I. Introduction
DRIVER safety has always been an area of interest to research since driver distractions account for numerous accidents on highways. In multiple studies performed by the National Highway Traffic Safety Administration (NHTSA), it was reported that over 20% of the accidents are due to driver distractions. Further analysis showed that approximately 60% of these accidents were caused by drivers who were either talking on the phone, adjusting GPS devices or tampering with the CD player [1], [2], [3]. The high fatality rate has prompted industry and academic institutes to focus on embedding smart systems in the automobile that can aid a driver during a commute.
