If convicted, it would be the 36-year-old woman's fourth OWI offense.
Troopers were called to the scene on I-94 westbound near Barker Road around 5:15 p.m. and determined one vehicle rear-ended another.
The driver of the striking vehicle – which sustained "heavy" front-end damage – showed signs of impairment, officials said, and was arrested after failing standardized field sobriety tests.
After an evidentiary blood draw was taken at a hospital, the woman was taken to the Waukesha County Jail. There, she was held on allegations of:
- Operating while intoxicated (4th offense)
- Resisting/obstructing an officer
- Throwing/discharging bodily fluid at a public safety worker
- Following too closely
