You would not know how to properly and respectfully share the roads with traffic unless you make a personal effort to learn the proper techniques and etiquette.
We found this video to be very simple, short, and effective. It doesn't cover everything you should know before you decide to ride with traffic, but what you will learn in this video and the tips on the Cyclists VIP program, could save you from getting hurt or killed.
