Drink & drive is a leading cause of road accidents. Detecting drunk driving requires stopping vehicles and manually scanning drivers by using breath analyzers. Well here we propose a system that allows to detect drunk driving in the vehicle itself. Our system uses alcohol sensor with raspberry pi along with a GSM modem for sms notification and LCD display and also a motor to demonstrate as vehicle motor. Now our system constantly checks for driver alcohol content. The system first allows the user to configure admin numbers into the system. And if the system detects driver is drunk above permissible limit, the sensor inputs trigger the processor about the issue by providing respective voltage. Now the system sends sms notifications to both the registered users/authorities to inform about the issue. Also the system stops the motor to demonstrate as engine locking of the vehicle. Thus the system detects and prevents drunk driving incidents automatically.
