Government agencies drop 85% helmet benefit claim

US federal agencies The National Highway Traffic Safety Administration (NHTSA) and the Centers for Disease Control (CDC) have decided that they can no longer justify citing the claim that bicycle helmets reduce the risk of head injury by 85%. No subsequent research has ever found a benefit anywhere near as great.

The agencies had been challenged under the Data Quality Act to show why they still continued to cite the earlier estimate, which is often seized upon to exaggerate the potential benefits of helmets and to support helmet laws.
