Oh to top it off on that road the lights go red but cars are waiting to clear box, you really need to be watching all sides, front and rear....

If OP won't mind, I have another related question.

Clonsilla Roundabout going from Corduff straight towards South (Luttrellstown).
A roundabout has no clearly marked lanes. Based on the road width, even though two cars could fit, there seems to be only one lane in the roundabout. In practise often drivers enter the roundabout from both lanes same time and end up not sharing the roundabout space properly. Furthermore, there're no narrows on the road before entering the roundabout - guiding which lane can be used for which exit. It means default rules apply in this roundabout: first lane to left and straight (1st & 2nd exits) while second lane to straight and right (2nd, 3rd and 4th (U-turn) exits). Before entering a roundabout, there're two lanes, while exiting on the 2nd exit, there's only one lane. Who has the right to exit the roundabout on the 2nd exit and who should yield?

It wouldn't be a huge problem if traffic is low but during peak times it can be problematic, dangerous, frustrating and all this could be avoided by simply putting proper signage AND road markings. In this case best would be use 1st lane to the left only and 2nd lane to the 2nd, 3rd and 4th exits. I've noticed that in Ireland this lack of signage and poor (I should say outdated) roads', junctions' and roundabouts' design is very common and seems to be extremely ignored.

So what goes here is default....

Left lane is for 1st and 2nd exit, and anything past 12 o'clock is lane 2 so 3rd or 4th.

It means that one of the drivers need to yield while exiting. Who has the right to go and who should yield?
The left lane would as they are in correct lane unless signed or painted otherwise.

Yeah, got that now. Sorry, I just needed to read your answer again to pick up the idea It's pity there are so many drivers who don't consider this and just assuming that if there're two lanes to enter a roundabout, there will also be 2 lanes past a roundabout which suggests that a 2nd lane can also be used for 2nd exit. But that's not the case in this example due to less lanes after the roundabout... Personally to me it's confusing as the lack of signage doesn't give me a comfort of knowing what to expect, how to plan and react accordingly way in advance.

Yeah, left lane there has priority for 2nd exit, but definitely an accident waiting to happen if people aren't familiar with the layout, that could be easily solved with signage/markings. I mean, proper arrows are so uncommon in Dublin, when I've been driving around the likes of Killarney and Galway the lane markings at roundabouts have really stood out to me.

For Amiens street it has to be green car but you can see from street view that cars in the purple cars lane will go straight for the yellow x as traffic in the bus lane will stop them entering the left lane ahead.

The bus lane ends at the start of the yellow box; there is an available lane for cars in the purple car's lane to advance in to.

Purple car is then competing with traffic in the bus lane to its left for that lane, who has right of way there?

It could be argued that as there are 3 lanes on each side of the yellow cars should stay in their lane meaning green car going into the far bus lane.

If not then you've got 3 lanes competing for two lanes.

Yep. And the last thing you want in a road design is people arguing over what should be really, really obvious.

The bus lane has a yield line across it

It's not the orange car anyway.
Green (right lane to right lane)
Purple (left lane to left lane ) - orange follows, or yields to green car if he wants to travel in right lane
When / If there is a bus in the bus lane - it yields to purple ( or yields to green car if he wants to travel in right lane)

Logical.
Simple.

It's a terrible layout, in fairness. Par for the course around that neck of the woods though. The lane markings around the city centre are absolutely atrocious, for the most part. I actually have been meaning to ask what others think of the junction beside Busáras/Customs House when heading Northbound, as the amount of near-misses I've seen here is staggering.





So, 3 lanes (ABC) turns into into 4 (1234) when you get around the corner.

To my mind:
A = 1
B = 2 OR 3
C = 4

The amount of times I've seen A going into 2 or 3 is ridiculous.
Or C going into 2 is another mad move. I'd be interested to hear others' thoughts and opinions, though.

Great example of lack of signage or poor signage in Dublin, and also drivers' whether ignorance, lack of driving experience or lack of logical thinking before they make a maneuver. Plenty of examples such this in Dublin and across Ireland.
