Using the Collision Deformation Classification (CDC) (SAE J224), a comparison of the National Accident Sampling System (NASS) data and the University of Michigan Transportation Research Institute (UMTRI) field accident files (UM series) indicates a similar distribution of offset frontal crashes. Offset frontal damage occurs in 56-61% of crashes, often involving more than one third of the front of the car. Lap-shoulder belted drivers sustain more Abbreviated Injury Scale (AIS) 2 or greater injuries when there is interior intrusion. These injuries occur more often when the offset damage is in front of the driver. However, this may well be due to the severity of the crash. European studies have studies have no uniformity as to offset frontal collision descriptors are difficult to interpret, or to compare one to another. (A)
