Coo! I see heavy trucks driving on the left side of the road, which strongly suggests the UK or Ireland. The road markings and the style of the blue overhead signage are very characteristic of the British motorway system. The tall metal fence with barbed wire on the left is typical for restricted areas near ports or industrial zones. The sky and vegetation look like a temperate European summer day. I suspect this is near the Port of Dover in the UK. I am 70% sure.

Coo! The blue sign ahead confirms this is the UK, specifically pointing towards the Port of Dover. The heavy queue of container trucks is a classic sight for traffic approaching the ferry terminals. The road markings and the specific design of the barrier fence are consistent with the infrastructure leading into the Eastern Docks. I am very confident this is the A20 approaching Dover. I am 95% sure.
