A policeman who spoke to a woman following an argument with her partner later spotted her behind the wheel and “presumed she may be over the limit”.
Kelly Edwards (35), of Mill Green Road, Pinchbeck, was found to have 83mgs of alcohol in blood – 3mgs over the limit.
She pleaded guilty to driving with excess alcohol on Mill Green Road on November 30 when she appeared before magistrates at Boston today (Wednesday).
Edwards was banned from driving for a year, fined £110 and ordered to pay £85 costs with a £20 victim surcharge.
She can cut 13 weeks off the ban if she attends a rehabilitation course.
Prosecutor Nick Todd said a policeman saw her Honda Accord at about 6.20pm.
He said the officer had been in conversation with her an hour or two earlier when he noticed that she’d had a drink.
Solicitor Mike Alexander, mitigating, said: “She had an argument with her partner and that caused the officer to come round and speak with her in the first place. She was upset – she tells me she didn’t think she would be over the limit at all. You have heard how close she was to the limit.”
