The driving side is on the left, which is common in Southern Africa. The road markings include yellow lines on the shoulder, a characteristic feature of South African highways. The landscape, vegetation, and high-mast lighting are very typical of the Gauteng province region. I suspect this is near Johannesburg or Pretoria, South Africa. I am fairly confident in this assessment.

The high-mast lighting and the specific style of the yellow road markings confirm this is definitely South Africa. The sign on the pole mentions "Security Estate," which is very common in the suburban sprawl of Gauteng. The landscape and the general highway infrastructure strongly point towards the R21 or a similar major route between Johannesburg and Pretoria. I am now quite certain of the general location.
