Crash student was still over the limit from party the night before
An architecture student "lost concentration" at the wheel of his car and drove on to the wrong side of the road, colliding with another vehicle, a court heard.
Rares Marin (26) had been at a party the night before and was heading home early the next morning.
He was still drunk, although he believed he was fit to drive, the court was told.
Judge David McHugh ordered Marin to complete 220 hours of community service in lieu of five months in jail, fined him €1,000 and banned him from driving for two years.
The defendant, of Luttrellstown Walk in Castleknock, Fingal, admitted before Blanchardstown District Court to drink-driving and dangerous driving on March 26 last year.
An application for the dangerous driving charge to be reduced to careless driving was refused by the judge.
Garda Errol Gill said he was called to the scene of an accident at Castleknock Road in Castleknock at around 8am.
Gda Gill said Marin had lost concentration and had travelled over on to the wrong side of the road and collided with an ongoing vehicle.
The other driver suffered minor injuries in the crash. His car was also damaged.
The defendant failed the roadside breath test, and he later provided a sample to gardai, which gave a reading of 161mg of alcohol per 100ml of urine.
The court heard that Marin had never been in trouble with the law before.
Defence solicitor Damien Coffey said that Marin was originally from Romania but he and his family had lived in Ireland for 17 years.
Mr Coffey said his client was studying architectural technology in IT Carlow, and had been in a relationship for seven years.
His father was a bus driver, while his mother worked as an accountant.
On the night in question, Marin had been at a party at a friend's house and had stayed the night. He got up the next morning and thought he was fit to drive.
Mr Coffey said Marin must have dozed off at the wheel for a moment or two and "everything happened very quickly" after that.
He said Marin wished to apologise for his behaviour, saying he realised he had made "one big mistake".
He also asked the judge to be as lenient as possible, saying Marin had thought he had done the right thing by staying overnight at a friend's house.
