Transportation Safety Accidents Ntsb Eslpod National Board U.S

The National Transportation Safety Board (NTSB) is a U.S. government "agency" (department or organization) responsible for "investigating" (researching; determining what happened) accidents on "highways" (wide roads for fast-moving cars), railroads, ships, and airlines. It also investigates "pipeline incidents" (problems related to the long tubes that carry oil, natural gas, and other substances for long distances) and accidents in which "hazardous materials" (substances that can cause injury, illness, or death) are "released" (allowed to escape), such as when a "tanker truck" (a large vehicle that carries liquids) "leaks" (allowing a liquid to escape) dangerous chemicals.

The NTSB is based in Washington, DC and has four "regional" (related to or located in a particular location) offices in Alaska, Colorado, Virginia, and Washington. It was created in 1967 as part of the Department of Transportation, but "Congress" (the part of the U.S. government that makes laws) soon "established" (created) it as an "independent agency," meaning that it is not directly connected to other parts of the "federal" (national) government. This was done to be sure that it could be "unbiased" (without already having certain opinions or a need to find certain results) in its investigations.

The "mission" (purpose; reason for being) of the NTSB is to "determine" (identify) the "probable" (most likely) cause of transportation accidents and "incidents" (events that have negative consequences) and to "formulate" (develop; create) safety "recommendations" (suggestions for ways to make something better) to improve transportation safety." The NTSB has "issued" (made; released) more than 14,000 recommendations, and about 73% of them have been "implemented" (adopted and followed).
