University of Utah Researcher David Strayer

Think you can drive and text or talk at the same time? Science shows your brain just can't keep up. University of Utah researcher David Strayer has been studying distracted drivers for 10 years. "The brain just doesn't work the way we'd like it to work," he says. "We can't multitask the way that a lot of people think they can."

David's research found that talking on a cell phone quadruples your risk of an accident. "For comparison purposes, someone who's drunk at a 0.08 blood alcohol level has a four-time crash increase. So talking on a cell phone is about the same as driving drunk," he says. "When you're text messaging, the crash risk goes up to eight times."
