ABSTRACT: There are hundreds of fatalities each year in emergency-vehicle-related crashes. These vehicles are often quite specialized with equipment and limitations very different from typical passenger cars. This presentation will discuss the investigatory aspects of dealing with one of these crashes.
-The vehicle (specifications, dynamics)
-The Driver (training, history, distractions)
-The Scene (sight distance, preemption, "right of way")
-Laws & Regulations (CDL / licensing exemptions, NFPA)
-Failure to Yield and Notice of Approach (SIrens/Lights)
-Measuring and understanding Sound
-Siren effectiveness (pressure, sweep, localization, shielding/reflection)
-Legal aspects of the crash aftermath
