In the United States, as well as worldwide, there has been substantial growth in the use of mobile wireless telecommunication services (mobile telephones). The use of mobile telephones by the drivers of motor vehicles has been the subject of certain state and local restrictions that were written because of concerns for driver safety. At the present time, eighteen states and the District of Columbia have enacted legislation concerning the use of mobile telephones by drivers of motor vehicles. The existing state laws vary greatly and are summarised in this book. Fifty-three pieces of legislation have been introduced in 2004 in twenty-six states and the District of Columbia concerning the use of mobile telephones by drivers of motor vehicles. The current status of state legislation is summarised state by-state in this book. The book includes a bibliography of other books regarding this issue, as well.
