When joining a two lane roundabout in the uk should I give way to traffic in both lanes or just the one I’m joining?

Question

I was in the inside of the roundabout turning right. There was a road joining about 20ft from my exit I signalled left to turn off when another car joined from that road and started honking at me.

Answer 1

Any vehicle already on the roundabout has right off way over vehicles entering the roundabout. You have to make a judgement as to whether you can join the roundabout without blocking any vehicle already on it.

Answer 2

I have to be in the right lane before merging into the left to turn off the island though.

Answer 3

I slow down and stop in front of them, then stare at them. If the honking doesn't stop I get out and go over to them for a 'chat'!

Answer 4

on any roundabout regardless of how many lanes you always give way to traffic on your right ...you should NOT have been on the inside if you were turning right
