The Tottenham goalkeeper admitted the charge at Westminster Magistrates Court on Wednesday.
He ran a red light, and was seen veering towards parked cars.
Westminster Magistrates' Court heard officers spotted vomit in the auto, which was carrying an unnamed passenger, while Lloris, of East Finchley in north London, had to be helped from the vehicle.
For the defence, David Sonn said Lloris' "spectacular fall from grace was not lost" on the goalkeeper.
World Cup-winning captain Lloris had spent the evening with some of his worldwide team-mates but was found to have 80 micrograms of alcohol in 100 millilitres of breath.
His lawyer said Lloris knew he should not have been driving and had called a cab after a night out. Not only were you putting your own life at risk but also that of your passenger.
Manafort Reaches Preliminary Agreement with Mueller to Avoid Second Trial
Another trial was to begin later this month based on charges filed against Manafort past year in Washington , DC. The discussions between Team Manafort and Team Mueller reportedly went on for more than four hours on Thursday.
The court heard that the goalkeeper had been out at a restaurant that evening, where he had been bought drinks by other customers.
In a statement released on the day of his arrest, Spurs vowed to deal with Lloris internally and insisted the club "takes matters such as this extremely seriously". The legal limit in England and Wales is 35mcg.
"He had booked a taxi but unfortunately the taxi cancelled at the last minute", Sonn said.
France won their second World Cup with a 4-2 final victory over Croatia, although Lloris was guilty of a bad mistake that allowed Mario Mandzukic to score. He experienced the indignity of being handcuffed and put in a police station overnight.
Accompanied by two associates, Lloris was greeted at court by a media scrum but quickly navigated his way into the building. He joined Tottenham Hotspur in 2012 and has 108 appearances for the French national team.
"This kind of risky behaviour is selfish, illegal and puts lives at risk".
