According to data from World Health Organization, more than one million people died every year because of accidents that related to transportation. Meanwhile, according to data from KORLANTAS POLRI Indonesia, in 2018 there is 28.772 traffic accident. In order to prevent loss of lives in traffic accident, improve the safety standard of vehicle manufacturing, and to help investigate the cause of an accident. Vehicle Data Recorder (VDR) is designed and implemented in this research. The VDR is completed with engine monitoring system on demand. The system calculates the location from GPS, parsing data from OBD and then send it to server. The data transmission using GSM module worked well at outdoor with accuracy more than 70%. Meanwhile in-vehicle the accuracy of data transmission is more than 50%.
