A constant change in lifestyles and occupations, rural to urban migrations, increasing populations, urbanization and modernizing infrastructures has made man more and more dependent on vehicles. Vehicles are a means of transportation for all. In the pursuit for a better economy the developing world has resorted to acquiring faster means of transporting people and goods. Increasing number of vehicles coupled with haphazard city planning and unscientific road designs has resulted in making the general public vulnerable to road accidents every year.

Based on the assessment of the road safety data, it can be concluded that limited road safety statistics are available and even less is known about the accident causes, especially when it comes to accidents involving trucks. In case of available data, it can be concluded that the data are not harmonized (e.g. vehicle class and definition of truck, pick-up, and weight) between countries and that in many cases the figures outdated (Dr. Cumhur Aydın,
