Summary

This study tested a community bike safety program for 195 kids ages 9 to 12. Some kids took a 12-hour safety class, some took the class plus a parent training session, and others received no training. All bikes were equipped with GPS and video cameras to track real-world riding behavior, near crashes, and safety mistakes. The goal was to see if the program improves safety skills and reduces risky riding.
