Summary

This study tested whether an in-vehicle device that gives real-time feedback on driving, plus optional parent communication training, can reduce risky driving and traffic violations among teens who recently got a moving violation. 240 teens aged 16-17 with a valid Ohio license and access to a compatible car and smartphone took part. The device tracked hard braking, speeding, and other unsafe behaviors.
