More than 500 drivers in Northern Ireland are being prosecuted for drink-driving offences following a police crackdown over Christmas and New Year.
A total of 552 people were found drink-driving between November 22nd and January 2nd - a rise of 23 on the figure during the same period in 2004/2005.
More than 3,700 motorists were screened over the period this year. Men accounted for 495 of the 552 who tested positive.
Police also confirmed that 29 drivers were three times the alcohol limit, two were four times the limit, and 45 people tested positive the morning after - between 6am and 11am.
Some motorists were unfit to drive, and others were unable or refused to give a sample.
Police have mounted Operation Viper in rural and urban areas in Northern Ireland over the past year to identify a range of motoring offences.
