Roundabout collision - who is at fault? With diagram

I'm sure that they say anything past the driver seat it's the rear of the car so if you're hit beyond this point it's the other driver at fault

As an instructor.... Blue car.
But again i wasn't there to see speeds etc....
Problem being is everyone in too much of a rush to get nowhere fast.

Slow down .. Read the roads your driving!!!!

Thats a simple one tbh, if youre already on the roundabout you have right of way. The blue car is at fault.

I always check my nearside wing mirror for idiots if I am exiting a roundabout from anywhere other than lane 1. But I don't think Red could have seen this idiot in time, because he emerges so close to the exit he would have been in Red's blindspot. It would have been so interesting to see video!

That's a good outcome, in my opinion. You did absolutely nothing wrong and the accident was the other driver's fault, but insurance companies often seem to settle collisions on roundabouts as 50/50 blame, especially in the absence of evidence e.g. dashcam footage.

This happened to me as well but i was lucky and swerved into the third lane before he hit me. I was just very very lucky there was noone in or coming up in the third lane i was so angry though as there was no need for that driver to nearly cause an accident for no reason

@Notcheekyvimto it was the overhead view I was asking for, which someone else has since posted.
Having seen that, I can see it is exactly how I imagined from your description and previous photos.
I don't think you did anything wrong!

Surely it's obvious from this picture that blue is totally at fault. There are 2 lanes approaching the roundabout and 2 lanes exiting it (at the exit red is taking, at any rate). Red remains in the same lane throughout and correctly executes the manoeuvre.

Blue might have got away with pulling onto the roundabout carefully when they did IF they were going to exit left (ie the same exit as red is taking). But the minute they want any other exit, straight across or turning right, they are in the wrong lane and are undercutting red.

Where red hits blue is completely irrelevant in this instance, because blue is in the wrong lane and has to wait for any car which is in the correct lane and approaching from blue's right, as they have priority.

I don't think this os classed as changing lanes.
It's a roundabout with two lanes marked...you have to cross lanes to enter/exit that's not the same as changing lanes.

Even IF the blue car did not think the red car was leaving at that exit, based on position it should have been obvious red would immediately need to change lanes or exit across their path so joining alongside/slightly in front was always going to create a problem.

@Collaborate

The red car did change lanes by crossing over the outside lane to get off the roundabout.

But it didn't. There are two lanes going off at the roundabout. The red car was in the right of the two and stayed in the right of the two. They didn't change lanes at any point

The red car hit the blue car from the damage pattern.

The blue car may have been in the wrong place and not had the ROW, but that doesn't completely excuse the red car from hitting it, in the same way if a pedestrian jumps into the road in front of you when you have the ROW, you don't automatically have the right to mow them down. All parties have a responsibility to act safely and to attempt to avoid collisions at all times.

I would have said 50:50 on the insurance, with maybe a small probability that red could end up blameless if it could be shown that they had no chance of taking avoiding action (which would be difficult without evidence).

Shame that we will not find out, but the fact that both parties seem to accept the 50:50 seems like a smart decision to me. Hopefully not too expensive and a learning experience.

The red car did change lanes by crossing over the outside lane to get off the roundabout.

The Highway Code says:
When taking any intermediate exit, unless signs or markings indicate otherwise

• select the appropriate lane on approach to the roundabout
• you should not normally need to signal on approach
• stay in this lane until you need to alter course to exit the roundabout
• signal left after you have passed the exit before the one you want.

• pedestrians who may be crossing the approach and exit roads
• traffic crossing in front of you on the roundabout, especially vehicles intending to leave by the next exit

Therefore it seems that my earlier belief that red car was at fault is incorrect, as the HC warns the blue car to be on the lookout for cars passing in front.

As so many posters seem to know the roundabout concerned, could someone post the aerial image from Google?
It would be good to see all road markings and whether there are two lanes on the roundabout and the exit concerned.
It sounds as though blue caused the accident, by not knowing where they were going. However, red should not have assumed that cars on the outside lane were going to exit at the same exist as her, and checked if she was crossing another vehicles path. (Subject to seeing road markings).

Incorrect

Blue car totally at fault, hope you and baby are ok xx

Blue car fault. Give way to cars coming from the right on a roundabout.

Personally I think the blue car is 100% at fault. They shouldn't have entered the roundabout full stop as it wasn't clear. Obviously they REALLY shouldn't have entered the roundabout as there was someone in the lane they were travelling to

As there are clearly two lanes on that exit the blue car should assume that the two lanes on the roundabout correspond to those....as they do.
OP was in the right hand lane and exiting in the right hand lane.

The red car didn't change lanes. Stayed in the same lane that is marked to exit at that point.
The blue car changes lanes. If going straight on or right from the park they should drive across into the inner lane to continue round the round about.

Blue
Unless red indicated before passing the park/blue

Red car at fault. Both cars on the roundabout. Red car was changing lanes and was responsible for ensuring their way was clear.

Joining the blue car at fault brigade

Please ignore post above, have seen you have said you indicated left after the park. Blue firmly at fault. I don’t know why people are going on about lanes, you indicated correctly to come off, blue should
not be joining when there are cars coming round and should be giving way to the right. Blue should also have judged by your positioning that you were exiting and not carrying on round. Even if you were, they shouldn’t join on top of an incoming vehicle, they have cut you up. They clearly weren’t following the highway code as a PP keeps saying. I think you confused things by saying about blue indicating left, it suggests they were perhaps ahead of you in terms of you seeing it. People don’t seem to know how to use roundabouts. I get so annoyed with those who don’t bother to indicate or use the wrong lanes, mainly the left to go right.

If the red car is indicating left when they pull off then the blue car is not expecting them to go straight on. However, despite incorrect indicating (or the fact people don’t even bother) the blue car should have seen the positioning of the red and hesitated.
