The vehicles are driving on the left side of the road, which is common in Southern Africa. The road markings and the general landscape, including the specific type of vegetation and the wide, open sky, strongly suggest South Africa. The architecture of the road infrastructure and the style of the trucks align with the Gauteng province. I am fairly confident this is in the Johannesburg or Pretoria area.

The road signs are green, which is standard for major highways in South Africa. The vegetation, including the eucalyptus-like trees and dry, grassy embankments, is very characteristic of the Highveld region. The highway design and the surrounding industrial-looking buildings strongly point toward the outskirts of Johannesburg. I am confident this is on a major arterial route near the city.
