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.

What this could mean

What this could lead to
If successful, this approach could help reduce car crashes and traffic violations among high-risk teen drivers.
What could go wrong
This is a completed Phase 3 trial, but results may not apply to all teens or regions. The device only works in cars made after 1996 and requires a smartphone.
