Agreed Jeff. As I understand CA law, the "duty to act" for EMS workers applies... but only if one is identified as such. So, people with a star of life or FF helmet sticker technically "need" to act. Of course, if it's one's day off and they're NOT identified (by Joe Schmoe saying, "Hey, that's the EMT that took care of me in my accident), then it's perfectly ok to keep driving and give the "EMT salute."
