Abstract:Data from the 2023 Crash Investigation Sampling System (CISS) shows there were an estimated 2,555,023 police-reported motor vehicle traffic crashes nationwide where at least one passenger vehicle (i.e., passenger car, light truck, or van less than 10,000 lb) was towed from the crash scene, which resulted in an estimated 1,043,485 injured occupants of in-transport towed passenger vehicles. Among these crashes, 2.6 percent (67,042) were crashes with the highest injury levels of serious or above, 21.2 percent (540,690) were crashes with moderate or minor injury levels, and 59.5 percent (1,520,405) were crashes with no injury. In 2023 CISS selected 4,636 police-reported crashes. Of the 4,636 selected crashes, 3,997 were eligible for investigation. In 2023 motor vehicle traffic crashes that involved at least one passenger vehicle towed from the scene of the crash were sampled, investigated, and coded at 32 selected sites across the Nation. Statistical weighting procedures generated nationally representative estimates of relevant crashes. This research note presents a summary of key estimates of crashes in 2023.
