Sorry, *16 additional states. The total is 19 (including DC). 29 have some age restrictions, where people under a certain age must wear helmets while riding, and only 3 have no laws requiring riders to wear helmets. I think Puerto Rico has a pretty strict helmet wearing law since 2007[1]. I haven’t found any data about the other territories. 1: https://www.nhtsa.gov/sites/nhtsa.gov/files/documents/812397_puertoricomclaw.pdf https://www.nhtsa.gov/sites/nhtsa.gov/files/documents/812397...
