Jayson Williams -- Ex-NBA Star Arrested ... Drunk Driving Crash

Former NBA star Jayson Williams -- the guy who shot and killed his limo driver in 2002 -- was arrested in Upstate NY last week after cops say he drunkenly crashed his Jeep into a utility pole.

Officials say emergency responders were called around 11:30 PM on Jan. 26th to a single car crash -- and found the 47-year-old in his banged up Jeep.

Williams was transported to a local hospital to be treated for injuries -- and was ultimately charged with misdemeanor driving while intoxicated. You can see scrapes on his face in the mug shot.

Williams was released from the hospital a short time later.

It's not the first time Jayson has been popped for drunk driving -- in fact, he served time behind bars…
