Road accidents often result in serious injuries and fatalities due to delayed emergency response. This paper presents an Automatic Vehicle Accident Detection and Alert System using Arduino, GPS, and GSM technology. The system employs an ADXL335 accelerometer to detect sudden impacts or abnormal vehicle motion. Upon detection of an accident, the Arduino microcontroller retrieves real-time location coordinates from the GPS module and transmits an alert SMS via the GSM module to predefined emergency contacts. An LCD display shows system status and location details, while a buzzer provides an immediate alert. The proposed system is cost-effective, reliable, and significantly reduces emergency response time, thereby increasing the chances of saving lives.
