Increased reliance on cellphones has led to a rise in the number of people who use the devices while driving. There are two dangers associated with driving and cellphone use, including text messaging. First, drivers must take their eyes off the road while dialing. Second, people can become so absorbed in their conversations that their ability to concentrate on the act of driving is severely impaired, jeopardizing the safety of vehicle occupants and pedestrians. Since the first law was passed in New York in 2001 banning hand-held cellphone use while driving, there has been debate as to the exact nature and degree of hazard. The latest research shows that while using a cellphone when driving may not be the most dangerous distraction, because it is so prevalent it is by far the most common cause of this type of crash and near crash.
