While riding in France recently, we had a couple of slight altercations with residents pulling out of a right hand junction and not stopping, so I thought I would find out a bit more about this unusual rule.
This sign means that there is NO priority from the right
This sign means end of NO priority so beware of vehicles pulling out from the right
I have found a very good site which explains about this these signs and also about the white post with the red stripes, not denoting a junction but right of way. Please check it out before you venture into France
