Did you know work zone fatalities are down 29.6 percent compared to 2003? Aggressive law enforcement and awareness campaigns and significant improvements to work zone safety traffic control reduced Illinois work zone fatalities from 44 in 2003, including 5 workers, to provisionally 30 with 3 workers killed in 2010.
So, Give ‘em a brake…slow down for their sake and yours!
