Teen-Parent Monitoring Group
Cellcontrol DriveID device will automatically turn on when the teen or parent begins driving and will be pre-set to block all calls and text messages when the car is in motion but participants will have the ability to override the blocking. The teen-parent monitoring group involves will send email notifications to the teen when their parent unlocks their phone while driving and vice versa.
Participants (parents and teens) will self-report information on their individual driving behaviors for the three weeks prior to study enrollment, including how often they report texting while driving and self-report cellphone use. At the end of the study participants will be asked to report feedback about the use the cellphone blocking technology and their perceptions for whether their safety improved using the technology.

Teen Only Monitoring Group
Cellcontrol DriveID device will automatically turn on when the teen or parent begins driving and will be pre-set to block all calls and text messages when the car is in motion but participants will have the ability to override the blocking. The teen only group involves parental monitoring of the teen's cellphone use while driving only. The parent will receive an email notification when their teen unlocks their phone while driving. Both parents and teens will drive under the same restrictions, but only the parent is notified of teen cellphone use.
Participants (parents and teens) will self-report information on their individual driving behaviors for the three weeks prior to study enrollment, including how often they report texting while driving and self-report cellphone use. At the end of the study participants will be asked to report feedback about the use the cellphone blocking technology and their perceptions for whether their safety improved using the technology.
