Chris Kattan seemed wasted as he drove on the 101 Freeway, just before he careened into a coned area and crashed into a parked vehicle ... this according to the 2 people who called 911.
TMZ broke the story ... Chris was popped early Monday morning after other drivers sounded the 911 alarm. After weaving at speeds approaching 70 MPH, he crashed into a Dept. of Transportation vehicle. Chris was arrested for DUI and law enforcement sources tell us Chris admitted he was on Rx meds.
One 911 caller says it seemed to him, "He has to be drunk."
Turns out alcohol was not a factor, but Chris seemed to have been under the influence of prescription meds earlier in the day ... on a flight to L.A.
