Is traffic in the intersection safe? And, putting up traffic signs as approved by your local government.
Question: Will traffic signs make an intersection safer?
Generally, yes. Unless it had a traffic light and now you’re replacing it with signs. Of course, if there’s little traffic at that intersection anyway, it won’t make much actual difference where safety is concerned.
The newer USDOT codes, and I believe most “First World” nations as well, though, require the “diamond grade” reflective materials to be the basis for most intersection signs, so it’s almost like having a traffic light anyway.
