Multi-lane roundabouts

That's just nonsense and would slow the flow of traffic. In particular for those turning left.

Are you unable to merge? What do you do when a dual carriageway reduces to a single lane? It rhymes with verge. :pac:

Apply the same rule for roundabouts reducing from two to one lane.

It's hardly "nonsense" when it's the rules of the road!

I'll let you search the rules of the road so you can correct your opinion. You can be in either lane going straight (or 12 o'clock) where there are two lanes. The rules of the road (website here) even have a picture of this exact situation.

All of the pictures show two-lane exits, with the right-hand car NEVER cutting across or merging on exit.

Jaysus, we're going around in roundabouts here....:pac:

As per my post above, you can't know how many lanes are at the 12 oclock exit unless you are an all powerful being or have used the round about previously.

So you can approach in the right lane to exit at 12, as more than likely there's a second lane on the exit you are taking. Or alternatively, not realise there's no second lane, or even better a single lane with a merge arrow!

You can NEVER cut across anyone in this situation. Should I keep including the word merge in my post? IN what situation are you cutting across someone?

Unless as per the OPs original post, another driver has made an error and entered the roundabout when it wasn't safe to do so.

And again you're incorrect; that assumption is a million miles from the truth.

OK thanks for correcting me. :rolleyes:

No problem. In fairness to you, you may only be familiar with an area where most roundabouts do have 2-lane exits.

Just pointing out that it's not a safe assumption to make that "most" do, or that they're "more than likely" to have 2.

ct5amr2ig1nfhp

I (un)fortunately have to travel for work purposes, so my assumption is based on experience. Most exits from a two lane entrance, will either have a two lane exit or a merge at '12 o'clock.

When in doubt, obey the default rule; left lane for 1st & 2nd exits, right lane for all others.

This rule, which comes from "Rules of the road" leaflet, has no backing in the law. I have no idea where it originates from...

Try checking Google maps on any of the ring roads around Limerick.

That was the original when I did my test 25 years ago. They've only succeeded in totally confusing it ever since. That 12 o'clock rule is one pile of shyte. Problem is, because most people don't have to sit their test again, they never know the rules have changed.

First and second exit you take the left lane 3rd and subsequent exits you stay right? That it?

That was the rule anyway, unless there are 2 lanes on exit, or unless there were signs instructing otherwise.

The "12 o'clock" version of that started off as a related shorthand way of saying it for bog-standard (single lane exit ) roundabouts, but it immediately confused the fcuk out of everyone who didn't have a satellite view of the upcoming roundabout and they started adjusting it arbitrarily - and with no basis in law - to 12:30 and 1:00 based on guesswork and whether or not they'd have to queue in the left lane.

There should definitely be more arrows for roundabouts in this country. One particular r/a near me, some drivers think the right lane is for going straight on even though its a single exit.

ct5amr2ig1nfhp

Say for arguments sake that 50% of single lane exits have a merge arrow (two lanes entering the roundabout), and the other 50% do not.

Would it not be wise/safer to assume that a car might use either lane to go straight ahead/12 O'clock/2nd exit? You cannot have a situation where there is one rule for 50% of roundabouts and another rule for other 50%.

A what now ?

What kind of roundabouts do you get to drive on ?

Arrows on exits AND double lanes ?

And the same thing applies as earlier; even if such things as "merge arrows" DO exist (and I presume they do, somewhere, since you've obviously seen a few) how would someone who'd never been there before see it from the other side of the roundabout when entering ?

I think you should have moved into the left lane earlier, at the latest after passing the exit (time 0.38) prior to the exit you wanted to take.

ct5amr2ig1nfhp

Yes... two lanes entering the roundabout, "one" lane on exit with a merge arrow. i.e. the exit lane has two lanes for about 1 meter and a merge arrow.

Edit: Here yee go. I have attached a screen grab from Google streetview. left side is the exit showing the merge nearly immediately after taking the exit. The right showing an *example* of the two lane entrance. There are four entrance/exits on the roundabout and they're exactly the same as per the pic.

That's mad! I've never seen that before coming off a roundabout.

And...?

You were crossing a dashed line and changing a lane, any collision would be only your fault.

You shouldn't change lane when on a roundabout, if it is a multi lane roundabout you enter the correct lane when coming into the roundabout. Quite simple.

Not sure if you are trying to sound so uneducated about driving properly or just trying to create an argument?

No, he's not at fault, the car should have waited for the roundabout to be clear, you can't just drive out in front of cars.
That car had no idea where he was going, could have been carrickmines, could have been ballyogan rd, could have been m50 north.
Other car should have waited

The car in question entered the RB in a safe way.

It is the cameraman that is changing a lane later without making sure there is sufficient room to do so.

Decide yourself, I'm easy.

RB is essentially a curved one way street, with all rules applied. You take the inner lane, you just ask for trouble.

Source? The reason I ask is that I think that *should* be the case, but there are many roundabouts e.g. Donabate, where this is not the case, as lanes 'split' after exits.

Ideally yes, but in Ireland I have seen only a handful of such roundabouts - they are called turbine roundabout.



The rest is very old, inefficient design...

Quite obviously not. I think I've seen it on two roundabouts ever.

Firstly, I didn't change lane, I entered the roundabout in the correct lane, continued to the exit I intended to take, which was a 2 lane exit, and tried to take the exit, exiting from the right hand lane on the roundabout, to the right hand lane of the exit

No where did I cross a dashed line, or change lane.

I think you need to learn the correct way to use a roundabout
