More than 600 people under the influence of alcohol or drugs were detected during last year’s festive period, Police Scotland has said.
The force launched its annual festive drink and drug driving campaign on Thursday, which will run until January 2.
Officers will be targeting those driving under the influence across the country, as well as speaking to motorists and carrying out enforcement.
The campaign aims to highlight the dangers of driving after consuming alcohol and drugs.
Chief superintendent Louise Blakelock, head of road policing, said: “As we all look forward to celebrating this festive season with friends and family, we are urging motorists to help us keep the roads safe for everyone.
“We continue to see the minority of motorists put themselves and others at considerable risk by driving after consuming alcohol or drugs, despite repeated warnings about the dangers.”
She added: “Driving under the influence reduces your ability to react to what is happening on the road and sadly continues to be a factor in fatal and serious injury collisions.
“As well as a breath test, officers can also test salvia for the presence of drugs at the roadside.
“Our message is for you to be safe on the roads and not drive after consuming alcohol or drugs, so we can all enjoy a safe festive season.”
