The only helmet safety video we have ever seen that is fun to watch. It was done by three Manitoba organizations and features fast cuttings, quirky humor, and good information in three minutes. You can access it on the Province of Manitoba website.
There is also a study guide to help get a classroom discussion going. This one is specifically limited to non-profit use by schools and community groups. Note: If the video stops in Windows Media Player at the opening menu screen, just hit enter to play it.
