Since moving home, I regularly traverse a large roundabout on my daily travels. I have a question regarding lane etiquette on approach. The road leading to the roundabout from my approach is a dual carriageway. At the roundabout there are three lanes. For the purposes of my journey, I wish to go "straight ahead" which is technically the third exit, this requires the middle lane. However, the middle lane is positioned between both lanes of the dual carriageway, so on approach, who has right of way to enter the middle lane? Cars on the left or those on the right?
I ask, because quite often there appears to be much confusion from all involved. Some people slip into from the right, others from the left - both usually aggravated by the other.
Here is a link to a GoogleEarth image of the lane I'm talking about:
