A discussion of the technical analysis of accident scene evidence distinguishes between elements of the traditional police approach to accident investigations and the engineer/investigator approach to accident reconstruction. Another section of the training pamphlet notes the importance of the police role in collecting evidence at the accident scene that can later be used by experts in reconstructing the accident. A case study details the evidence used to reconstruct a particular accident. The remainder of the pamphlet focuses on elements of roadway analysis, although it is advised that a detailed methodology for collecting and recording accident scene evidence is not practical. Instruction is provided in depicting the accident location and recording the immediate surroundings. Detailed guidance is provided for examining and recording road marks produced by the accident, including recent gouges, scrape marks, and other deformities in the road surface. The handling of fluids and vehicular debris found on the road is also described, along with the documentation of tire marks, skid marks, and side-slip marks. A discussion guide and test questions and answers are provided.
