Did you know? "There is no federal law in the U.S. requiring bicycle helmets. The states and localities below began adopting laws in 1987, mostly limited to children under 18." (www.helmets.org
) See a list of helmet state safety laws at the following address: http://www.helmets.org/mandator.htm
Law or not, anyone who wants to be safer should wear a helmet when riding a bike.
Sticking reflective stickers on your helmet is an easy and cheap way to enhance your visibility and safety.
