Nearly one out of every four motor vehicle crashes involves cell phone use.* Sixty-two percent of drivers recognize that talking on a cell phone is not safe, yet more than two out of three drivers admit to talking on their cell phone in the past month.
Driving involves three main activities: visual (eyes on road); mechanical (hands on wheel); cognitive (mind on driving). The brain quickly switches between those tasks sequentially. As a result, the brain suffers from inattention blindness and can't process everything the eyes see.
When this happens, drivers look out the windshield, but do not see up to 50 percent of the driving environment. In fact, the brain is so overloaded that not all critical driving cues such as red lights, stop signs and pedestrians are delivered to the brain.
So... when you're on the road, stay off the phone.
