We propose to test a potential intervention to reduce distracted driving among high school students that could be used as part of future research trials and school campaigns. This intervention is designed to encourage use of a setting that silences incoming calls and messages while the person is driving.
The purpose of this study is to test an intervention to reduce distracted driving among high school students. We're interested in learning the use of Do Not Disturb While Driving (DNDWD) by high school students. Participants will be recruited to participate into a 4-week study. Those that consent will download a driving app that will monitor their phone use while driving. Halfway through the monitoring period, we will ask participants to turn on DNDWD. Participants will also have the opportunity to enroll into an auto-reply message contest for best message. Once the 4- week monitoring period is complete participants will complete and exit survey

| Seconds of active (handheld) phone use per hour of driving | This is a composite outcome that measures the proportion of total trip time in which the driver is engaged in handheld phone call use or non-call handheld use (e.g. texting, swiping, and typing), as measured by the Way to Drive app. Several studies (e.g. Klauer, NEJM, 2014) have demonstrated the association between handheld phone use (e.g., reaching for phone, typing, swiping, dialing) and increased crash risk. This outcome is also known as the active phone use percentage. Passive phone use (e.g. phone is streaming GPS navigation directions or music without any typing, swiping, and handheld holding of the phone) is not included in this outcome. Trips are only counted if the app predicts the user was a driver for the trip based on the phone sensor data and the user does not correct the app; or, if the user corrects the app and indicates they were driving. |

| Fast acceleration events per 100 miles. | Fast acceleration events are detected by the app. Acceptability of interventions will be measured using a mixed-methods approach: | For the duration of the study; 4 weeks |
| Net promoter score | In the exit survey, participants will be asked "How likely is it that you would recommend this program to a friend or colleague?" on a 0 to 10 scale. | For the duration of the study; 4 weeks |
| Responses to open-ended questions in exit survey | Participants will be asked the following two open-ended questions: 1) "Please tell us what you liked about participating in this study;" 2) "Please tell us what you didn't like about participating in this study and how we should improve the experience in the future." These qualitative responses will be coded for content related to intervention acceptability and emerging themes will be identified. | For the duration of the study; 4 weeks |
