<p>A system and method are described to disable texting while driving a moving vehicle. The position and speed of a user's cell phone are compared with that of a registered master phone. If the position and speed track that of the master phone, it is assumed that the user is a passenger and not a driver, and texting is enabled for that user. Texting at speed is disabled for a master phone user who may be an ordinary citizen or may be a professional driver of a mass transit vehicle. The user of a master phone may utilize a different service provider than a passenger. Information parameter measurements such as cell phone position, velocity, and direction of travel are time stamped and then passed between service providers or alternately made available to other service providers by way of a central database.</p> |
