Police Scotland will double its presence along the border with England after Nicola Sturgeon announced tighter coronavirus restrictions.
Chief Constable lain Livingstone said “highly visible patrols” on roads will be used to “deter anyone who night be considering breaching the coronavirus travel restrictions”.
The First Minister announced severe lockdown measures for Scotland on Saturday.
They included a “strict travel ban” preventing travel to or from other parts of the UK, which was put in place last month but was due to be removed over the Christmas period.
Some exceptions to the ban are allowed for essential purposes.
In a statement, Mr Livingstone said it would not be “appropriate or proportionate for officers to establish checkpoints or roadblocks to simply enforce travel restrictions”.
But he added: “Today, I have authorised the doubling of our operational presence in the Border areas of Scotland.
“These highly visible patrols will be proactively deployed on our road networks to continue our operational activity to ensure drivers and vehicles are in a fit condition to drive.
“The patrols will also deter anyone who night be considering breaching the coronavirus travel restrictions.”
He said he expects roads to be “quieter than usual over the corning days”.
“We have been clear throughout this public health crisis that your police service is here to support our collective effort to combat coronavirus.
“Though the rules have changed often and, at times, quickly, officers and staff will continue with common sense, empathy and discretion to work with our fellow citizens to help keep everyone safe.
“It is the consent of the public from which policing in Scotland draws its legitimacy. As our communities expect, where officers encounter wilful, persistent or flagrant breaches we will act decisively to enforce the law.”
