A 25-year-old drink-driver has been fined £1,000 and banned from driving for two years.
Glorybeth Donegan admitted the offence after she failed a breathalyser test with a reading of 56. The legal limit is 35.
High Bailiff Jayne Hughes also ordered Donegan to take an extended test at the end of her ban.
Prosecuting advocate Barry Swain told the court that Donegan was seen by police, driving a blue Vauxhall car on Woodbourne Road on August 27 at 3.30am.
The vehicle was said to be swerving and its road position when stopped at traffic lights was described as poor.
Police subsequently stopped the car and Donegan, who lives at Alder Grove in Douglas, was said to be smelling of alcohol.
She told police that she had been at 1886 bar and had drunk some Tequila Rose around three hours ago.
Donegan failed a roadside breathalyser test and was subsequently arrested and taken to police headquarters, where she blew the reading of 56.
Defence advocate Paul Glover asked for credit to be given for his client’s guilty plea and the fact that she had no previous convictions.
Mr Glover said that it had been a quiet time of night, there had been no injuries or damage caused, and Donegan had fully co-operated with police.
High Bailiff Jayne Hughes told Donegan: ‘Alcohol stays in the system a lot longer than most people think.’
Donegan was also ordered to pay £125 prosecution costs which she will pay, along with the fine, at a rate of £100 per month.
