Christina Gee, 39, was booked into the Pima County jail on suspicion of aggravated assault and felony criminal damage March 28, authorities said.
Gee was found to be impaired by alcohol after officers conducted a DUI investigation. The charges resulted from the investigation, said Officer Dan Lucas, a Tucson Police Department spokesman.
The 17-year-old motorcyclist remains in critical condition at a local hospital.
The motorcyclist was traveling west on East Golf Links Road approaching South Sahuara Avenue. An SUV, driven by Gee, was traveling east and made a lefthand turn heading northbound in front of the motorcyclist.
The motorcyclist, who was wearing a helmet, struck the passenger side of the SUV.
