A DRINK driving offence was detected after a motorist passed Antrim PSNI Station without headlights on at 11.50pm on May 6 this year.
Kieran Fanning (50), of Oakglen in Antrim town, admitted driving with excess alcohol.
Antrim Magistrates' Court, sitting in Ballymena, was told officers leaving the police station spotted the absence of lights and then stopped the vehicle.
The defendant had an alcohol in breath reading of 84 - the legal limit is 35.
A defence lawyer said a reference from the defendant's employer speaks "very highly" of him.
The lawyer said the defendant, who had a previously clear record, was aware of his "foolish behaviour".
The lawyer said the defendant had an argument on the night in question and had left to "clear his head".
Deputy District Judge Austin Kennedy said there could have had been "far more serious repercussions" given that the lights weren't on.
The defendant was banned from driving for a year and fined £500.
