A new study from Mass General Brigham researchers offers a stark reminder of how pervasive cell phone use while driving is among young people. The study team developed and disseminated a questionnaire to over 1,100 participants and conducted 20 interviews for high school students to identify the factors influencing them to engage in distracted driving. They found an average of 21% of teen drivers drive distracted and share other insights behind the behavior. Their results are published in Traffic Injury Prevention.
