Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This randomized controlled trial will evaluate an intervention that provides parents with objective feedback about their teen's driving as well as strategies to improve communication with their teen about driving. We will recruit 180 newly-licensed teen drivers and a parent or guardian. Our main hypotheses are that: parent-teen dyads who receive feedback will have reduced driving errors and increased safety behaviors than dyads with no feedback; and, parent-teen dyads who receive instruction on communication techniques will have improved quality and quantity of communication about driving than dyads not learning these techniques.
