What is the leading cause of injury and death in roadway work zones?

Answer: B — Speeding traffic

Speeding traffic is recognized as the leading cause of injury and death in roadway work zones due to the unique hazards presented in such environments. Work zones often feature narrow lanes, shifting traffic patterns, and the presence of workers and heavy equipment. When drivers exceed speed limits in these areas, they significantly reduce their reaction times and increase the severity of crashes. The enforcement of reduced speed limits in work zones is vital to ensure the safety of both workers and drivers. In many regions, penalties for speeding in these zones can be more severe than for regular speeding to emphasize the heightened risks involved. By adhering to speed limits, drivers can better navigate the complexities of work zones, leading to a safer environment for everyone involved.
