Car crash on roundabout - who’s at fault?

169 replies

WeGoAgainIVF · 13/11/2025 10:32

Hi, I’m wondering if anyone would mind letting me know what they think about this situation and who’s at fault.
I had a car accident last week and I’m stressing out waiting for the insurance companies to settle the claim. I know this can go on for weeks so I would be grateful for any input as to how it might go!
To be unbiased I’m not going to say which car I was driving.

Car X enters roundabout in right hand lane to go straight on (on this particular roundabout you are able to go straight on in both lanes).

The traffic in the left hand lane was queuing to get on the roundabout but had left a space for traffic approaching the roundabout from the left to enter.

Car Y entered the roundabout between the cars in the left hand lane, while Car X was already in the right hand lane, speed unknown but at a guess 30mph, maybe a bit more. Car Y collided with Car X.

Car X didn’t know exactly how fast they were going. Car Y said they had been on a long journey, it was dark and Car X was black.

Who is at fault?

Y. Whoever wasn’t coming from the right will be in the wrong. Obviously drivers should be aware, particularly where a gap has been left, but if I was taking advantage of that gap, I would be looking very carefully to my right to make sure traffic on the r/about with right of way wasn’t coming towards me.

Yes I'm pretty sure it's that simple, I wouldn't stress about it. You were already on the roundabout, they drove into you. It being dark and the colour of your car are irrelevant

I really don’t think it is because there’s 2 lanes. If X was going at 30 then Y was almost certainly there first but was having to nose through traffic where as X came later but with wild speed because 1 lane was clear.

EeyoresLostTail · 13/11/2025 19:13

I would think its Car Y that is at fault as Car X had already entered Roundabout and surely if they had done a long journey maybe their Concentration was slipping saying it was a Black Car at night is no excuse

Just out of curiosity OP Are you X or Y?

On a simple one lane r/a, that applies. But this sounds bigger, has 2 lanes all the way round, and could be large enough for Y to enter the r/a, become fully established in the left hand lane with the intent to proceed straight across (like the OP) and find themselves in a collision because another car cuts across their lane to exit.

We need a diagram or accident location to work it out. 🤓

Literally here expecting, and hoping for, a diagram

If the OP gives us the location of the r/a, where she entered & was intending to exit, and where the other car came from, we can all go off & check out Google maps to see if that helps. 🤞

A vehicle already on the roundabout has priority over any joining traffic. That's it.

KarmenPQZ · 13/11/2025 18:55

No it’s the front but on the passengers side because she’s swung out wide to turn.

x was really unsafe driving so fast. Especially if it was indeed dark and Y had their lights on. X would have had to see those lights really clearly

Not if car X was already nearly past where car y was entering. It sounds to me like they clipped the back of car X whilst entering at speed!

I've done a rudimentary drawing of my understanding which will hopefully load up

But that's car Y drivers side not passenger surely

I can't picture the scene from your description. Can you add a diagram please?

Autumvibes · 13/11/2025 18:38

Car Y. However car X should have been approaching carefully knowing the left side of them was queued.

Trixie62 · 13/11/2025 18:34

Car y at fault as should give way to the right

firstofallimadelight · 13/11/2025 18:27

I agree car y but often insurance companies will settle on a percentage basis of blame (except a rear collision) I was once hit by a car leaving a junction who hadn’t seen me behind the car turning left in front of me. It was their fault as they shouldn’t have left the junction but the insurance companies went 60/40. (In my favour)

Crazydoglady1980 · 13/11/2025 18:26

WeGoAgainIVF · 13/11/2025 16:02

I wasn’t cutting into the left lane. I entered the roundabout in the right lane and stayed there, with the intention of exiting in the right lane. This particular roundabout you can exit in both lanes in the direction I was going

But you did because you have to cross the left lane to exit. I suspect the insurance company will end up stating 50/50.
When crossing any lane it is your responsibility to check that lane is clear, which it wasn’t. It is also the other car’s responsibility to check that it is clear to enter the roundabout

MrsBennetsPoorNervesAreBack · 13/11/2025 18:15

Well, yes, it is obvious, given that the OP confirmed this several hours ago!!

Oh right, OK.

I couldn’t be bothered to read more than the first page as it’s so obvious.

Madformaltesers · 13/11/2025 18:16

Y

MrsBennetsPoorNervesAreBack · 13/11/2025 18:15

IridiumSky · 13/11/2025 18:14

OP: You’re obviously car X 🙄

If the description is accurate, car Y is at fault.

Croakymccroakyvoice · 13/11/2025 18:15

Speed isn't relevant for liability but it's something for you to reflect on, that you could have been more prepared for the risk of this happening. In this case you were clearly proceeding in the correct lane and she drove into you so I'd say it should fall in your favour.

The entire thing could have been prevented if people would use both lanes and merge in turn though!

IridiumSky · 13/11/2025 18:14

If the description is accurate, car Y is at fault.

CastleCrasher · 13/11/2025 18:11

Ate you in the UK? I don't understand her passenger side (left of her car) hit your passenger side (left of your car) if she was in the left lane and you in the right lane. Even if she was moving into the right lane, she would have had to have AWFUL road positioning (to the point of either going the wrong way on the roundabout, or driving straight over it) to make this possible surely? @mumofbun Disgram does a great job of sorting that. Are you sure if the point of impact? (Either way, it sounds like she's at fault, I'm just confused on the physics!)

Jiski · 13/11/2025 18:09

Car y, but they usually do 50/50 at roundabouts

Loubelou71 · 13/11/2025 18:07

I always think roundabouts become a bit of a game with people going to fast as though to prevent other cars joining. I think you should have been going slower and anticipated better so both are at fault really.

FenceBooksCycle · 13/11/2025 18:06

Car Y entered the roundabout without giving way to the right. They bear the majority of the fault because it wasn't their right of way.

Car X may be assigned up to 25% of the blame purely because the speed you choose should always be appropriate so that you could stop if someone does something stupid in front of you, as far as possible. I would suggest that 30mph was too fast for this situation.

However the colour of the car and the length of the journey is utterly irrelevant and the driver of car Y was definitely driving without due care and attention. No one should be in control of a car if they are in a state of mind/capacity of visual clarity where they could cause a collision if they encounter a black car. There are loads of black cars.

mumofbun · 13/11/2025 18:02

MoveOnTheCards · 13/11/2025 17:04

But she would have to have been driving in the opposite direction to you (or as good as) for her passenger side to hit yours, especially if she was coming in from the left.

Not if car X was already nearly past where car y was entering. It sounds to me like they clipped the back of car X whilst entering at speed!

Car crash on roundabout - who’s at fault?
Willowkins · 13/11/2025 17:54

Car Y
I also had an accident on a roundabout (in my case the other car hit mine when the driver decided to change lanes)
I only mention this because it can be a long process. It took over 2 years before the other driver admitted liability. We even had a court date set although that didn't happen in the end.
My initial costs were paid straightaway and luckily I had No Claims protection and motor legal as part of my insurance but it still meant a very long wait before the increase in premiums and excess fee were settled.
