One man was killed and one woman was critically injured in a motorcycle crash in Gilbert over the weekend. Gilbert Police Officials said that accident occurred at approximately 9 p.m. at the intersection of Power and Queen Creek. The male rider was pronounced dead at the scene while the woman was airlifted to Osborn Medical Center and listed in critical condition with a head injury. Sadly, neither rider was wearing a helmet at the time of the crash; Police believe that alcohol was a factor in the crash. Arizona Law mandates that riders under 18 must wear a helmet securely fastened while operating a motorcycle. Statistics released by the Motor Vehicle Division state that nearly twenty-eight percent (28%) of all fatal or incapacitating injuries involved riders and passengers not wearing helmets. Though helmet use may not be required by law over the age of 18 in Arizona, wearing a protective helmet is always a wise decision.
