        Driver 01

        • The driver was 65 years old and holds a driving licence for 20 years.
        • He stated that he was dazzled by the sun. Then, he used the windscreen washing system. As a result, the windscreen became completely nontransparent for a short period of time and the driver couldn´t see anything. In that particular moment, he collided with the trailer.
        • Slight injured by the impact, marks caused by the airbag and seatbelt (bruise of the thorax AIS 1)
         

        • Front passenger, female, 68 years old.
        • Serious injured by the impact, marks caused by the airbag/seatbelt, impacting marks (deformation) at the right dashboard (serial rib fracture AIS3, distortion of the cervical spine AIS1, cut left finger AIS1)
         

        • Passenger second row right, female, 32 years old
