Abstract: The Smart Alcohol Detection and Automatic Engine Locking System aims to improve road safety by blocking intoxicated individuals from operating vehicles and reducing reckless driving behaviours. By combining an alcohol sensor that measures breath alcohol concentration with an accelerometer that detects sudden and erratic acceleration the system identifies reckless driving behaviour. The system engages a relay to lock the engine by disabling the vehicle's ignition when alcohol levels surpass a set threshold. The system responds to rash driving by reducing speed or shutting down the engine and sends immediate alerts through a GSM module to inform authorities or emergency contacts. The system includes GPS tracking to provide location information when alerts are activated. The LCD display shows real-time updates about the system status directly to the driver. An Arduino Uno microcontroller serves as the project component that manages sensor inputs and executes appropriate output actions with efficiency.
