Interventions

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.

Parent Communicationbehavioral

An individualized virtual training in communication strategies about driving safety along with a booster session will be delivered by a traffic safety communication specialist to subjects in the Feedback and Parent Communication Group. Intervention parents in this group will also be provided with access to an online parent-teen safe driving communication guide, including includes three motivational interviewing technique demonstration videos and 26 safe driving lessons.
