New online training helps parents turn teen drivers into hazard-spotting pros

Summary
This study tested a web-based training program called HazAPP that teaches parents how to coach their teen drivers to identify road hazards. One hundred parent-teen pairs took part; half received the training and half did not. Researchers compared how parents instructed their teens during real drives and in a driving simulator, and measured the teens' driving performance. The goal was to see if the program improves the quality of parental instruction and teen hazard anticipation.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Hazard Anticipation Program for Parents of Teen Drivers (HazAPP) - a web-based behavioral training for parents
- What this could lead to
- If successful, this program could give parents a simple, effective way to teach their teens to avoid crashes, potentially reducing accidents among new drivers.
- What could go wrong
- This is a small, completed study (100 participants) that measured teaching quality and simulator performance, not real-world crash rates. The results may not apply to all families or guarantee fewer accidents.
