Way to Safety Cellphone Blocking

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.

About this study

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.
