Original language? I wonder what it means exactly, because it doesn't sound natural. These are bits of instructions and this may well combine with something else, but I confess to being a bit perplexed. I also notice that we have what appear to be regional alternatives (roundabout / traffic circle) so maybe this is simply sth I don't get because my English is GB acquired - although I had thought I was reasonably fluent in US!!
