This project is designed by keeping in mind the accidental death caused on the roads because of the consumption of alcohol by the driver. The whole system can be employed in any steering wheel equipped motor vehicle. The system which is made as compact as possible senses the alcohol molecules present in a specific range and if found, fails the attempt of the driver to start the engine. Pushing the envelope and considering the actuality of the situation where the driver may not be able to drive, the system is interfaced with the widely used GSM technology to establish a quick cellular contact with the closest kin or with the law enforcers.
