A banned motorist was jailed for ten weeks after being caught drink-driving for the fourth time.
Dulip Singh, 65, was stopped by police officers who saw him fumbling when opening a car door, the city's magistrates' court heard.
He was soon stopped and said he had downed two pints of beer. The court heard he thought his previous drink-drive ban had ended because it was imposed two years six months ago.
District Judge Leo Pyle told him: "This is your eighth conviction for a similar offence and the fourth drink drive conviction.
"You know better than anyone in this courtroom that you need to check that after a drink-driving conviction that the period of disqualification has expired."
A three-year driving ban will begin after the prison release of Singh of Lewindon Court, Woodthorpe.
He admitted driving while disqualified and having 40 micrograms of alcohol in 100 millilitres of breath. The legal limit is 35.
Sarah Sanderson, prosecuting, said police officers noticed Singh approaching a car at 6.45pm on May 3.
"This was due to the manner in which he walked towards the vehicle.
"He was unsteady on his feet. He appeared to fumble at the door, then opened the car door, got in and pulls off.
"He was driving for a short distance before the police were able to stop him. He smelt of alcohol and said he had two pints of beer.
"He was disqualified until May next year but said he thought the driving ban had expired," added Miss Sanderson. Singh was stopped on Mansfield Road in Sherwood.
Louise O'Driscoll, mitigating, said that Singh had arranged insurance cover for the car because he was so sure that his last disqualification had ended.
"There is no underlying issue with drinking. He describes being a social drinker. He had two pints on this occasion and blew just over the limit.
"He is very remorseful for his action and apologises through me to the court," said Miss O'Driscoll.
Singh must pay a government surcharge of £115.
