I think they're road accidents.
With a rate of 14.6 fatalities per 100,000 FTE workers, transportation and material moving occupations had the most fatalities in 2022 (1,620), up from 1,523 in 2021. The increase was due to fatalities to driver/sales workers and truck drivers increasing by 8.0 percent, from 1,032 fatalities in 2021 to 1,115 in 2022.
