| Measure |
Education Only (Control)
The Cellcontrol DriveID device will run completely in the background with no observable changes to cellphone functions while driving. During Week Four, participants will be presented educational materials on the dangers of distracted driving.
Education Only: No active intervention, educational materials will be provided
|
Opt-in Blocking
Participants will have to initiate Cellcontrol DriveID device when entering the vehicle; the blocking settings will be pre-set to block all calls and text messages when the car is in motion.

|
Opt-out Blocking
Cellcontrol DriveID device will automatically turn on when the teen begins driving and will be pre-set to block all calls and text messages when the car is in motion.

|
Opt-out Blocking With Notification
Cellcontrol DriveID device will automatically turn on when the teen begins driving and will be pre-set to block all calls and text messages when the car is in motion. If a participant overrides the blocking function, an email will be sent to a parent/guardian.
