Additional Information / Summary:

Although an impact with a pole or tree is probably the most common type of collision involving a vehicle and a fixed object, such a collision requires unique methods for examining the vehicle and taking measurements and employs special formulas based on work/energy for calculating the impact speed. Sgt. Cofone, with the Bergen County (NJ) Prosecutor's Office Fatal Accident Unit, explains how the investigator can conduct a successful investigation and apply the formulas (a computer is not needed) to arrive at a reasonable speed estimate wherever possible. He suggests which formulas may be most appropriate under certain conditions and provides a sample solution to a problem. Learn how to establish a baseline, measure vehicle crush, determine the PDOF, find published stiffness coefficients, determine the extent of vehicle bowing, and much more. The booklet also contains useful information about wooden utility poles and a glossary of technical terms.
