some research shows that hands-free calls are just as distracting as calls made on a handheld phone.
"The evidence is mounting that the conversation itself is the risk, not holding the phone", says Russ Rader of the Insurance Institute for Highway Safety. "The research shows the risk of having an accident is about four times higher for drivers using cell phones, whether it?s handheld or hands-free."
I think we?ve all see someone weaving in their lane while on a cell phone. That?s because a driver is not paying full attention to the road.
"Some degree of awareness changes when you?re talking on the phone and driving, and I think we all know this", says Marcel Just, a researcher at Carnegie Mellon University. "Just listening to someone talk on the phone while you are driving is going to reduce the quality of your driving performance", he says.
Distraction equals danger University of Utah psychology professor David Strayer has studied driver distraction for years. He says talking on the phone causes what?s called "inattention blindness". The driver looks but does not always see things that are there, such as pedestrians, stop signs, traffic signals, or other vehicles.
