AIBU to think I have no liability here? (diagram attached)

[WiggyClawsThe2nd]

I think I'm fairly sure on this but can't stop panicking so I thought I'd ask on here.
Friday night I had a car accident. It was a real shock and it's only now that I've stopped to think about it that I'm feeling really really cross.
In the diagram I'm the blue line, the other driver is the green line. The thick lines show where we went, the thin lines indicate where you would have expected us to be going. Given that the lady tried to tell me she'd been going straight on when obviously she didn't makes me wonder if she had a mad moment!
Anyway, this particular roundabout leads onto a bridge over a dual carriageway. On the other side of this bridge you can go left onto a local road, or right to join the dual carriageway.
When we joined the roundabout, the other car was to my left. Neither of us indicated before joining the roundabout, however I did indicate left after I passed the 1st left exit as I was planning to go over the bridge and turn right to join the duel carriageway. As I was about to leave the roundabout the lady turned in front of me to head back round the roundabout and I hit her in the side of the car. Slow speed, maybe 15 mph.
It turns out that we have the same insurance company just to complicate matters.
I'm pretty sure that she is liable for this accident, what do you all think?

YABU: you are liable
YANBU: you are not liable

If she pulled in suddenly she would be facing down the turn off (like when you change lanes on a dual carriage way) not horizontal in the OPs path

Didn't have time. That's why I'm so cross. I slammed on my brakes as she careered across in front of me but neither of us were going fast which just shows how last minute her redirection was

" it suddenly pulled across in front of her into the lane OP had right of way in. "

According to gov.uk the rules in The Highway Code do not give you the right of way in any circumstance.

Surely you are supposed to drive in such a way that you can avoid driving into people even if you think they have made a mistake, ie always ready to take avoiding action.

If it was a standard roundabout then fair enough but it wasn't, the lane the other woman was driving in had ended and the OP did not have to cross any lanes to exit the roundabout. That's a different scenario.

It's funny because there's another trending thread where the OP is being slated for dangerous driving because she changed lanes last minute and caused the driver behind her to slow down to avoid hitting her.

OP you are completely correct and you were in the correct lane. The other driver was completely in the wrong. Although as you technically hit her (even though there wasn’t time to stop) I suspect it would go 50:50 liability.

I guess what I don't understand is why you keep saying she went in front of you when (according to your own diagram), you had to turn sideways into her path to exit the roundabout?

EDIT: I know that her lane had ended and she shouldn't have been there, but I suspect her insurance will argue that you weren't paying attention and just drove into the side of her.

Your diagram doesn't match your explanation - how did she end up in front of you, didn't you turn into her side?

Why do so many people seem to be under the mistaken impression that I chose to drive into the other car. I literally had no warning of what she was going to do, I checked mirrors, where her car was, I indicated, and stopped as soon as she appeared. However by the time she pulled across me, I was already beyond the point where a lane actually existed to continue right.
Similar to if you were driving down a road past a side road and someone drove across in front of you. You wouldn't be able to avoid hitting them, and no amount of awareness of another car sitting at the junction would prevent that.
If she had been changing lanes that would get different, but she cut across a feeder lane at the last minute! No way could anyone have stopped in time!

No one is saying that the other driving was amazing. Both are at fault

Because I was in a feeder lane and that's where it went!!!!!!!!!

If you stopped when she appeared, how did the accident happen?

I was in a feeder lane. She cut across it into a hatched area for whatever reason

It sounds like bad driving all round, tbh. She was in the wrong place, you noticed she was there (stopped apparently?), assumed she was turning and hit her.

Short of stopping in the middle of that roundabout every time I use it just to double check no-one is doing thus again, does anyone have any practical useful advice?
So should I drive onto the roundabout and stop in the feeder lane to carefully check all around?

I think need proper photos with road markings to judge tbh

You might have been beyond the lane, but you were not beyond the other car, in fact she was already in front of you because that's the only way you could have hit her door. Where the lanes went is somewhat irrelevant for your culpability.

Oh for the love of all that's holy, are you lot deliberately misunderstanding? I averted a much more serious incident by braking so promptly and hard.
Don't know why I'm bothering explaining again but the two lanes are both feeder lanes. One on the left, one on the right. It would have been awful driving for her to suddenly swerve into the right feeder lane, it was infinitely worse for her to drive across the feeder lane at right angles to the traffic.

someone done this ito my fil on a roundabo9 not exactly the same but it went 50/50 even thought the other driver cut him up

Not all accidents are preventable - your question was whether you had any liability, and I expect insurance will argue that you do.

That doesn't necessarily mean you could (or should) have done anything differently.

If you knew she was there, on your inside, and travelling at a speed that looked as if she would, or even just might, catch you up and pass you just as you wanted to turn across her path, why did you not slow slightly to make sure she did actually turn, ready to keep on round the roundabout and do a second turn if she didn't turn, ie if she made a mistake? It's up to any traffic behind you to be aware of anything odd happening and deal with it themselves.

Or, were you unaware of what was going on to your left, unaware that she was on your inside, and just turned anyway because you felt you had right of way?

Or, did you see her but insisted on the right of way that you were sure you had and expected her to take avoiding action if she didn't do what you anticipated?

Whichever, you drove into her not the other way round, which would have been much more clearly her fault.

Apologies to those with wise words but I'm done dealing with the trolls.
Thank you so so much to those with industry experience, at least I'm prepared for every eventuality now.
And to those of you who are quite frankly being vile, may you too have a car randomly turn across your lane 😘

Thank you again to the rationalists with useful information and advice!

Feeder lane. Look it up.

Sorry if I’ve missed the explanation, but why were you in the inner lane when your exit was not past 12 o’clock?

That is uncalled for. Wishing people harm is very low.

I don't understand why you asked the question as you obviously know the answer.
