Which federal agency oversees roadway work zone safety?

The Federal Highway Administration (FHWA) is the correct answer because it specifically focuses on ensuring safe and efficient transportation systems, which includes oversight of roadway work zone safety. The FHWA provides guidance, standards, and support to state and local agencies in managing work zones and minimizing hazards for both workers and motorists. Their policies and regulations aim to enhance safety on highways and roadways, which directly impacts the management of work zones during construction activities.

In contrast, the other agencies listed focus on different areas. The Federal Bureau of Investigation (FBI) is primarily concerned with law enforcement and criminal investigations, not traffic safety. The National Highway Traffic Safety Administration (NHTSA) does address vehicle safety and driver behavior but does not oversee work zone operations specifically. The Federal Transportation Authority (FTA) is focused more on public transportation systems and does not deal with roadway work zones. Thus, the FHWA is uniquely positioned to manage and guide roadway work zone safety initiatives.
