The rock face shows distinct, weathered geological features often found in tropical or subtropical mountainous regions. The vegetation clinging to the top suggests a humid climate. There is a faint, possibly hand-painted or weathered script on the rock face that looks like it could be Devanagari or a similar script. Given the road conditions and the rock formation, this feels like a hilly area in India. I suspect this is in the Western Ghats or a similar mountainous region in India. I am moderately sure.

The road markings show a solid white line on the side, consistent with driving on the left in India. The rugged rock face and the specific type of utility pole are very characteristic of the winding roads in the Nilgiri or Western Ghats mountain ranges. The lush, humid vegetation confirms a tropical highland environment. I am fairly confident this is in the state of Kerala or Tamil Nadu.
