They believe it's the highest level ever recorded in Rhode Island for someone who wasn't dead.
The man was arrested early Tuesday morning after he drove his car into a highway message board on Interstate 95 in Providence. Troopers had to carry him to the breakdown lane before taking him back to their barracks.
A trooper says a Breathalyzer test registered blood alcohol readings of .489 followed by .491.
The man was released from custody after promising to appear at a court hearing Friday.
