A detective garda has been convicted of dangerous driving following a crash on the M50 just over two years ago.
Detective Garda Kevin Keys, who is attached to Mountjoy Garda Station in Dublin, admitted he lost control of the car on the evening of 6 February 2010.
But he pleaded not guilty to dangerous driving.
His solicitor asked the court to find that the prosecution had not proved that Garda Keys was guilty of dangerous driving beyond reasonable doubt.
Dara Robinson said there was a possibility that the lesser charge of careless driving had been made out.
However, Judge Conal Gibbons said he had no doubt that the prosecution had proved that Garda Keys was guilty of dangerous driving, taking into account the conditions at the time, the speed and the description of what happened from the driver Garda Keys crashed into.
He disqualified Garda Keys from driving for two years and fined him €500.
The judge earlier dismissed a charge of taking the unmarked garda car without authorisation.
He said to call the arrangements for taking a car from Mountjoy "loose" would be an understatement.
