Risky Driving EventsPrimary· Six months/study period
Risky driving events are continuously monitored for teens (240) across all three groups using an in-vehicle device and smartphone app. The system automatically detects and records driving events, including hard braking (≤ -0.45 g-force) sudden acceleration (\> 0.35 g-force), speeding (\>10 miles over the posted speed limit), and speed \>75 mph. Event rates are calculated as the number of risky driving events per 1,000 miles driven.

Unsafe BehaviorsPrimary· Six months/study period
Unsafe driving behaviors among teens (N = 240) are continuously monitored across all three study groups using an in-vehicle device and a smartphone app. The system automatically records behaviors such as speeding, and seatbelt nonuse (for selected vehicle makes and model years only), as well as the distance traveled while these behaviors occur. Unsafe behavior rates are calculated as the number of miles involving an unsafe behavior per 1,000 miles driven. Survey data supplement these measures by capturing self-reported distracted driving and seatbelt use for vehicles that are not fully compati

Adverse events — posted to ClinicalTrials.gov
Time frame: 6 months.
Reporting threshold: 0%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
The purpose of this study is to test the effects of an in-vehicle driving feedback technology, with and without parent communication training, on risky driving events, unsafe driving behaviors, and subsequent traffic violations among teens who have recently received a moving traffic violation.
