unfortunately what he said - why did you start moving right into offside lane as you left roundabout (to overtake polo ? - but you were quite a way back)from an insurance point of view this is going to be you at fault, with a potential of split (with you taking lion's share of liability). There are two lanes one the roundabout, yes I am aware the lines stop, however this is because BOTH roundabout lanes can come off at that exit. The left lane will NEVER cut across a lane that is coming off.
- if impact point is on the side of your car that would unfortunately show he was already occupying lane as you moved ?
