It’s no surprise that talking on the phone while driving is distracting. But now researchers at the University of Warwick have quantified it. A mobile phone conversation impairs a driver’s visual attention so much that it can add more than 18 feet to the braking distance of a car traveling 60 MPH and cause 83% more errors in driving. What’s more, these findings apply even to drivers who are merely listening on the phone and using hands-free devices.
