Brief summary

The purpose of this study is to conduct a randomized controlled trial to determine the effects of a cellphone app and a driving mode intervention on driving behavior in drivers aged 18-24 years.

Detailed description

For this study, 1200 teens aged 18-24 years will be randomized into one of three study groups for 6 months. Researchers aim to evaluate the effectiveness of commercial cellphone-blocking apps and driving mode interventions on cellphone use while driving and evaluate the effectiveness of commercial cellphone-blocking apps and driving mode interventions on high-risk driving events.

Interventions

BEHAVIORALCommercial Cellphone-Blocking App (Active)

The Fleetsafer app, which is a commercial cellphone app that uses a cellphone's standard sensors and function to block handheld cellphone use while driving, will be downloaded on the participant's smartphone.

BEHAVIORALDriving Mode

Apple's "Do Not Disturb" driving mode provided by Apple for iPhones or Google Do Not Disturb, Verizon Messages +, Android Auto or have another app, called LifeSaver installed on their Android phone (collectively referred to as driving modes; the specific driving mode for participants in this arm will be determined based on smartphone type and service provider).

Design outcomes

Primary

MeasureTime frameDescription
Calling, texting, and handheld cell phone use while driving5-month intervention periodNumber of calling occurrences, texting occurrences, and handheld phone use occurrences, per 1,000 miles driven. Higher numbers signify more calling, texting, and handheld cell phone use.
High-risk driving events5-month intervention periodTotal number of high-risk driving events (e.g., hard-braking, sudden acceleration, swerving) per 1,000 miles driven. Higher numbers signify more high-risk driving events.
