A Grantham man admitted that he drove over the alcohol limit on Springfield Road.
Simon Topham, 35, of Dysart Road, Grantham, pleaded guilty to driving with 70 microgrammes of alcohol in 100 millilitres of breath.
On December 21 police received a report of a possible drunk driver in a Volkswagen Golf, which they stopped on Springfield Road.
Topham complied and after giving a positive roadside breath test he was taken to the police station.
Representing himself in court, Topham described it as a ‘silly, silly mistake’ and said that it wouldn’t happen again.
He was disqualified from driving for 18 months, with the opportunity to reduce this by four months if he completes a drink driver’s rehabilitation course.
Magistrates also ordered him to pay a fine of £190, prosecution costs of £85, and a victim surcharge of £20.
