Police have reiterated an appeal to the public not to drink and drive – with 12 motorists already having been charged with alleged offences this month.
Eight men and four women from across the Highlands and Islands will be the subject of reports to the Procurator Fiscal in relation to drink-driving offences.
Five of these incidents occurred last weekend.
Road policing Sergeant Donnie Mackinnon said: "Time and again we have warned people that drinking and driving is dangerous and will not to be tolerated so it is disappointing that we continue to stop drivers who are over the limit.
"Anyone getting behind the wheel under the influence of alcohol not only runs the risk of gaining a criminal record and losing their licence – they also put themselves and other completely innocent road users in danger.
"Over the summer there may be the temptation to have a drink and then drive home. Our message is simple – there is no safe limit. If you need to drive then it is best not to drink at all.
"If you decide to have a drink then make sure you plan your journey home.
"The safety of road users is a priority for us and we will continue to take action against drink drivers."
Last month, police highlighted the dangers of speeding, not wearing a seatbelt and using a mobile phone while driving.
It followed a number of offences detected during April – which included a dedicated operation across Scotland targeting all three offences.
During the month in the Highlands and Islands area, 33 drivers were detected in relation to seatbelt offences and 34 were detected using a mobile phone while driving. These represent a rise from 23 and 27 respectively in the same period in 2017.
A total of 493 drivers were detected in connection with speeding offences in April – a rise from 412 in the same period last year.
Road policing Sergeant Gus Murray said at the time: "All three of these offences are among the main causes of fatal and serious road traffic collisions on the roads of the Highlands and across Scotland.
"It is extremely disappointing that this significant minority of drivers still believe they can take the law into their own hands, putting their own lives and the lives of other innocent road users at risk.
"Drivers need to take responsibility for their actions behind the wheel.
"These figures show that a number of motorists are not heeding the dangers."
