I can't find any relevant Azerbaijani rules of the road, but on the assumption that they follow the general principles as the UK -
Both vehicles enter the four-laned one-way road to the right, travelling within their own clearly marked lanes so there is no reason for them to give way (called "yield" in some places) to one another, or anyone else, unless they intent to change lane.
The UK's Highway Code includes the following:
Rule 131
Lane dividers. These are short, broken white lines which are used on wide carriageways to divide them into lanes. You should keep between them.
Rule 133
If you need to change lane, first use your mirrors and if necessary take a quick sideways glance to make sure you will not force another road user to change course or speed. When it is safe to do so, signal to indicate your intentions to other road users and when clear, move over.
Rule 143
One-way streets ... Choose the correct lane for your exit as soon as you can. Do not change lanes suddenly ...
