The study, published in the June 29 issue of Human Factors: The Journal of the Human Factors and Ergonomics Society, found that drivers talking on cell phones, either handheld or hands-free, are more likely to crash because they are distracted by conversation.matthew5656 wrote: Oh and I would like to see a report that explains the idea of cell phone use having more of an effect than drunk driving. It sounds like a hoax to me. Alcohol impairs the vision, depth of perception, reaction times, among other things. A cell phone impairs one arm.
Using a driving simulator under four different conditions: with no distractions, using a handheld cell phone, talking on a hands-free cell phone, and while intoxicated to the 0.08 percent blood-alcohol level, 40 participants followed a simulated pace car that braked intermittently.
Researchers found that the drivers on cell phones drove more slowly, braked more slowly and were more likely to crash. In fact, the three participants who collided into the pace car were chatting away. None of the drunken drivers crashed.
