Collision Damage Classification
Collision Damage Classification (CDC, per SAE MAR80 J224) is an excellent tool to provide a clear and concise description to the principal direction of force (PDoF) onto a motor vehicle during a vehicular accident investigation and reconstruction.
The standard was developed by the federal United States government to simplify the description of damage, where the direction of PDoF at point of impact (POI), vehicle deformation location, general type of collision, and damage scale are entailed and coded by numbers and letters.
