But, there is also evidence that there are safety risks. Unlike seat belts, there is little data on the effects of a helmeted body in motion from a bike crash.
Officials often state that helmet laws reduce accidents.
A helmet cannot stop an accident. Instead of confusing the public with gross accident statistics that have no relation to the ability of a helmet to provide enough safety to even think about a mandate, many Officials don't quote, or even know, whether helmets have had an effect on the ratio of the number of deaths from head injury as related to the number of accidents. Follow the money trail. The insurance industry can't control their car drivers from hitting us, but they can control the number of targets their drivers can hit by backing helmet laws that reduce riding. This all dovetails nicely with the prejudice and propoganda against motorcycling.
