Today in California the company behind Bell and Giro bicycle helmets won a lawsuit in which the plaintiff claimed his injuries from a 2010 crash were due in part to a design flaw. Attorneys for Easton-Bell Sports argued successfully that the injured man was not wearing his helmet properly at the time of his accident. Specifically, they argued that the helmet was worn too high, as seen here in the lower left picture:
I see children and adults wearing bike helmets in that manner all the time. They might as well not even wear a helmet. Get it right, folks: straight and level, and tight enough that it stays in place. You don’t want a loose-fitting helmet that shifts in a crash or obscures your vision by sliding forward. If you don’t know how to adjust your helmet—or your child’s helmet—I promise that any local bike shop will be happy to help you.
