Texting and driving according to distraction.gov is most distracting because it involves manual, visual, and cognitive distraction simultaneously. According to the National Highway Traffic Safety Administration, distracted drivers are responsible for an estimated 25 to 30% of all vehicle collisions which amounts to 1.2 million crashes per year.
At any given moment during daylight hours, over 800,000 vehicles are being driven by someone who is using a hand-held cell phone. Drivers using hand held devices are 4 times more likely to get into crashes serious enough to injure themselves. They also are increasing their crash risk 23 times worse than driving while not being distracted.
Sending or receiving a text takes a driver's eyes from the road for an average of 4.6 seconds. At 55mph it is the equivalent of driving the length of an entire football field, blind.
