Alcohol-impaired driving is a major cause of road accidents worldwide. Traditional methods of detecting alcohol involve stopping vehicles and manually checking the driver's breath for alcohol content. However, these methods are cumbersome and not very effective in preventing accidents in real-time. This research aims to create an automatic alcohol detection system that would help increase safety on roads using an Arduino board and an LCD screen. The stated system entails MQ3 alcohol sensor incorporation together with Arduino Uno microcontroller, which specifically uses ATmega328 due to its more advanced features as opposed to other standard microcontrollers. The MQ3 sensor has sensitivity within 2 meters and can detect alcohol particles so it is suitable for any vehicle. Upon detection of alcohol, this system will automatically lock the motor preventing the driver from starting it. With such simplicity comes great success because this new way of doing things provides an efficient means for finding solutions in finding drunk drivers while keeping cars still safe on highways across the nation.
