The significant number of automobiles running on the roads may increase traffic accidents globally. Drunk driving is a leading cause of traffic accidents worldwide. One of the project's key goals is to develop a method that may help to determine the amount of alcohol consumed by the vehicle's driver. A rise in the incidences has been known for a long time that people who drink much alcohol have high blood pressure may lead to accidents. Several recent investigations show that sample data from different countries have a link between alcohol consumption and blood pressure readings which may cause a Heart attack or paralyze the body. The system is intended to prevent the user from driving a vehicle when they are drunk. Drunk and Drive is a severe offense worldwide and needs to take strict action on people to reduce the frequency of accidents. The most important part of the proposed system is Arduino Uno, and an alcohol detection sensor (MQ-3). The study shows that most of the samples examined were positive, and blood pressure levels increased somewhat but a more predominant rise in those who consumed three glasses of wine or more daily. Blood pressure rises were recorded in 25% of studies in lower levels of intake, while roughly 40% in higher levels of consumption. Using SnO2 (Tin Dioxide)-PDDAC (Poly-Diallyl-Dimethyl-Ammonium Chloride) as the sensitive film, we have shown how to create an ethanol sensor that operates at ambient temperature, which is inexpensive and adaptable. We found that PDDAC not only acted as the binder but also helped to boost the sensor's functionality. SnO2- PDDAC's upper limit of detection at room temperature is 10 ppm and has an excellent endurance of at least two months. The sensor shows high selectivity to ethanol as well. These advantageous gas sensing characteristics make the suggested system become a Potential contender for measuring ethanol at room temperature with the proposed SnO2-PDDAC sensor
