The number of collisions between motor vehicles and moose is increasing in many countries. Collisions with large, high animals such as moose cause typical rear- and downward deformation of the windshield pillars and front roof, most pronounced for small passenger cars; the injury risk increases with the deformation of the car. A strengthening of the windshield pillars and front roof and the use of antilacerative windshields would reduce the injury risk to car occupants.
