abstract = {Driving under the influence of alcohol is a major cause of road accidents and fatalities. The Alcohol Detection and Monitoring System with Engine Locking is designed to prevent drunk driving by using an MQ-3 alcohol sensor to detect alcohol in the driver’s breath. If the alcohol level exceeds a preset limit, the ESP32 Uno microcontroller activates a buzzer, displays a warning on a 16×2 LCD, and locks the engine or door using a motor driver IC. At the same time, the GPS module tracks the vehicle location and the GSM module sends this information to a registered mobile number for monitoring. This system helps improve road safety, prevent accidents, and supports intelligent vehicle safety systems. The system is compact, cost-effective, and reliable.},
