What does the following road sign signify?

- A place in which taxi-passenger loading and unloading is prohibited.

- A place in which the loading and unloading of public vehicle passengers is permitted, without waiting.
- A place for loading and unloading, as well as for waiting, for taxi passengers.
Why this is the answer
The correct answer in the official bank: A place in which taxi-passenger loading and unloading is permitted, without waiting.
The sign combines the taxi symbol with a red-bordered blue circle crossed by a single diagonal stripe, which prohibits parking. So a taxi may stop here only for as long as it takes to pick up or drop off passengers, and may not stand and wait for them. The place is for taxis only, not for every public vehicle.
