts read rule 186. If taking an exit to the right (doesn't matter how many exits), approach in the right lane and indicate right. For intermediate exits (you), select the appropriate lane. It's fair to say that although technically you should have been in the left lane, your lane was still appropriate, as no road user should have been turning right from the left lane, indeed, as you say he was indicating, his lane discipline is worse than yours, as the rule is much clearer in this regard.

Re: two lane roundabout laws
 

Some spastics decided that on some roundabouts the right hand lane should be used for straight on, but that's apparently signposted every time.
Highway code ain't the law but if you go right from the left hand lane you'll get pulled over I'd imagine.

If you're going straight on and there's two lanes on the exit, it'd be reasonable to be in the right hand lane to use the right exit, on the assumption (they kill, i know) that anyone in the left lane has brains enough not to go right, and even if they're going straight on, wouldn't move over to the right hand lane without checking their mirrors and blind spots. I do it as many others do, but it depends on the roundabout as well i guess.

Having "Brains enough" is a rare commodity among some drivers--there lies the problem

Re: two lane roundabout laws
 

I work on an industrial estate and the main roundabout has dual carriageway up to it and on the left and straight ahead junctions. Kn0bheads are coming up on the right hand lane then turning left. Sometimes without any indicating. Given that the straight ahead dual carriageway is a link berween the A5 and M1 you can imagine there is a lot of traffic that goes straight on from the left hand lane, and rightly so. Seen many a close call, and I always worry if a bike is filtering that a vehicle doing what I believe is an illegal move, will have them off.

Re: two lane roundabout laws
 

If it's two lanes on and two lanes off then of course you can use either to go straight on (assuming a typical 4 exit roundabout and no signs or road-markings to dictate otherwise).

The taxi driver made a dumbass move and probably at the last second realised it wasn't his exit, maybe you should infer that to your insurers. It's unpredictable behaviour and there isn't a great deal you can do about something like that, lifesaver or no lifesaver. It's akin to a lane-swap from the taxi driver without so much as a glance.

Re: two lane roundabout laws
 

Because it shows the guy in the car coming up to the roundabout that you're carrying on round it, and prevents them running straight into the side of you as you head for that third exit.

... then you nudge "left" to show where you're coming off

Not signalling is one of my pet peeves with regards to roundabouts.

Re: two lane roundabout laws
 

I was under the impression that you indicated your intention on joining, ie left if you are taking the first exit no indication if you are going straight over, or a continuing right if you intend to be taking the 3rd+ exits.

You then indicate left to show your intention to leave the roundabout once you have cleared the exit that proceeds the one you intend to take.

for most roundabouts there are no hard rules, convention dictates the lh lane if you intend to take the first exit or straight on. the rh lane if you intend to go straight on or take a right hand exit.

traffic in the first lane, should expect traffic in the second to attempt to exit if it is a two lane exit. However, traffic in the second lane should not cut traffic in the first. so my interpretation is. If you are in the second lane and intend to exit into the right hand lane of an exit. It is your duty to make sure your exit is clear. You are the one making the manoeuvre. The idiot to your left does not have to let you across his path.

Re: two lane roundabout laws
 

Izzy---Fine idea but the rule is indicate when you are turning off and give priority to vehicles already on the round about. If you are both going straight over the roundabout you having past the first exit would have your indicator signalling left that you intend coming off anyway
If your intention is to take the third exit you will be signalling from the the second exit that you intend coming off at the third exit
Taking the senario you are on the roundabout with the intention to take the third exit and the other vehicle is approaching the second entry to the roundabout
both vehicles approaching the roundabout from directly opposite directions
When your vehicle is seen by the vehicle from the opposite direction he does not know if you intend continuing round to the fourth exit if you have your r/h indicator on. Due to his line of vision your indicator is only visible on the approach towards him ,the transision between r/h and l/h happens when you are side on to him and if the only indicator he sees is your l/h indication he should have no doubts about your intentions where as if he has only seen the r/h indicator he may try and filter in on your left and you end up cutting directly across the path of your exit.

Sorry it is very hard to expain

Re: two lane roundabout laws
 

We agree the person doing a lap of the roundabout in the outside lane is an idiot, but if it's a two lane exit then it's hard to predict that someone could do this, no matter how diligent and aware you are. Even if they were alongside you from the entry to the exit, you can only assume they're taking the left hand lane straight on.

You don't hold back when alongside someone at traffic lights because they'll possibly turn right from the left hand lane.

It would be their fault entirely if they, for some reason, chose to exit in the right hand lane straight on (making a bizarre late lane change) and you were already there, so what's the difference here? Surely you can't just choose to use only the outside lane of a major roundabout whatever your intended exit and not be at all culpable when the inevitable happens.

Re: two lane roundabout laws
 

From the perspective of someone approaching or waiting to enter the roundabout, no indicator or right hand indicator from traffic on the roundabout means pretty much the same thing - that he's not gonna take the next exit. However on many roundabouts you have visibility further than just one junction, so it can be useful.

But as you're approaching the roundabout, intending to turn right, you should be indicating right anyway. So in order to not indicate right, you have to deliberately cancel your indicator once on the roundabout, which is quite unnecessary.

What i'm saying is, you have to perform an extra action to not indicate. Why bother?
