NTSB responsibilities cover which modes?

• A. Only Civil Aviation
• B. Marine, Railroad, Highway, Pipeline, And Civil Aviation
• C. Highway And Rail Only
• D. Marine And Pipeline Only

Answer: (B)

NTSB responsibilities span all major transportation modes to improve safety. The National Transportation Safety Board is an independent federal agency charged with investigating significant accidents and incidents across five modes: aviation, highway, rail, marine, and pipeline. It conducts investigations and issues safety recommendations for each of these areas, not just one sector. That broad mandate is why the option that includes marine, railroad, highway, pipeline, and civil aviation is the best fit. The other choices limit the scope to only one or two modes and don’t reflect the NTSB’s across-the-board role.
