A banned driver who gave gardai a false name was found out when officers found a card bearing his real name in his car.
John Joyce (33) was spotted by an off-duty garda who contacted his colleagues and they stopped him.
Judge John Cheatle imposed a four-month sentence and disqualified Joyce from driving for five years.
The defendant, of Drynam Avenue, Kinsealy, admitted driving without insurance or a licence on the M1 in Lusk last April 26.
Gda Con Kennedy told Swords District Court that an off-duty garda raised concerns about a man driving a 2007- registered vehicle at an Applegreen petrol station on the M1.
Gda Kennedy said officers went to the scene and stopped Joyce, who gave officers a false name and address.
The officer said a card containing the defendant's real name and address was found in the car.
The court heard that Joyce had 111 previous convictions, including 17 for uninsured driving.
Defence solicitor Fiona D'Arcy told the court her client was selling a car at the petrol station.
She said he gave the wrong name because he was confused by what the garda was asking him.
She said Joyce's wife had arthritis and found it difficult to drive, and she relied on him to do household chores.
The court heard that Joyce was due to start a new job on a building site.
Ms D'Arcy said many of the defendant's previous insurance convictions stemmed from when he was a teenager and was "forced to drive by older members of his family".
Recognisances were set for an appeal.
