The most lethal threat to highway zone construction workers is the possibility they will be struck, either by a passing car or construction vehicle. In 2017, 132 individuals working in highway construction zones were killed in this way, reported the Federal Highway Administration. With the exception of 2012 and 2016, during which 133 and 143 workers, respectively, were killed in highway zone crashes, 2017 saw the highest number of fatalities in a decade.
