Julie Holland, 43, of Hessle Drive, was driving home from Boston Police Station with her 16-year-old son when she was stopped by police at around 4am on November 1.


The officers thought she was speeding, but soon, she was back at the station after failing a roadside breath test, prosecution solicitor Stephen Hill said.


There she gave a reading of 57 micrograms of alcohol in 100 milliliters of breath – the legal limit is 35 mcg.


Holland pleaded guilty to drink-driving at Boston Magistrates' Court on Wednesday.


In mitigation, Andrea Clarke described a set of 'rather peculiar circumstances' behind the offence.


Her client had been sharing a bottle of wine at her sister's home, where she had arranged to spend the night.


She then received a phone call from the police telling her that her son had been arrested, and an appropriate adult was needed at the station, Miss Clarke continued.


Her client told police she had been drinking, but received three more calls from them in half-an-hour – and with the father not responding to calls at all – she 'felt somewhat pressured, and drove to the police station', Miss Clarke said.


Miss Clarke added that the police did not offer to pick up her client, that she did not realise she was over the legal drink-drive limit, and in normal circumstances, would not have even drunk any alcohol if she was planning to drive.


Holland was banned from driving for 12 months, fined £200, and ordered to pay the £15 victim surcharge and £60 costs.
