The Smart Zone Vehicle Speed Limit Control System is designed to enhance road safety in critical areas such as school zones, hospitals, and residential neighborhoods. It uses RF communication and an ESP32 microcontroller to automatically detect smart zones and regulate vehicle speed. Upon entering these zones, the system reduces speed through motor control and alerts the driver via LCD displays and buzzer warnings, ensuring compliance with speed limits and preventing accidents
