DMX Arrested -- Get Off the Road! Busted Behind the Wheel Again

Rapper DMX needs a professional driver to keep him out of jail -- he just got arrested ... again ... for three offenses while driving at the airport in South Carolina.

Law enforcement sources tell TMZ ... DMX -- aka Earl Simmons -- was pulled over by cops at the airport in Spartanburg, SC and nailed for driving on a suspended license, driving while uninsured, and driving an unlicensed vehicle.

A rep for the Greenville-Spartanburg International Airport says officers noticed DMX as soon as he pulled up to the terminal -- and were apparently well versed on his track record.

X is familiar with the suspended license charge -- he's been slapped with that one multiple times. His most recent busts were for allegedly possessing weed (in Aug.) ... and an alleged DUI (in July).

DMX is still in custody, and will have to see a judge -- with whom he's probably on a first name basis -- before he can get out.
