Sorry for the late response. I believe that you are talking about road biking as opposed to gravel or mountain. I don't know much about road biking so I asked my brother, who is a certified road bicycle safety instructor, to send me some links. I'm busy this morning but I'll post them this afternoon.
The main thing to remember is that you are basically invisible to drivers. So, anything you can do to make yourself more visible is a plus. But always act assuming that car drivers don't see you when you ride.
