US Government Withdraws Claim That Bike Helmets Are 85 Percent Effective

米国連邦政府が自転車のヘルメットの効果は「85%」を撤廃

Courtesy of the Washington Area Bicyclist Association comes this report on the efficacy of helmets.

The 85% has been the governments lodestar, a long-standing claim that helmets prevent that percentage of head injuries.

It is based on a 1989 study from Seattle.

However, many later studies have been unable to replicate that data.

However, the media continue to repeat the figure.

We will continue to wear the helmet in crowded bicycle-lane free Kyoto, but the article gives pause.
