According to the Workzonesafety.com, nearly half (46%) of all work zone-associated worker fatalities from 2003-2010 were caused by being struck by a vehicle. Surprisingly, only around 2% of those workers were killed by a drunk driver.  From 2003 to 2015 (the last year this data was updated), a total of 1324 work zone fatalities have been recorded, which averages to about 102 per year.
