In brief
Cell phone use more distracting to drivers than chatting with passengers
When it comes to driving, not all conversations are alike. A study published in December 2008 by psychologists at the University of Utah found that drivers talking on cell phones made significantly more driving errors than those who talked in person to passengers.
The researchers paired 41 drivers with friends. Participants ranged in age from 18 to 49, but most were young (the average age was 20), with men and women about equally represented. During each of three experimental conditions, one member of the pair was randomly chosen to be the driver and the other was designated the partner. During each experiment, the driver operated a driving simulator that not only mimicked actual traffic conditions but also measured aspects of driving performance.
