I've posted this before. I should note that these guidelines from 2009 are a result of direct action by BOLT. And by that I mean a deliberate action to acquire helmet tickets then challenging that ticket in court, including lawsuits against the CHP. AND as a reminder we currently have a Federal Class Action lawsuit against CHP and Sacramento Sheriffs Department. The attached is the most current CHP guidelines that I have. BUT, CHP does not make law.
If you have any questions, you know where to find me.
