A new study reveals that teen drivers in the US are spending more than one-fifth of their driving time distracted by their phones, with many glances lasting long enough to significantly raise the risk of a crash. Published in the journal Traffic Injury Prevention and released on Thursday, the research found that, on average, teens reported looking at their phones during 21.1% of every driving trip. More than a quarter of those distractions lasted two seconds or longer, which is an amount of time widely recognized as dangerous at highway speeds.
Most distractions tied to entertainment, not emergencies
The top reason teens said they reached for their phones behind the wheel was for entertainment, cited by 65% of respondents. Texting (40%) and navigation (30%) were also common. Researchers emphasized that these distractions weren’t typically urgent, but rather habitual or social.
Teens know the risks
The study includes survey responses from 1,126 teen drivers across all four US regions, along with in-depth interviews with a smaller group of high schoolers. Most participants recognized that distracted driving is unsafe and believed their parents and peers disapproved of the behavior.
But many teens also assumed that their friends were doing it anyway, pointing to a disconnect between personal values and perceived social norms.
Teens think they can resist distractions
Interestingly, most teens expressed confidence in their ability to resist distractions. That belief, researchers suggest, could make it harder to change behavior unless future safety campaigns specifically target these attitudes.
The study’s lead author, Dr. Rebecca Robbins of Boston’s Brigham and Women’s Hospital, said interventions should aim to shift social norms while also emphasizing practical steps, such as enabling “Do Not Disturb” mode and physically separating drivers from their devices.
“Distracted driving is a serious public health threat and particularly concerning among young drivers,” Robbins said. “Driving distracted doesn’t just put the driver at risk of injury or death, it puts everyone else on the road in danger of an accident.”
What this means for parents and educators
The researchers say their findings can help guide educators and parents in developing more persuasive messaging about the dangers of distracted driving. One of the recommendations is that adults need to counter teens’ beliefs that phone use while driving is productive or harmless.
While the study’s qualitative component was limited by a small and non-urban sample, the authors believe the 38-question survey they developed can be used more broadly to assess beliefs, behaviors and the effectiveness of future safety efforts.
