Abstract: Now-a-days, accidents due to drowsiness condition are one of the major problems on highway. These types of accidents occurred due to drowsy and driver cannot able to control the vehicle, when he/she wakes. Accidents due to drowsy is prevented and controlled when the vehicle is out of control. Also the drunken drive also prevented with the help of alcohol detector in the vehicle. Here we are using accelerometer sensor for recognizing the driver is in the drowsiness condition. The drowsiness is identified by the accelerometer sensor by measuring the angle of tilt of the driver’s head. The accelerometer sensor is worn by the driver by means of the spectacles frames or cap. The alcohol consumption is also verified during the starting process of vehicle using alcohol detector. If the driver is drunk then the buzzer indicates and the vehicle doesn’t allow the driver to start the vehicle. If the driver is in drowsiness condition then the system will give alarm signal and the speed of the vehicle is reduced. The ultrasonic sensor will sense the obstacle to avoid collision with that and vehicle will be parked with indications. Also the message is displayed on LCD display in the vehicle to aware the passengers that the driver is drowsy through GSM.
