Wearing a helmet is the single most effective way of reducing head injuries and fatalities
resulting from motorcycle and bicycle crashes. Motorcyclists who do not wear
helmets are at a much higher risk of sustaining head injuries and from dying from
these injuries. In addition, riders who do not wear helmets place additional costs on
hospitals (see boxed example below), while the disability that results from these head
injuries incurs costs at an individual, family (or carer) and societal level.
