A gym owner reversed into a parked car then crashed into a fence when she got behind the wheel while drunk.
Kayleigh Armstrong had been celebrating the success of one of her members in a marital arts competition when she drove her BMW in Blyth late one evening in November.
A concerned witness called the police after he saw the mum-of-two crash into a stationary vehicle and a fence, a court heard.
Officers arrived and Armstrong, of Scott Street, Cramlington, Northumberland, failed a roadside breath test, giving a reading of more than three times the legal limit, and was arrested.
The 32-year-old has now been banned from the roads for 26 months after she admitted driving with excess alcohol at South East Northumberland Magistrates' Court.
Prosecutor, James Long, said it was shortly before midnight on November 30 that the witness saw Armstrong arguing with a male on Carrside Mews, in Blyth.
"He sees the defendant enter a motor vehicle and reverse it, firstly, into a Ford Mondeo, pushing it 3m up the road," Mr Long added.
"The defendant then drives out to the street. The witness contacts the police, concerned that the driver was under the influence of alcohol.
"She's then seen to drive back into the street and reverses quite fast, this time crashing into a fence. The wheels of her vehicle were spinning, as she was trying to get out of the position she ended up in."
The court heard that Armstrong gave a breath test reading of 104 microgrammes of alcohol in 100ml of breath when the legal limit is just 35.
Alan Brown, mitigating, said Armstrong owned a gym in Cramlington and had gone to a social club on the night in question but hadn't intended on drinking.
Mr Brown said: "One of her members was taking part in a martial arts competition. He was successful and they celebrated that success and she decided not to drive home.
"She was, however, concerned about the safety of her car and where she left it, so decided to move it. She shouldn't have taken the decision to move it at all."
Fining her £600, District Judge Bernard Beglay said: "This had dramatic consequences, you know that as well as I do.
"By the same token, there's nothing to contradict what has been said about the shortness of distance driven, which is why I impose a fine."
