Suge Knight -- ARRESTED Again

Suge Knight was arrested early Wednesday morning just outside the Bev Hills border ... TMZ has learned.

LAPD cops noticed Suge straddling 2 lanes at around 12:30 as he tooled along in his truck ... which had no license plates. The Death Row Records founder was pulled over and police quickly determined he was stone cold sober ... which was good.

Here's the problem. It seems Suge didn't appear in court for one of those pesky crimes of driving on a suspended license, so a warrant was issued for his arrest.

So Suge was chauffeured to a nearby jail in the back of a black and white. He's still there ... on $20k bail.

7:20 AM PT -- Suge has been released from custody after posting $20k bail.
