Bobby Brown -- I'm Gettin' the Hell Outta Dodge

Here's Bobby Brown getting ready to board a plane at LAX yesterday ... just a few days after getting arrested for DUI in L.A.

It's unclear where Brown was headed ... but it's obvious why he's not driving to his destination.

TMZ broke the story ... Brown allegedly blew a .12 when he was popped for drunk driving in the middle of the day on Monday ... and cops say he was also driving on a suspended license.

If convicted, Brown could do some serious jail time.
