Does the use of a cell phone while driving increase crash risk?
A recent study found that the risk of collision when using a cell phone was four times higher than the risk when a cell phone was not being used. Crash risk was higher both for units that allowed the hands to be free and hand-held units. Other studies have shown that drivers who use cell phones while driving have higher crash rates, even if the use of a cell phone is not implicated in the crash.
