Kareem Hunt had an open vodka container in his car, admitted he'd fail a drug test, and was chastised by a self-proclaimed Browns-fan cop during his speeding stop last week ... this according to new bombshell police video.
... Oh, and Ray Rice's elevator incident was brought up during the pullover too.
The footage, obtained by TMZ Sports, shows 24-year-old Hunt bolting down a freeway in his Chrysler in Rocky River, Ohio on Jan. 21.
You can see in the video, the Cleveland Browns running back blows by an officer .
