Accident is today’s major problem. People driving vehicle carelessly,so accidents are increasing. Drowsiness while driving is one of the main causes of accident, especially one way routes such as highways. According to the National Highway Traffic Safety Administration of the United States of America (USA), starting from 2005,there is an estimated 1,00,000 police reported crashes per year, caused by driver drowsiness.The aim of our project is to develop a model for sleepiness detection system .The focus are placed on planning a system can accurately monitor the open or closed state of the driver’s eyes and alcohol detection system will truly prevent a car from starting if driver is intoxicated. In proposed system we are detecting driver drowsiness by using camera and also detecting alcohol by using breathalyzer mechanism and ignition inter-lock device in image processing. This system also detect driver yawing while driving vehicle. So, as the rate of accidents is increasing day by day, it helps to reduce the ratio of accident because of drowsiness and alcohol detection as well.
