The driving side is on the right, which is standard for most of Europe. The green anti-dazzle screens on the central barrier are very characteristic of highways in Poland. The red and white chevron sign is also typical for European road infrastructure. The vegetation and clear blue sky suggest a temperate climate during summer. I suspect this is in Poland, likely near a major city like Warsaw.

I am 60% sure.

The green anti-dazzle barriers on the median are extremely common on Polish expressways and motorways. The road markings and the general infrastructure style confirm a Central European setting. Traffic is heavy, and the surrounding dense, lush green trees are consistent with the Polish landscape in summer. I am confident this is a major road in Poland, likely near a large urban center like Warsaw or Kraków.

I am 80% sure.
