Vince Young DWI Video ... Frustrated, Uncooperative ... 'Are We Going to Jail or Not?'

Vince Young straight threw in the towel during his '16 drunk driving arrest -- refusing to complete field sobriety tests after getting frustrated with the cop ... and ultimately saying, "Are we going to jail or not?"

TMZ Sports obtained the arrest video from January 24, 2016 which shows Young being pulled over in Austin, Texas, after the officer says he was driving erratically in his white truck.

Young starts off being nice and cooperative ... but gets increasingly frustrated with the DWI investigation process.

He refuses to get out of his car until the officer orders him out.

He gets sick of the eye test and tells the officer he won't comply.

At one point he says, "What's the problem? Are we going to jail or not?"

The officer finally gets fed up when Young refuses a breath test and arrests the ex-NFL star.
