The majority of work-related MVC fatalities occurred among occupants of trucks (67% of deaths), especially tractor-trailers (34% of deaths). Nearly half of all fatalities were collisions between two or more vehicles (49%), and 19% were non-collision incidents, especially jack-knifed trucks and overturned vehicles.[4] These statistics include only drivers and passengers in motor vehicles; U.S. data do include MVCs occurring off public highways, as well as fatalities of pedestrian workers, but these are not presented here. However, U.S. data on work-related fatalities do not include motor vehicle crashes while commuting to or from work, nor do crash data systems for the general population identify commuting status.
