Which U.S. government agency oversees travel including air and rail?

• A. Department of Transportation (DOT)
• B. Federal Aviation Administration (FAA)
• C. Transportation Security Administration (TSA)
• D. National Transportation Safety Board (NTSB)

Answer: (A)

The question is about which federal body has responsibility for overseeing travel across multiple transportation modes. The Department of Transportation serves as the umbrella agency for national transportation, including both air and rail travel. Within it, agencies like the Federal Aviation Administration handle aviation safety and airspace, while the Federal Railroad Administration oversees rail safety and regulation. That broader, cross-modal oversight is why the Department of Transportation is the correct answer. The FAA is focused specifically on aviation, TSA handles security screening, and the NTSB investigates accidents, not regulate overall travel.
