Surely I'll earn 10 demerits with this question but how do I see on a bidirectional road what is forward, what is backward? Example: A road drawn in 2 pieces. When I put a stop sign on one part, the 'beam' points to the left, when putting a stop sign on the second part, the 'beam' points right. Practically each time I have to test a road section what is forward and what's backward, in the silliest example the road goes to Elice, destination:forward=Elice. On the next crossing the destination, following the beam lead, it becomes destination:backward=Elice although we're still travelling west. The wiki says something inconclusive to me literally 'how it was drawn'. What's the visual cue I'm missing?
