The goal of our study article is to improve driver safety and prevent accidents caused by drunk driving. This proposal proposes detecting the driver's BAC level and locking vehicle's engine if the BAC concentration exceeds the threshold. The alcohol sensor detects the BAC inside the driver's exhaled breath and transmits signals to the Arduino(microcontroller) to turn off the engine as well as to GSM. The Global System for Mobile communication (GSM) sends a signal to a pre-registered cellphone number indicating that now the driver is intoxicated, and the buzzer begins to sound, followed by the engine being locked. The engine will only start if the amount of alcohol detected is below the threshold set.
