According to the traffic signs appearing in the picture, the road that turns to the left is:

- A restricted non-urban road.
- A freeway.
- Correct answer: A inter-urban road.
- Not a main road.
Why this is the answer
The correct answer in the official bank: A inter-urban road.
On direction signs, a green background marks a non-urban road and a blue background marks an urban road. The sign pointing left is green and shows a road number, so the road turning left is a main inter-urban road.
