According to law enforcement ... Knievel -- the son of the legendary Evel Knievel -- caused a brutal 4-car pile up on a Montana road and fled the scene Tuesday night after blazing around drunk as a skunk ... no injuries were reported.
Knievel was rounded up by cops within a block of the crash standing outside his vehicle and allegedly smelling like booze but he refused the breathalyzer and they hauled him in for a blood test.
As you may recall ... Robbie was busted back in 2013 for blowing 3x the legal limit in South Dakota and came on TMZ Live, unapologetically admitting he was a full-blown alcoholic.
As of Wednesday morning he was still in police custody.
