S.C. Department of Transportation The S.C. Department of Transportation (SCDOT) is recognizing National Work Zone Awareness Week in conjunction with state transportation departments across the nation. National Work Zone Awareness Week started April 9. The recognition is held at this time each year to bring attention to motorists and highway workers, who are both at risk in work zones when safety is not practiced. SCDOT has launched a year-long work-zone safety campaign called “Let ’Em Work, Let ’Em Live.”
