(TMZ) - 11:36 AM PT THURSDAY -- Justin left the jail just moments ago ... climbing on top of an SUV and waving to a crowd of fans.
Law enforcement sources tell TMZ ... Justin blew a .04. That would not automatically make him a drunk driver -- IF he were 21 or older. But Justin is 19, and Florida has a zero tolerance for underage drinkers who drive ... and if he blows higher than a .02 it's an automatic license suspension.
Remember, he was arrested for DUI for both drugs and alcohol. If booze and drugs impaired his driving -- even if it was just a sip of liquor -- he can be convicted of DUI.
Justin Bieber was arrested for DUI and it wasn't pretty -- cops say Justin was wasted and resisted arrest and cussed the cop out, dropping multiple F bombs ... TMZ has learned.
