[Talk-us] No right turn on red

[Alan Mintz]

California being one of those more permissive states, I agree with the 
annoyance at those who don't know it's legal to turn right on red (or the 
other cases) unless specifically prohibited.

Because it is rare to see this prohibition, I believe it is important to 
tag and render it on the map, for the purpose of alerting the consumer to it.
