From the article: "Despite billions spent on safety technology, fatal truck-involved crashes are up ≈40% since 2014—almost entirely because of untrained, overworked, and inexperienced drivers now operating 80,000-pound rigs."
From a quick analysis, non-trucker fatalities per mile was about even or slightly increased from 2014-2023. I would conclude it’s not worse than it appears in the trucking situation.
Directionally this still looks accurate, and give thousands of truck driver deaths per year, its significant.
