Collisions of heavy trucks against cars, two- wheelers and pedestrians.

Collisions of heavy trucks with cars, two-wheelers and pedestrians are analyzed with regard to their frequency, their injury potential and collision mechanisms. 129 crashes of trucks with other four-wheel-vehicles (totally 163 injured occupants and 247 vehicles) were analyzed in detail. The most dangerous impact configuration was truck-front to car-front; therefore deformable underrun protection elements in the front would have a much higher injury reduction potential for car occupants than the classical rear underrun protection bars.
