The number of Scots convicted of drink-driving has plunged by one-third in the past five years.

The new figures were released on Sunday, as a debate continues on Scottish Government plans to lower the drink-drive limit.

Justice Secretary Kenny MacAskill said 5348 people were convicted in 2010-11, compared with 8071 in 2006-07.

Ministers are set to bring forward proposals to lower the limit from 80mg of alcohol per 100ml of blood to 50mg - bringing Scotland into line with most of Europe.

The Scottish Government figures were revealed in a parliamentary answer to SNP MSP Stewart Maxwell. He said: "These are positive statistics and the trend is plain for all to see - fewer people are drink or drug-driving.

"People are taking on the message that it is completely unacceptable to drive whilst under the influence of alcohol or drugs.

"It is still concerning that a high number of people have still opted to get behind the wheel whilst under the influence, posing a danger to other innocent road users. But these figures are testament to the hard work of our police officers who are helping make our roads safer by taking a tough stance on drink-drug drivers."

Drink-driving is thought to be responsible for around 40 deaths and 170 serious injuries on Scotland's roads each year.
