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.
For this study, 240 teen and parent/guardian dyads will be randomized into one of three study groups for six months. Teens will be aged 16-17 who committed a moving-related traffic violation and their parent/legal guardian who is most involved with their driving. Researchers will aim to determine the effects of the intervention on teens' risky driving events, unsafe driving behaviors, and traffic violation recidivism. Additionally, researchers will aim to determine the effects of the intervention on frequency and quality of parent-teen communications about safe driving practices.

| In-vehicle device | Combination Product | The Azūga™ in-vehicle driving feedback technology, which consists of a pager-sized device plugged into the vehicle's on-board diagnostic port (installed in the teen's car) and a smartphone app (downloaded on the teen's smartphone), will be installed/downloaded. Three types of feedback will be provided to intervention teens: 1) Direct audio feedback from the installed device; 2) Push notification on the phone screen when a trip ends, 3) Detailed cumulative driving data; and 4) A customized biweekly driving summary report. |
| Measure | Description | Time Frame |
|---|---|---|
| Risky Driving Events | 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. | Six months/study period |
| Unsafe Behaviors | 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 compatible with the in-vehicle device. | Six months/study period |
| Measure | Description | Time Frame |

| Recidivism | Recidivism is assessed by linking traffic citation and court disposition records to participants' driver's license numbers. Data collected include violation dates, types, and intervals between the index and subsequent violations. | Up to one year post-study period |

Parent-teen communication is assessed using REDCap surveys. Teens and parents rate the frequency (0-3) and success (1-10) of discussions about 26 driving skills and safety principles from the past month. Frequency scores range from 0-78, with higher scores indicating more frequent communication, and quality scores are weighted averages expressed as percentages (1-100%), with higher scores indicating higher quality communication. Additionally, one voice-recorded conversation per survey is also coded by trained raters for active listening, OARS (i.e.,open questions, affirmations, reflective listening, and summary reflections) use solicitation of the teen's perspective, focus on behaviors, and emotional expression, with each behavior scored 0-3 to generate a summary quality score, with higher scores indicating higher quality communication. |

Engagement with device feedback will be measured among teens in the Feedback Only Group and the Feedback and Parent Communication Group and parents in the Feedback and Parent Communication Group via online tracking of the participant's web interface using Google Analytics. |
