Use hand signals when you stop or turn. Never carry extra riders. Any way I wear my helmet is okay. Helmets must sit at a proper angle. They cannot be tilted over the forehead or rest solely on the back of the head.
Helmets are too heavy and expensive.
Bicyclists must drive on the right-hand side of the road with traffic flow. Bicyclists travel with traffic. Never ride on the left-hand side facing oncoming cars. It is okay to wear headphones while riding as long as I am wearing a helmet. Headphones should never be worn while riding.
