Roundabout exits - third from left lane

[Blockbuster]

I was at this roundabout on a retail park, indicating right to take the third exit and this Citroen driver drew up alongside me in the left lane which he stayed in to take the same exit as me, causing me to have to hit the brakes (and horn).

We were going from the 12 o'clock exit to about the 8 o'clock exit (5 exits in total at approx 12, 3, 5, 8 and 10 o'clock).

It's possibly a poorly designed roundabout anyway as the lanes aren't marked, but I'm convinced that both me and the Nissan in front of me were in the correct lane, and the Citroen should only be using the left lane for either of the first two exits. Does anyone disagree?

Thanks for the replies. Posting this in the Advanced Driving section was probably incorrect, as I do not have any advanced driving qualification. I do have 24 years and 15 to 20k miles a year worth of experience but am not an advanced driver.

Why would you use the horn?

Because I am not an advanced driver. I admit that it was probably used to show anger more than anything else.

Need to show the roundabout sign to get a better understanding.

But regardless of if they have chosen the correct lane you are trying to change lane across someone else and exit in one go?

There are no signs. The roundabout is completely within the retail park and has no signs at any of the roundabout entrances. Although they have faded badly so don't show up on the video, Google street view shows there are actually arrows where I entered the roundabout - left lane is straight on and left turn, right lane is straight on and right turn.

This other car by positioning himself alongside me gave me no oppurtunity to change lanes at any time. As he wasn't indicating, one could reasonably assume that he was going to take the second exit, and I would change lanes after that.

If you are posting this in the Advanced Driver section, then we can assume you want to understand the 'advanced driver' approach - which is simple, make no assumptions about other drivers / vehicles on a roundabout...

This seems to be good advice. Don't trust anyone else seems to be the way to use a roundabout.

so, you shouldn't be 'hitting' the brakes - you should be constantly aware of what they are doing and adjusting for it - surely, their not turning off at the previous junction was a good clue?

I didn't hit the brakes as such, maybe just tapped them lightly. You are right, I should have noticed. I was kind of watching the car in front, assuming that the Citroen was going to the second exit, given his lack of indicators and it took me a moment to realise he was still in my path. In the video there was only about 2 seconds between him passing the second exit, and me going for the third exit.

watching the video - there is no left / right lane - there is one lane onto the roundabout

The marking are worn to the point of being almost non existent, and the lighting conditions don't help, but there are are 2 distinct lanes shown on Google Maps and as mentioned above, left is left turn and straight on (exits 1 and 2) and right lane is also straight on and right (a bit ambiguous what the straight on here means to be honest, but I would interpret the right turn would be exits 3 and 4)

akirk said:

why were you exiting from the inside lane - you should have been over in the outside lane / left roundabout lane after the first or at latest, second exit - i.e. where the hatching started...

Yes, possibly but this Citroen driver blocked me from doing this.

In my mind the Citroen driver is in the wrong and probably didn't want to wait behind you.

Thanks for agreeing. It seems that a lot of people don't

In general, I think its just a poorly signed and laid out roundabout and whilst I should have expected the unexpected, the Citroen driver at the very least should have indicated his intentions.

Is the next/last right turning a more significant one, e.g. the main in/out road?

There’s 2 roads in/out and they are off the third and fourth exits. I would say the third exit (the one we were all going for) is probably the more popular road for both leaving and entering the retail park.
