A college lecturer driving home from his snooker night was over the legal alcohol limit.
Police saw Paul Graves (59) at Gedney Hill in the early hours of February 28.
John Clare, prosecuting, told Spalding magistrates the car appeared to brake on a number of occasions “for no good reason”.
Graves had 50 microgrammes of alcohol in breath, 15 over the legal limit.
Graves, of New Cut. Thorney, was fined £465 for drink-driving with a 12 month ban. He can cut three months off the ban if he completes a rehabilitation course.
He pleaded guilty. Graves must pay £85 costs and a £46 victim surcharge. Magistrates imposed no separate penalties for offences of no insurance and no MOT.
Graves said he intended to leave the car with someone else that night, but the person was not at home.
