Authorities say a Helena motorcyclist with five prior DUI convictions had been driving with a blood alcohol concentration of three times the legal limit before running out of gas Sunday on Interstate 15.
Court documents say Kenneth Steven Berger, 58, was waving down traffic after he ran out of gas, and a state trooper stopped to help.
The trooper noticed Berger smelled of alcohol, and the man admitted to having three beers earlier that day, the documents note. After showing signs of impairment in field sobriety testing, Berger blew a 0.255 in a breath test.
A license check revealed the prior convictions, and Berger was jailed on a felony DUI charge.
