A roadside breath test showed a man was almost three-and-a-half times the legal limit, but he then failed to blow properly during the evidential test at a police station.
Liudas Pakalniskis (38) left a party in Spalding following an argument and decided to sleep in his car.
He drove through a red light and was stopped by police in Broadway just before 10pm on September 12, Boston magistrates heard on Wednesday.
Jim Clare, prosecuting, said the roadside test showed 119 microgrammes of alcohol in breath – the legal limit is 35mcgs.
He said Pakalniskis was taken to Boston Police Station, where he failed to provide a proper test.
“During the tests, he didn’t blow hard enough or kept breaking the seal with his lips on the mouthpiece of the machine,” said Mr Clare.
Pakalniskis pleaded guilty to failing to provide a specimen of breath for analysis and was banned from driving for 24 months, fined £200 and ordered to pay a £150 criminal courts charge, £85 costs and a £20 victim surcharge.
Pakalniskis, of Wide Bargate, Boston, can cut 24 weeks off the ban if he completes a drink-drive rehabilitation course.
Solicitor Mike Alexander, mitigating, said Pakalniskis was due to stay overnight at the friend’s house but there was an argument at the party and he decided to leave.
Mr Alexander said: “He had some bedding in the car and his plan was to move the car around the corner and sleep in the car.
“He accepts on this occasion he has done something stupid. He didn’t give it any thought. He drove his vehicle having clearly consumed some alcohol.”
The court heard Pakalniskis had no previous offences in the UK.
