Rocky IV” star Brigitte Nielsen was rushed to the hospital after a 3-car smash-up in L.A. last night — and cops believe the person who caused the wreck was driving while hammered.

Law enforcement sources tell … Nielsen was a passenger in a 2006 Porsche Cayenne … which was struck from behind around 10:20 PM by a woman driving a Toyota Matrix. 

We”re told the Porsche was knocked forward … striking the car in front of it.

Cops and paramedics were called to the scene — and the Matrix driver was arrested for DUI. Sources tell us the woman blew WELL ABOVE .08 on a breathalyzer test.
