Anti-drink driving adverts are to be inserted into computer games amid concern at the number of youngsters who consume alcohol before driving.
Police said they had caught almost 150 people under the age of 25 in their annual festive drink driving blitz.
The Scottish Government is to spend £10,000 on adverts on the virtual billboards within Xbox 360 games.
Campaigners said it was vital to look beyond conventional methods of communicating with young people.
The adverts will be seen by Scottish Xbox 360 gamers playing the online versions of titles including Need for Speed: Carbon, Project Gotham Racing 4 and Pro Evolution Soccer 2008.
If the trial is successful, the same technology could be used to deliver a wide range of road safety messages.
