After years of focusing on driver behavior, the figures still show that fatal outcomes involving large trucks are shaped just as much by where crashes happen as by what drivers do. For example, $103 billion in total societal cost has been reported for crashes involving large trucks in a federal safety economic study, even as nearly all fatal wrecks are not evenly distributed across streets, intersections, and rural roads. When 54% of people killed in large-truck crashes were vehicle occupants other than the large truck, the “who is at risk” question stops being abstract and starts demanding a close look at the dataset.

- The U.S. federal government estimated that serious crashes could be reduced by 9% due to ELD compliance (FMCSA Regulatory Impact Analysis) — quantified potential safety benefit
- In a 2019 meta-analysis, sleep loss increases risk of motor-vehicle crashes by ~2-fold — quantitative risk magnitude from a study
- In 2020, 16.4% of hours on the road for long-haul drivers were spent driving while drowsy (survey study estimate) — quantified drowsy-driving exposure
