A number of fatal lives are lost in the Indian roads day by day due to number of accidents. The prime ones being rash driving, negligence in driving and drunk & drives. Here a prototype is designed to avoid drunk & drives by using an automated system. Here the engine is inhabited from starting and running once alcohol is detected in the breath of the driver which is higher than the prescribed level permissible by law. Also provisions have been given in the system to indicate the level of alcohol in the drivers breath. This may allow him to be aware of physical and mental preparedness of his own-self and may help himself in handling the situation. This system as a whole consist of a MQ3 sensor, arduino board, LEDs, bipolar junction transistor, DC sugar cube relay, IC LM35DM,A plug to B plug cable and Permanent Magnet Direct Current motor(PMDC) with which the performance of this automated system is enabled. By mandating the installation of this prototype in automobiles the accidents due to drunk & drives can be considerably prevented and can efficiently save the valuable human lives.
