Researchers have evaluated drivers' ability to focus their attention on both their cell phone calls and the driving environment. In general, the strong conclusion has been that
◦ drivers' attention is not significantly distracted from the driving environment by cell phone use.
◦ cell phone conversations divert drivers' attention from the environment in which they are driving.
◦ cell phone use while driving distracts drivers but does not have behavioral consequences.
◦ a full range of driving skills is maintained when drivers simultaneously talk on their cell phones.
