A driver more than twice the legal alcohol limit overshot a junction, veering across the road and into the path of a police car.
There was no accident but police followed and stopped Richard Partridge after he drove on and turned into West Street, Bourne.
Rebecca Ritson, prosecuting, said the incident happened shortly after 3am on March 10.
Partridge had 87 microgrammes of alcohol in breath – the legal limit is 35mcgs.
Spalding magistrates on Thursday banned Partridge from driving for 20 months and imposed a £300 fine with an order for £85 costs and a £30 victim surcharge.
He can cut 20 weeks off the ban if he completes a rehabilitation course.
Partridge, of Kendrew Barracks, Oakham, was not represented by a solicitor.
He told the court: “I am sorry. It was a stupid thing to do.”
