When people look for new cars they often are interested in the federal crash test ratings. Unfortunately, those ratings had reached the point where so many vehicles were highly rated that differentiating between them was becoming impossible. Also a number of crash-types were not even evaluated.
So, when the United States Department of Transportation and the National Highway Transportation Safety Administration announced new tests and concomitant ratings it was a significant development. http://www.nhtsa.gov/About+NHTSA/Press+Releases/2010/U.S.+Transportation+Secretary+Ray+LaHood+Rolls+Out+Upgraded+5-Star+Vehicle+Safety+Ratings+System
It will take a while for the comprehensive evaluation of all vehicles but a trip to http://www.safercar.gov/ will get you started.
