In the Socalist Republic of California, where smoking is banned, plastic bags are being outlawed, manufacturers are driven out by laws involving chemical use, and molester teachers can't be fired, helmets are required by law. Lane splitting is legal though. Go figure.
The cry of the bikers prior to the helmet law was "Let those who ride, decide". I agree with that to a point. Nobody wants their Big Brother telling them how to live their lives. Right before the law passed, the famous actor crashed his bike without a helmet and now he talks to the tv. Thus ended the debate.
Mscmkr, there wasn't a helmet law in AZ for over 18 when I was there 30 years ago, but there use to be an eye protection law. Is that still in place? Does everyone adhere to that?
