Crash Investigation 2 Online is asynchronous and instructor led. At-scene traffic crash data collection is useful only if all appropriate data is properly collected, interpreted, and analyzed. Officers and investigators who successfully complete Crash Investigation 2 develop skills in technically preparing crash investigation data and collecting follow-up data. Building upon topics examined in Crash 1, students delve further into the information available at a crash scene, how to properly collect it, and how to initiate its interpretation. Like Crash Investigation 1, the course is rooted in Baker and Fricke’s Traffic Crash Investigation and emphasizes vehicle behavior in crashes, vehicle damage analysis, advanced measuring and mapping, properly downloading and preserving digital evidence from collision investigations, examining road marks and tire damage, and more.
