Regarding passenger movement, the number of registered passenger cars in Turkey had grown nearly fourfold between 1995 and 2016, with there being 11.3 million licensed passenger cars by 2016. This figure translated into a motorization rate of 142 cars per 1,000 inhabitants. Apart from an increase in car sales, Turkey had also recorded a significant growth in its own manufacturing industries. Production figures for passenger cars amounted to 1.03 million units in 2018. However, this growth in motorization also had an effect on the number of road traffic fatalities recorded, which climbed to 7,427 in 2017.
