A police worker with memory loss crashed on the motorway while she was over the alcohol limit.
Lisa Whitehead, a police community support officer, was described as going to bed at her home in Bolton sober, and having no idea how she came to be driving back from Blackpool after drinking.
Whitehead, 34, of Montserrat Road, Bolton, pleaded guilty to driving with excess alcohol.
She was banned from the road for 12 months and fined £110 with a £150 court charge, plus £20 victims’ surcharge.
Pam Smith, prosecuting, said police were called to an accident on the M55, at Blackpool, where Whitehead’s Citroen had collided with the off-side crash barrier. A blood test showed 132 milligrammes of alcohol in her body – 80 is the limit.
Adam Whittaker, defending, said his client, who was of previous impeccable character, had suffered escalating mental health issues and was currently off work on sick pay.
Mr Whittaker added: “She went to bed at home completely sober. She had no idea of how she came to be driving back from Blackpool after drinking. She did not set out to commit an offence. She has now surrendered her driving licence.”
A letter from Whitehead’s medical specialist was read by the magistrates.
