What is the driver obliged to do according to the following picture?

- Pull into the “hard shoulder” and slow down.
- Correct answer: Slow down and keep to the right.
- He is not obliged to do anything special.
- Honk and flash his lights.
Why this is the answer
The correct answer in the official bank: Slow down and keep to the right.
In the picture the road bends and the field of vision ahead is limited, so you cannot know what is coming beyond the bend. In such a situation, slow down and keep to the right as far as possible, so there is time to react and a safe gap from a vehicle coming toward you. There is no need to honk or flash your lights, and pulling onto the hard shoulder is not required.
