A 53-year-old Billings woman has admitted to what prosecutors say is her sixth drunken-driving offense.
Doris Valerie Wynn Rose appeared Thursday in District Court and pleaded guilty to felony DUI and misdemeanor counts of driving without a valid license and driving without insurance.
A plea agreement states prosecutors will ask Judge Susan Watters to sentence Rose to 10 years at the Montana Women's Prison as a persistent felony offender and pay a $2,000 fine.
Prosecutors also will ask that Rose not be eligible for parole until she has completed a state alcohol treatment program.
Prosecutors will ask that Rose receive concurrent jail terms for the misdemeanor charges. A sentencing hearing was set for April 25. Rose remains in the county jail on a $50,000 bond.
Rose was arrested last Oct. 25 after a Montana Highway Patrol trooper stopped a car that was going 25 mph under the speed limit on Blue Creek Road. The trooper said the driver also drifted into the oncoming lane while making a turn.
A breath test showed Rose had a blood-alcohol level 0.272 percent, more than three times the legal limit.
Rose has two prior felony DUI convictions and a conviction for escape.
