THAT'S SOME BULLSH!T RIGHT THERE! DASH CAM RECORDS NAS GETTING A SOBRIETY TEST! YOU CALL TELL THESE COPS WERE THIRSTY!

TMZ has obtained police dash cam footage showing rapper Nas failing several DUI field sobriety tests back in September. He was cleared of the charges -- but does he look sober to you?
As we first reported, Nas -- aka Nasir Jones -- was pulled over in Georgia back in September after driving erratically. Cops say he was carrying a sack of weed and sporting a green tongue ... unfortunately, you can't see that part in the video.

But you can see Nas wobble during a balance test and take the wrong number of steps during the "walk the line" test -- yet still, authorities decided it wasn't enough evidence to convict.
