small roundabouts with two lanes

Oh I've had this dilemma a few times and I've struggled to find a consensus online.

Apply it to roundabouts with two lanes but "no arrows". To the best of my knowledge and unless the road markings state otherwise, if your exit lane is straight ahead (12 o'clock) or anywhere to the left of 12, then you should use the left lane. If you are going straight ahead (12 o'clock) or anywhere to the right of 12, use the right lane.

Basically, my understanding is you can use either lane to go straight ahead (12 o'clock). But you must obey the arrows if the road has them.

I've nearly caused road rage more than once in Roscommon town (loves its roundabouts), as I've used the right lane to go straight ahead including roundabouts where the exit is to the right of 12 o'clock. This is clearly at odds with the line of traffic queueing on the left and with the disgruntled drivers who are forced to let me merge. Just to clarify, there are no arrows on the roads / signs. I continue to do this, so someone please tell me if I'm wrong...

At least that roundabout has road markings going around/through it....

Without lines and 2 entrances people in lane 1 usually get half way through and then suddenly head straight for the opposite exit, completely cutting up lane 2.

I could probably make a 10 minute dash cam video of just that happening!!

You see a gap, enter close your eyes and hope for the best!

Everyone knows that roundabout is a disaster, avoid if you can, say a prayer if you can't.

Looking at Google maps I can't see anything majority wrong with that roundabout, both lanes can go straight through. Seems well marked, the slip road is too short for the cars on the right hand side merging after coming off the roundabout however.

I know what you're talking about. They take a racing line through the roundabout. I see it pretty much daily.

Thats why I think we need lane markings on every roundabout where there is more than 1 entry into said roundabout.. as otherwise people just cut right through on the racing line..

Heres some examples; (2 separate occasions in the same video)

It's fecking infuriating...

As do I, but that is not what happened here.

Here’s the location: R623 - Google Maps. I’ve been sitting at those traffic-lights enough times to know that there’s enough space for two articulated lorries carrying a 40-foot containers to negotiate the roundabout side by side; I was hit by a short rigid truck.

We both entered the roundabout together, me from the right lane in a moving stream of right-turning traffic, while the truck driver from the left lane had a clear path ahead (it’s not actually “straight” ahead, the onward exit is slightly right), and so decided to make his dash for the straight-trough exit. I did hold back, but it wasn’t enough, and with the line the truck was taking and another car right up behind me, my only options were to brake suddenly and risk being tail-ended by that car, or drive up onto the central island of the roundabout to avoid being hit. When the truck did hit the front passenger-side wing of my car, nearly half of my car was already up on the central island...

The roundabout in the OPs example isn't as bad as smaller ones in some towns where sudden dual approach lanes are barely wide enough and the dual lanes on the roundabout are very tight as well. I've had numerous occasions in the past where I've nearly been sideswiped by a car that took the bend too wide/short, or nearly had the side of the car torn off as the other driver tries to squeeze onto the roundabout itself.

There one or two of these roundabouts I have to use regularly and I will sit between the "lanes" to be honest rather than risk the above. Far safer all round than risk the above.

The average Irish driver has no peripheral vision, object permanence or any real knowledge of the rules of the road. They also seem to have a hard time turning the steering wheel and lane discipline is an alien concept. Put all these things together on a tight 2 lane roundabout and all you get is an aneurism for the people who know how to drive properly.

Close your eyes and hope for the best

If there are no markings to suggest this then car on the right has right of way. This falls under the "if no other rule applies then the car on the right has right of way".

Same set up at a crossroads. Left lane for left and straight according to the road markings. Right lane is right and straight according to the road markings. Only one lane coming off the crossroads then left lane giving way to right.

Can you show me this written down somewhere? Surely if this was the case it would make most sense to always use the right lane when going straight on at a roundabout (unless otherwise marked)?
