I'm not talking about highways but country roads. The signs cancelling give way to the right are used in many urban and rural locations. But the absence of them doesn't always mean give way to the right -- you might be able to see they have a stop sign, or the smudge of a line indicating a stop sign you can't see. It's incredibly bad design.
Well, the signs described in the article are only used on the highways, so if they were talking about non-highway driving I guess they may have missed that detail heh
Sounds like they're talking about the fact that at an intersection, unless signaled otherwise, the people coming from the right have right of way.
