A total of six police forces have joined together to target motoring criminals on the southern Scotland and northern England border.
As well as searching vehicles, other supporting agencies, such as the Benefits Agency and the Motor Insurance Bureau, will help identify people responsible for other crimes like metal theft and drug trafficking.
"The majority of motorists who utilise the road network between Scotland and England need not worry themselves with our presence over the next couple of days.
"However, a small number of people use these arterial routes to commit crimes North and South of the border and all the police forces are working closely together to bring these individuals to justice.
"As well as deterring and detecting crime, police will use this opportunity to gather intelligence on criminals who regularly move between both countries."
– Superintendent Denise Mulvaney, Head of Road Policing for Lothian and Borders Police
Morotists are being warned to take care on roads across Dumfries and Galloway due to the heavy rain that has been falling.
Many roads across the region are becoming flooded because of water running off adjacent fields and verges, often carrying stones and gravel with it and motorists are being warned to be aware of standingwater on many roads, and the dangers of driving in such circumstances.
Lights should also be switched on when visibility is poor.At present the A75 road through Dumfries and Galloway is closed at Twynholm because of flooding and diversions are being put on which will take motorists around this closure.
