http://www.azleg.gov/FormatDocument.asp?inDoc=/legtext/48leg/2r/bills/sb1464p.htm I have been working with Senator Ron Gould sponsored SB1464. It will be heard in the transportation committee, that He chairs, soon. Senator Ron GouldServing Arizona's 3rd District, I have been working with State Rep: Trich Grow, Andy Tobin, Transportation commity member Jerry Weiers. BTW for those who are don't know, Federal DOT and State DOT work together, not in conflict. Each state has permission to enact there own laws for local city travel as there state see's fit. Federal law will step in on interstate issues however. Talk to your local state rep or Senator and educate yourself.
