Road policing officers in the Highland and Islands are reminding road users of the dangers and consequences of driving after drinking or taking drugs ahead of the New Year's celebrations.
Local officers have been supporting a national campaign, with high visibility patrols across the region throughout the festive period.
The campaign aims to reduce the number of people drinking and driving, while detecting those who do.
Mobile and static patrols are continuing across the Highlands and Islands. Officers will continue to be on the roads this weekend to watch for anyone suspected of being over the limit.
Sergeant Gregor Hay of the Road Policing Unit, based in Dingwall, said: "Despite the varied and well-publicised consequences of driving under the influence of drugs or alcohol, we still catch drivers who ignore the risks and get behind the wheel.
"This weekend many people will be attending parties and events to celebrate Hogmanay and New Year's Day.
"Our advice would be to make travel plans in advance to so that the temptation to drive under the influence is removed. If you are planning to drive then it is best not to consume any alcohol at all - there is no safe limit.
"I would also urge people to think about any journeys they have to make the following day, taking into account the period of time alcohol remains in a person's system the morning after.
"Driving under the influence is a selfish act which puts all other innocent road users at risk of injury or worse.
"We will not tolerate it and anyone caught over the limit will be arrested and then runs the risk of losing their licence and their vehicle.
"Please enjoy yourself this weekend but don't let alcohol or drugs ruin the start of 2018 for yourself or anyone else."
Anyone with concerns about a suspected drink or drug driver is urged to contact 999 if it is an emergency or 101 to play their part in helping road policing officers keep people safe.
