The government has launched its Christmas campaign against drinking and driving.

A television commercial was screened on Monday, and will continue running until New Year's Day.

Although drink-drive deaths have fallen dramatically over the past 20 years, 2002 saw an increase of six per cent to 560 fatalities.

Those found guilty of driving or attempting to drive while over the legal alcohol limit face a maximum six-month prison sentence and £5,000 fine, or a driving ban of at least 12 months, increasing to three years if convicted twice within a 10-year period.

"Drink drivers are still killing people," said transport minister David Jamieson.

"Last year, one in six deaths on our roads was drink-drive related. The vast majority of motorists know the dangers and obey the law - but a minority of irresponsible and reckless drivers are ignoring it.

"If you are going out and enjoying yourself over Christmas - don't turn your night into a nightmare - leave the car at home, and if you can't use public transport, designate a non-drinking driver.

"Remember that you could still be over the limit in the morning after a good night out."
