On average, the formal indicator of compliance with the requirements of the legislation in the transitional period of language quotas among all TV channels is 98%.

In Ukraine, the national regulator checks the TV channels and radio stations, as well as publications in online media and print media.

At the same time, Ukrainian law permits not to duplicate films made in Soviet times into the Ukrainian language. However, it requires that, when showing (not prohibited) films, Ukrainian-language captions should appear on the screen.
If the channel ignores the requirements of the Ukrainian legislation, then it is expected to be fined in the amount of 5% license fee or (in case of repeated violations) withdrawal of the license.
