Traffic accident increased periodically in alarming rate and it was a serious problem throughout the globe particularly in developing countries like Ethiopia. This research concerns on Analyzing Road Traffic Accident in Ethiopia from 2007/08-2017/18. The main objective of the study was to investigate the growth rate of road traffic accident, road network coverage and motorized vehicle, and relationship between them in the past elven (11) year. In order to address the required objective the study use secondary data collected from Ethiopia federal police commission, Ethiopia road authority and Ethiopia federal transport authority. Basically, descriptive and inferential statistical analysis approach was used to analyze the data. The finding of the study revealed that; in the past eleven year more than 291577 Road traffic accident, 912956km road network and 681000 motorized vehicles were developed. Due to Road traffic accident Ethiopia loses around 36.3 billion birr (estimated 1.3 billion $ in current exchange rate of 28 birr for 1$) in the past eleven (11) year in Ethiopia. In average annually Ethiopia loses around 0.9% of budget due to traffic accident in the past eleven year. Average annual growth rate of road traffic accident, road network development and motorized vehicle were 9.16%, 10.81% and 13.34% respectively. In Ethiopia in the past eleven (11) years more than 276491 road traffic accidents, 912956km road network and 681000 number of motorized vehicle were newly introduced since 2007/08 in the study period. The variation on road traffic accident, road network coverage in km and motorized vehicle between commencement of study period (2007/08) or Ethiopia millennium (2000E.C) with end of the study period (2017/18) were estimated around 25914, 82414 and 563003 respectively. Finally, the study intends that road traffic accident had no direct or indirect relation with growth of motorized vehicle and road network coverage in Ethiopia. To curb the problem faced due to road traffic accident the government and other stakeholder must careful the issues to minimize road traffic accidents in Ethiopia.
