ABSTRACT-In this prototyped project, an attempt will be made to develop a locking system for cars so it would not start without an alcohol checking mechanism. The system will be the advantage of a pre-existing Alcohol sensor.In the united states of America alone and during 2014 nearly “9,957 people died of alcohol- impaired-driving” that is one alcohol-impaired-driving fatality every 52 minutes. alcohol detectors are not proposed in any of the vehicles, hence there is a chance for anyone to drink and drive. Traffic police uses alcohol detectors to avoid drunk and drive system. The list goes on and on for other countries too, therefore, it is necessary to enhance and improvise new techniques. This project pushes towards public safety in general and roads safety in particular. Alcohol Detector in Car project is designed for the safety of the people seating inside the car. Alcohol Detection with Vehicle Controlling project helps to control the accidents in case the driver has consumed the alcohol Keywords—Alcohol detection system; Vehicle control; MQ3 sensor; camera; advanced fingerprint sensor;
