Trucking industry expert witness Robert R. Reed writes on Truck/tractor-trailer crashes:
The investigation of large truck crashes can be complex and overwhelming for inexperienced or inadequately trained personnel. Past practices have shown that some truck crash investigations have been conducted inadequately, producing erroneous and incomplete information. Some reasons for this are the complex systems and advanced technology in modern trucks that are not processed at the crash scene or the follow-up reconstruction effort. The statistics of approximately 100 people killed each week across the country and vast numbers of serious injuries and 409,000 police reports of crashes involving large trucks in 2001 dictates that adequate training and procedures are used so thorough investigations are completed using all data available.
