The year of Randy Travis' demise has taken another dark turn.  He was arrested late Tuesday night on suspicion of driving while intoxicated . . . AND for "retaliation and obstruction."

It happened in Randy's hometown of Tioga, Texas, about an hour north of Dallas.

Someone called the police at 11:18 P.M. about a man lying in the street.  When the cops got there, they found Randy's Trans Am had been driven off the road, through several barricades, and into a construction zone.

And they also found Randy . . . NAKED . . . with a black eye . . . and covered in cuts and bruises.  All of that was most likely from the crash, but we're not sure.

Police said Randy, quote, "had a strong odor of alcoholic beverage on his breath and several signs of intoxication."  

He was arrested and put in the squad car . . . and THAT'S when he made threats to KILL the troopers.  Huge mistake, because that's a felony that carries a maximum penalty of 10 years in prison, and a possible fine of $10,000.

At that point the cops hauled him off to jail, quote, "still naked."  Although they were kind enough to give him one of their shirts and a paper suit for him to wear for the mug shot.

After spending the night locked up, he was arraigned and released on $21,500 bond yesterday morning.

Prosecutors are still deciding if they're going to proceed on the misdemeanor DWI charge.  The felony "retaliation and obstruction" charge will go to a grand jury, and that could take up to six weeks.

Randy's people have yet to comment.
