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. Cyclists need to be aware of their surroundings, especially sounds of traffic. Good cyclists never scan the road behind them when riding.
