Abstract: A method and apparatus with software supplied wirelessly as a downloaded application for preventing texting on cellular telephones while driving. A cellular telephone moving faster than a predetermined speed (for example 15 MPH) automatically locks out the texting function. Dialing of full telephone numbers under these conditions can also be locked out. If the phone becomes stationary for a predetermined period (say 3 minutes), the lockout can be removed. A passenger can enter an override code to prevent the lockout. In some embodiments the override code can only be entered when the phone is moving faster than the predetermined speed and/or when several buttons are depressed simultaneously requiring operation with two hands.
