The national highways are the lifeline of a nation and facilitate smooth conveyance of both people and goods door to door within the country. Highways not only need proper planning and designing during the preparation but also require safe and smooth movement of traffic. This paper attempts to conduct study of road accident data in India, to minimize the accidents, and to analyse the perception data to understand safety aspect. The Secondary data regression analysis is also conducted with the consideration of accident-data as a depended variable, and the cost of vehicle maintenance in rainfall, as an independent variables to recommend suggestions to improve highway safety measures. If highway maintenance is not proper and regular then it causes more accident by increasing numbers of pot holes and cracks, because water retention on road is for longer time damages pavement. Hence maintenance an safety also correlated on highways.
