The Scottish Executive is determined to tackle drink-driving

The number of offences of drink-driving or failing to give a breath test went up from 750 last year to 768.

And the number of people caught driving under the influence of drugs almost doubled from 21 to 40.

Tayside Chief Constable John Vine blamed a "hard core of persistent offenders".

The Don't Risk It campaign ran from 5 December, 2005, until 2 January, 2006. It warned motorists of the risks of losing their licences.

These figures are very disappointing. Driving while under the influence of drink or drugs damages lives Tavish Scott Transport Minister

Mr Vine, of the Association of Chief Police Officers in Scotland (Acpos), which ran the campaign, said: "A hard core of persistent offenders are still drinking and driving.

"The festive campaign is over but the communities of Scotland want these people targeted and arrested. Scotland's police will continue to work hard to do this."

In the final week of the campaign, 148 drivers were caught drink-driving, or refusing to give a breath test, while five were stopped for drug-driving, compared to 178 and nine for last year.

Previous bans

They included a 50-year-old man who was stopped in Fife during week three for driving while unfit - and was caught again during week four.

A number of people were also caught while subject to previous bans.

In addition, almost 200 telephone calls were received by Crimestoppers Scotland from people reporting potentially impaired drivers.

Mr Scott said: "These figures are very disappointing. Driving while under the influence of drink or drugs damages lives.
