The use of mobile phones while driving is one the most dangerous and widely seen causes of fatal accidents .The main aim of our project is to develop a system to keep a track on the person driving the vehicle and ensuring he does not evade from stringent laws enforced by the government and put his or passengers travelling with him in danger. This novel and easy technique facilitates the owner of the vehicle to control ignition until and unless the driver is ready to drive with safety (eg. driver is not under influence of alcohol, whether he is using seat belt, has he held the steering, authenticated himself etc) To meet the requirements of an vehicle diagnostic and track tool system this architecture integrates Global Position System (GPS), Bluetooth and a Microcontroller. The system can be used to monitor performance of the vehicle and tracking by communicating the obtained data via Bluetooth to a mobile phone and also storing it in an database. Diagnostic details can be obtained from an on board diagnostic system (OBD). The Bluetooth gives quick updates to the owner of the vehicle and data stored in the database can be accessed whenever owner wants either to check for vehicles performance , drivers performance or any other details.
