This work describes Safe Wheel, an affordable embedded system developed to curb drunk driving incidents. It employs an MQ-3 alcohol sensor and an Arduino Uno to continuously assess the driver’s breath. Once detected alcohol surpasses a predetermined threshold, the system disables vehicle ignition through a motor cutoff mechanism. Instant visual and auditory warnings are issued via an LCD module and buzzer. Compact and economical by design, it can be enhanced later with GPS or GSM modules. Under laboratory testing, Safe Wheel successfully inhibited ignition in over 90% of simulated intoxicated driving scenarios.
