Another online guide about safety that you might want to check out is
http://bicyclesafe.com/ ("How to Not Get Hit by Cars", Michael Bluejay). Be advised that there are some "politics" and controversy between John Forester's website/info/book and this one. I lean more towards the advice in bicyclesafe.com because it is a more practical guide (e.g. assumes that cars are going to break the law) but there is plenty in EC that is, well, "effective" too -- neither one should be discounted as a means to promote safe riding.
