The evidence on hands-free cell phone devices while driving
Whether itââ¬â¢s a quick call to ask whatââ¬â¢s needed from the grocery store or catching up with a long-distance friend " people everywhere talk on cell phones while theyââ¬â¢re driving.
Itââ¬â¢s long been recognised that talking on the phone while driving increases your risk of being involved in a crash. But in recent years, car and technology companies have marketed hands-free devices as a safer way to talk while driving.
Now a growing body of evidence suggests using hands-free phone devices such as ear pieces and Bluetooth is equally as dangerous as talking on a cell phone normally.
The latest study, commissioned by the American Automobile Association and performed by researchers are the University of Utah, measured the cognitive distraction created by performing a wide variety of tasks while driving. Listening to the radio or a book on tape proved to be the least distracting activities, while performing a verbal cognitive task involving math and word recall proved to be the most distracting. Talking on a hands-free cellular device ranked in the middle of the spectrum " more distracting than talking to a passenger and slightly less distracting than holding a phone up to your ear.
Thereââ¬â¢s more evidence, as well. A systematic review published in 2009 found talking on the phone " hands-free or not " has a negative influence upon driving performance. And it found that people talking on hands-free devices drive at faster speeds than those using hand-held device possibly because the hands-free device provides a false sense of security, resulting in a greater incidence of car accidents.
In addition, a 2012 white paper by the National Safety Council " which includes references from more than 30 research studies " found that ââ¬Åthe cognitive distraction from paying attention to conversation " from listening and responding to a disembodied voice " contributes to numerous driving impairmentsââ¬Â including inattention blindness (when drivers look at, but do not ââ¬Åseeââ¬Â objects in their path), slower reaction times and problems staying in a lane. That paper concludes: ââ¬ÅDriving while talking on cell phones " handheld and hands-free " increases risk of injury and property damage crashes fourfold.ââ¬Â
Taken together, the evidence is clear: Talking on the phone while driving " even when using a hand-free device " is not safe. So they next time youââ¬â¢re tempted to make that quick call or pick up the phone while youââ¬â¢re on the road, take a moment to think about what the research shows.
