Seems like a law that would make driving with a GPS more dangerous for many people. When I use a GPS (either dedicated, or my phone), I place it in a pocket in my center console, down below my radio / AC controls. This prevents me from constantly looking at it, as I rely solely on it's TTS feature. I consider this to be much safer, though it sounds like in California it would be forbidden.
Maybe it's not the law the woman violated. Naturally, she posted a blurry picture that makes it hard to read, on top of which google plus has decided I shouldn't be able to zoom in, so I can't quite make out the citation number.
