Wear your helmet every time you ride, but please wear it right, too. The helmet should sit square on your head with the brow low and just above your eyes. Adjust the straps so they hold the helmet in place. If you can’t seem to adjust the helmet correctly, reread the owner’s manual, or ask friends, or visit a shop and ask for expert help. A helmet worn wrong will not protect you in a crash. Keep in mind, too, that helmets wear with age. You should get a new one at least every five years. And any helmet that’s been crashed should be replaced (they’re designed for only one impact).
