Where to Find Mandatory Helmet Laws

Our list of Helmet Laws

We keep a current list of mandatory helmet laws by state and local jurisdiction.

The National Traffic Safety Board

The NTSB has made an unprecedented study of bicycle injuries and countermeasures, announced in 2019. They recommend major improvements in almost all of the elements that make up the bicyclist environment, and also the passage of all-ages helmet laws. An early press release in November 2019 said the study would be available soon.

"Assisting local communities in educating decision makers on the importance of a youth bicycle helmet law." If you are lobbying for a law, the Ohio Chapter of the American Academy of Pediatrics has produced this unique guide.

Texts of Laws

Exemptions for some riders in some laws

We have a page on helmet law exemptions with some of the exemptions that have been written into laws. A helmet law with exemptions is more difficult to enforce, since with some of the exemptions police cannot determine whether or not a bare headed rider might be exempt.

Other Views - some even opposed to ours!

We have a page up of responses to points raised in the Internet "helmet wars". It includes links to a number of sites that oppose helmet laws.
