A woman made an obscene gesture toward an SUV Monday - one carrying the county sheriff and chief deputy - and ended up in jail, police said.
Mary Ann Sweeney, 33, of Evansville was stopped behind a bus.
She pulled to the left to get around the bus at the same moment a Ford Explorer started to pass. The SUV braked to let her in, police said.
Sweeney then "flipped off" the Explorer's driver, Vanderburgh County Chief Deputy Eric Williams, he said. The passenger was Sheriff Brad Ellsworth.
The Explorer was marked as a sheriff's vehicle, but did not have a light bar on top, police said.
Ellsworth and Williams pulled Sweeney over to talk to her about her "road rage" and ran a check on her license plate.
They found that both she and her husband, Jerry DeWayne Sweeney, were wanted on outstanding civil warrants for $500 each, and that the car was illegally registered, police said.
Ellsworth said they found marijuana in the car and in the woman's purse and cigarette pack. Mary Ann Sweeney also was charged with misdemeanor marijuana possession.
The couple was taken to the Vanderburgh County Jail and later bonded out.
"I guess the moral of the story is, if you have warrants against you, you shouldn't flip off the police," Ellsworth said.
