Abstract: Millions of people worldwide do it. Many say “What’s the harm, they got home safely and no one was hurt?” Just because they made it home safely that does not mean that they're making a right decision. When putting those keys in the ignition and driving away after drinking people are not only putting their life at risk but they are risking the lives of all those they come across while driving. In this paper we are presenting the solution to avoid drink and drive situation by using the embedded system for early detection smoke and alcohol in driver’s breath, and providing mechanism to report the driving under the intoxication.
