*Involvement does not always imply causation. Also, in some cases, the large truck struck another vehicle, pedestrian or object. In other cases, another vehicle struck the large truck.
 

**Approximately 38 percent of pedestrian fatalities in work zones each year are actually roadway workers who are struck and killed by vehicles. Also, in some cases the driver of the vehicle, rather than the pedestrian involved, was the person killed. As a result, the number of pedestrian-involved fatal crashes in work zones may be higher than the number of pedestrians killed in work zones.
 

***Worker fatality numbers from Bureau of Labor Statistics include both traffic-related and non-traffic-related occupational accidents.
