Australia - National Route 1, National Highway 94, and New South Wales state route 55
Rivervale, New South Wales.
In all of the three+ months that I spent in Australia between 1988 and 1997, this was the only shield assembly that I ever found (although there were others at this corner). I’m not saying that there weren’t others, but they are exceedingly rare.
