Following laws is really just a small part of cycling safety. It's the "street smarts" that you develop but which are not taught to you that keep you safe. Keep behind that car on your left as you approach an intersection so he can't give you a right hook. Stay on the left of your bike lane while there a cars parallel parked alongside. Don't go full gas when riding alongside a traffic jam because some bozo may decide to pull in front of you because she feels she deserves a short-cut today. Practice emergency stops so shifting your weight to the back becomes second-nature. Learn to safely look over your shoulder while riding. Things like that are what's really going to keep you safe. I wish places taught that to new riders.
