Hey! Cool!
I just checked the statute and it does indeed say "upon demand". Formerly, it said "upon request". Now it says "upon demand" both mid-paragraph and at the end when it talks about being issued a citation.
No more fannying about as to whether the cop "requested" the CHP or "demanded" it.
Somehow I missed that change.
So what I've pondered since the change....if I pin it with my other notes from mom to my jackie, have I met the legal requirement to "display" it?
