Transportation plays a very important role in the progress of society as demand for transportation increases in tandem with the development process. It is one of the major industrial sectors of an economy. Over the years, Bangladesh achieved considerable economic growth (GDP more than 7 percent and 8.13% in the last fiscal year) with a stable unemployment rate and a significant rise in foreign investments. As a result, the purchasing power of individuals has risen along with the demand for cars, motorbikes, and commercial vehicles. The demand ranges from luxury inter-district buses to small sedans. To meet these demands, Bangladesh has to depend on imported vehicles as they are not manufactured in Bangladesh.
