Way to Safety Cellphone Blocking

Way to Safety: Cellphone Blocking Technology to Reduce Cellphone Use While Driving Among Teens

Research participants will be recruited to take part in a randomized control trial. Participants' cellphone use will be observed during an initial baseline period. Participants will then be randomly assigned to one of four conditions: education only (control), opt-in blocking, opt-out blocking, and opt-out blocking with parental notification.

Detailed Description

Motor vehicle crashes are the leading cause of death in teens in the United State and for drivers aged 15-19 involved in fatal crashes, 21% of distracted drivers were distracted by the use of cellphones. Nearly 90% of teens expect a response to a text message within 5 minutes, and the compulsion to respond is stronger for messages from close social contacts. This suggests that behavioral-economic interventions such as immediate and frequent incentives are needed to offset the disutility caused by not being able to communicate by cellphone while driving. If proven to be effective, incentives could be scaled up via auto insurance discount contributions, school programs, and parental contributions.

Design Details

  • Primary Purpose: Diagnostic
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Placebo Comparator: 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.
Other: Education Only
No active intervention, educational materials will be provided
Other Names:
  • Control
Experimental: 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.
Device: Cellcontrol DriveID
Technology that blocks incoming and outgoing calls and texts.
Other Names:
  • DriveID
Experimental: 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.
Device: Cellcontrol DriveID
Technology that blocks incoming and outgoing calls and texts.
Other Names:
  • DriveID
Experimental: 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.
Device: Cellcontrol DriveID
Technology that blocks incoming and outgoing calls and texts.
Other Names:
  • DriveID
