The vehicles are driving on the left side of the road, which strongly suggests the United Kingdom or Ireland. The road markings are white, and there is a high concrete barrier covered in graffiti separating the carriageways. The tall lighting mast and the general landscape are typical of a major motorway in the UK. I suspect this is somewhere in England, possibly near London. I am moderately sure.

The vehicles are driving on the right side of the road, which contradicts my initial UK assessment. The blue sign with a white arrow is typical of European motorway signage. The graffiti on the concrete barriers and the bare trees suggest a temperate climate in Western Europe. Given the road layout and the style of the infrastructure, this looks like a motorway in Belgium or France. I am fairly confident this is in the Brussels region.
