A man who had been drinking on his day off responded to an unexpected call to go to work in Spalding.
But Piotr Kotynia (32) was more than double the drink-drive limit when police saw his Mitsubishi swerve over white lines in the road, magistrates heard.
Marie Stace, prosecuting, said police spotted Kotynia’s car on John Adams Way, in Boston, at 10.56pm on March 14.
His car swerved over white lines and police followed and stopped him.
Solicitor Beris Brickles, mitigating, said Kotynia works at Emmett’s in Spalding and had been drinking on his day off when he received a call during the late hours of the evening.
“Not wishing to give up that employment, he stupidly decided to drive,” said Mr Brickles.
Kotynia, of Rose Place, Boston, admitted driving with 71 microgrammes of breath. He was banned from driving for 20 months, fined £180 and must pay £85 costs and a £20 victim surcharge.
Boston magistrates on Wednesday said they will allow Kotynia to cut the ban by five months if he undertakes a rehabilitation course at his own expense.
