EXCLUSIVE

Flavor Flav was arrested early Thursday morning in Las Vegas by highway patrol and got nailed for so many alleged crimes ... it might be easier to tell you what cops didn't pin on him.

Only sorta kidding, but here's what they booked him on:

-- DUI

-- Possession of marijuana

-- Open container

-- Speeding

-- Bogus registration

-- Driving with a suspended license

According to Nevada Highway Patrol, this all began when cops spotted Flav at 12:30 AM 2005 black BMW and going 73mph in a 45mph zone.

Flav was busted for speeding last year in NY on the way to his mother's funeral. When cops ran his license, they found it was suspended 16 times.
