Better late than never.
IRL they're single ones, random example. Although some local authorities tend to forget about foreigners/tourists and they install signs with ukrainian language only. (this does not apply to international routes.)
BTW, the goverment have changed current license plate system. From the 21 of September we have new series for trailers, public transport and taxi plates (yellow ones) and we got new plates for electric vehicles.
1st pic: New trailer series. The old trailer plates series are still valid. 2nd pic: New bus (public transport) series (yellow). 3rd pic: New taxi series (yellow too). NB: Latin script is used ONLY on abovementioned types, for regular plates everything remains the same (12 letters which are common for both alphabets). Here's some examples of real plates if you're interested.
I know, that current SCS plate system doesn't support plates for EVs, but can we have new trailer series in the future updates? New public transport and taxi plates haven't started yet, so I don't ask for them now.
