I found this article reporting on findings of their study on helmet laws and their impacts on road safety:

Insurance Institute for Highway Safety (October 20, 2024) Lax helmet laws have killed more than 20,000 motorcyclists, study shows, https://www.iihs.org/news/detail/lax-helmet-laws-have-killed-more-than-20-000-motorcyclists-study-shows [Last accessed: 10/23/2024]

To quote from the article:

“Wearing a helmet is one of the biggest things riders can do to protect themselves from death and traumatic brain injury,” said Eric Teoh, IIHS director of statistical services and the author of the paper. “We understand that requiring helmets for all riders everywhere would be unpopular with some motorcyclists, but this could save hundreds of lives each year. Those aren’t just numbers. They’re friends, parents and children.”

There’s a link to the study report in the article for those who want to have a copy of the report.
