What is the meaning of the following traffic sign?

- Taxi stand in airports.
- Designated waiting place for a taxi service route.
- Designated waiting place for taxis.
- Correct answer: Place for loading and unloading of taxi passengers only. Waiting for passengers is prohibited.
Why this is the answer
The correct answer in the official bank: Place for loading and unloading of taxi passengers only. Waiting for passengers is prohibited.
The taxi symbol shows that the place is intended for taxis, and the blue circle with the red border and diagonal stripe adds a parking prohibition. So a taxi may stop here only for the time needed to load and unload passengers. It may not stand and wait for passengers.
