The girl, aged 17, who cannot be named because of her age, was found to have 51 microgrammes of alcohol in her breath compared to the legal limit of 35.
She appeared in custody at Flintshire Magistrates' Court at Mold last Thursday, and was made t
he subject of a referral order by district judge Gwyn Jones.
He also banned her from driving for a year and ordered her to pay £60 after she admitted drink driving, having no insurance and not driving in accordance with a licence.
She also admitted failing to turn up at a youth court in Wrexham on an earlier occasion.
Staff at the McDonald's food outlet at Chirk contacted police at 3am on August 12 because they were concerned about a vehicle which had just left the premises, containing two people.
Police saw it parked on the A483 in Chirk and her boyfriend was behind the wheel at that stage.
However, the girl admitted that she had driven there and was breath tested, explained Justin Espie, prosecuting.
Defending solicitor, Melissa Griffiths, said that her client had not told her mother about the proceedings.
She had failed to turn up at the youth court but believed she should attend an adult court with her boyfriend, who had also been prosecuted.
It was her own admissions which had led to the prosecution because no one had seen her driving, said Miss Griffiths.
"Her judgment was clouded by the alcohol she had taken and she took a chance," she explained.
The judge made an order under the Children and Young Persons' Act that the girl, who comes from the Chirk area, should not be publicly identified.
