NHTSA (The National Highway Traffic Safety Administration) is a US agency of the Executive Branch of the U.S. Government, part of the Department of Transportation.
I know that Toyota doesn't sell Land Cruiser 120 Prado in the US, but Toyota sells Land Cruiser 200 (V8) there.
So, may be Land Cruiser safety is rated there?
No, it's not. You can check it here.
