Indicating on roundabout approach

BarraOG

Hi,

When living abroad I was taught that you indicate left having just passed the exit immediately before the exit you plan to exit from. Furthermore, if you are going to be taking the first exit, then you indicate left while approaching the roundabout. If going right in the roundabout, you do not indicate right on approach.

With regard to passing my driving test in Ireland, do I ever need to indicate right when approaching a roundabout, and if so why?

Thanks,
Barry

You should indicate right approaching the roundabout, (I let it auto cancel on the turn). Then indicate left to change lane or when passing the exit immediately before yours, whichever comes first.

Taking any later exits (those past 12 o’clock – right)
Approach in the right-hand lane (unless road markings say otherwise), indicate
‘right’ on your approach and leave your indicator on until you have passed the
exit before the one you intend to take. Then change to the ‘left’ turn indicator.
Move over towards the left on the roundabout and continue signalling left to
leave.

I'd argue that graphic is wrong. Lane change should be at/immediately after the previous exit, as otherwise you are turning sharply across traffic that could be coming from 12 to 6 o'clock, (i.e. straight on for them). Especially in this country where if you give anyone an inch of space or split second headstart they will be in that space undertaking you as you try to exit.

Hi,

The above is not a great example, the right indicator is cancelled too early, should wait until too late to turn into the 12 o'clock exit, (Centre line) then switch immediately to left indicator. (Could confuse someone at waiting to enter at 12 o'clock)

Also the diagram as it stands is wrong. The left lane is clear therefore the car should have exited in the left lane.

The graphic is correct. You should not 'change lanes' on the roundabout itself, and only change from the r.h. lane into the left one once you're on the new stretch if road away from the roundabout.

The reason is simple: there are two lanes off the roundabout to allow increased traffic flow through it. The person approaching it in the graphics PLUS any one of the other two lanes can all use the same exit simultaneously. If you though migrate from one lane to the other and merge into the l.h. lane you are actually impeding traffic from two other sources. If that's on your test you should fail it.

That's incorrect. Exiting across the left lane as indicated by the graphic is dangerous. The instruction I quoted above from the rules of the road is very clear about positioning.

Hi

Have heard this "Rule" a few times. One thing confuses me

If you can not change lanes on a roundabout how can anyone ever use any "Inside" lane.

Is it some kind of d a one-way valve system. Cars can flow from the outside to the inside but can not flow back.???

As I asked in my previous post, please supply a link

They should be waiting till it's clear. Also the reason for maintaining the position presented in the graphic is for someone from there who may be on your inside blind spot also taking that exit, as well as someone entering from where you've pointed to, who only wants to take the first exit to them.

If you look at the lane markings on the example above, you are continuing in the same lane to exit the roundabout. The rhl also exits

If there is only one exit lane then a lane change would need to occur

Which is typically a merge after the exit.

I fully agree with you regarding the graphic being wrong. I am shocked at the number of people who do as the graphic shows. Doing as the graphic shows is akin to taking left turn from the right hand lane of a two lane road - which would be totally illegal.

Hi,

But please explain. when the car entered the roundabout, it changed from the outside lane to the inside lane. why is this OK and it is illegal to change from the inside to the outside

I don't think he said that. He was talking about best advice to reduce risk of hitting something you can't see behind you by continuing on the lane you are in, and changing lane after the Round About.

The way to reduce the risk is to change lanes correctly on the roundabout. Granted there are a few small ones where two lanes have been sqeezed in and this isn't always possible in which case of course exit in the right lane.

But as a normal manoevre, changing lane at or about the exit before yours is correct. Otherwise you're exiting into an overtaking lane while not overtaking anyone which is illegal (and slows traffic down, causes undertaking, and contributes to accidents)

You are copying something completely different to what I Responded to you on. That also says towards the left of the round about. Roundabouts with multiple lanes, have the relevant lanes lead into the exits also. This will be present for the second lane (as shown in the graphic). So in most cases (unless sign posted earlier) there is no need to change lanes to exit.

Think about how you do what you've just said here. To check the 1st lane is clear, when moving into it from the second lane in a round about, you will need to put your chin over your shoulder to look behind you, losing any visibility of what's in front of you.

Do the lane change after the exit. That's why they've usually got 2 available after the round about.

But you are changing lanes. You are crossing the outside left lane and you must give way to any traffic in that lane, which of course means that you must first check to see if it is clear.

Now when you are safely off the roundabout after crossing the left lane on the roundabout, you must now do another lane change and "you will need to put your chin over your shoulder to look behind you, losing any visibility of what's in front of you."

So instead of one lane change you have to do two.

I'm not quite sure where you're going with this. You may cross over a lane without changing into it. Which is exactly what you've just described here. The graphic shows that you remain within your lane when exiting. The road markings will show your lane crosses over.

At a round about you are supposed to give way to traffic to your right, that also refers to cars in the 2nd lane. But that does not mean you go into the 1st lane when preparing to exit.

When I'm changing from the 2nd lane to the 1st lane on a straight road, I've no need to put my chin over my shoulder. I can watch where the car is, that I've passed by in my side mirror while still having visibility ahead of me.

Hi,

Sorry, was being little facetious when I copied pasted your quote. There is of course no need to give a full blind spot check when changing lanes on a dul carriageway, only a shoulder check.

However, you must still give way to traffic in the outside lane, irrespective whither you are just crossing, or driving in it for a few meters.
