Along a slightly different line of thought, one could also make the distinction between risks involved as a passenger or driver of a certain type of vehicle, and the risks associated with the use of such a vehicle to other road-users.
In this way, lorries are a very safe means of transport to their occupants, because very few fatalities occur to drivers and passengers of lorries, both in absolute numbers and expressed as fatalities per vehicle-km travelled, but they are involved in a proportion of fatal accidents which is considerably larger than their share in vehicle kilometres driven. The same is the case for buses. Cars are also becoming safer and safer for their occupants, because most technological innovation and development has been applied to improve the safety of the occupant: US and European safety regulations, seat belts, air bags, etc. Thus the risk of being injured or killed per vehicle-km travelled continually decreases. However, the issue of injuries and fatalities caused by these vehicle to the vulnerable road-user are only now being addressed and still there are few technological developments that are effective.
