[Stumped]

This one could run and run as all drivers seem to approach any particular hazard differently. I believe that the best way of dealing with a roundabout is to treat it like the face of a clock, the approach road always being 6-o-clock. Any junction prior to 12-o-clock should be approached from the left or nearside lane, any junction beyond 12-0-clock, the right or offside lane. Always works for me.
