A Portland woman faces DUII charges after police say her car rolled into a TriMet bus while she was furiously dancing in the middle of a Beaverton street Tuesday night.

Della M. Still told police she had mixed marijuana with prescription medication before hopping out of her Ford Explorer on Northwest Cedar Hills Boulevard near Leahy Road to dance, Officer Jeremy Shaw, a Beaverton police spokesman, told The Oregonian/OregonLive.

As she boogied, her black SUV began to slowly roll backward -- and right into a No. 50 TriMet bus, damaging both vehicles, Shaw said.

The 35-year-old was still dancing when officers arrived around 10:45 p.m., police said. The officers also said they learned Still had managed to board the TriMet bus during the routine and throw herself onto the floor.

"Her behavior was pretty bizarre and erratic," Shaw said. "At one point, she was screaming at the top of her lungs."

Officers took Still to Providence St. Vincent Medical Center for an evaluation. She was later cited on suspicion of driving under the influence of intoxicants and released without being booked in jail.

"Clearly, we were concerned for her welfare," Shaw said.
