First seen Jun 26, 2026 · Last updated Aug 11, 2026 · Updated 5 times

Summary

This study tests whether a short online hazard perception training can improve driving and reduce crashes among 8,000 teen drivers in Washington State. Participants are randomly assigned to receive the training or a placebo (vehicle maintenance videos). Researchers then track crashes, near-crashes, and hard braking events using in-car sensors. The goal is to see if this low-cost intervention can make roads safer.

Active substance
Hazard perception training (behavioral intervention)
What this could lead to
If it works, this could point toward a simple, low-cost way to reduce teen car crashes and save lives.
What could go wrong
This is a large but early-stage behavioral study. The training may not reduce crashes in real-world driving, and results may not apply to all teen drivers.
