Drivers on cell phones clog traffic

Motorists who talk on cell phones drive slower on the freeway, pass sluggish vehicles less often, and take longer to complete their trips, according to a University of Utah study. “At the end of the day, the average person’s commute is longer because of that person who is on the cell phone right in front of them,” says Dave Strayer, a University of Utah psychology professor and leader of the research team.
