Systems and methods for improving safety of a multi-function portable personal communications device can include determining a first position of the personal communications device, after a predetermined time interval, determining a second position of the personal communications device, determining the distance between the first position and the second position, determining the time interval in which the personal communications device moved from the first position and the second position, calculating an average velocity of the personal communications device based on the first position, the second position and the time interval and, if the average velocity of the personal communication device exceeds a predetermined value, sending an alert or inhibiting a function of the personal communications device. Other systems and methods that improve safety are also disclosed.
