A 57-year-old Helena woman is accused of driving while under the influence.
Lorraine Wallace Bigelow is being charged with a fourth DUI, a felony, and a misdemeanor charge of careless driving.
On March 12, a deputy observed a vehicle driving in the center turn lane of Montana Avenue and then pulling into the Valley Hub, court documents say.
The deputy spoke with Bigelow, who told him that she had been driving in the center lane because she could not see the lines on the road, according to court documents.
Bigelow allegedly told the deputy that she was unable to do any of the sobriety tests due to medical issues and then refused to provide a blood or breath test, according to court documents.
