Over the weekend in Delaware I noticed this peculiar arrangement at many signalized intersections along the mega-arterial DE-1. At certain intersections, there will be a standard yield sign (R1-2) at the intersection of a right turn lane (a shared busway / cycleway / right turn lane) and the cross street. These lanes are not channelized insofar as there is no curb separation between them. However, beyond the stop-line there is a small painted island. Does the MUTCD 2B-09.01.C option cover an island if the island is only made pavement markings? During a snow event, the island is no longer present. :)

I don't think a physical island makes a difference, but the presence of a stop line should.
Something like that at http://goo.gl/maps/5kDNk and catercorner at http://goo.gl/maps/9FqAe as well.
