Ukrainian cities are not dangerous, though a bit more precaution is required.Common tricks include impersonating a police officer. In doubt ask an officer or tell him you're not following him. The first thing they try is to get you out of the tourists places in to areas where they can 'acquire' a fine.Openly robbing you or pick-pocketing happens less as the risks are bigger.

It is essential to learn some Ukrainian before visiting, or at the very least, learn the Cyrillic alphabet. Everyone can also read, speak and write in Russian and aren't so prickly about it, although they'd apreciate that you learn a few basic phrases in Ukrainian as well. Learn the Cyrillic alphabet both the Russian and Ukrainian versions way in advance until you can write words with perfection, as many do not know the Latin alphabet. German and, especially, Polish as Lvov used to part of Poland is spoken well among people with mature memories of the interwar era.
People selling you tickets at the train station will most likely not speak anything other than Ukrainian or Russian and may have no patience nor sympathy for you. Neither will the people waiting behind you in line. If you speak Polish then surviving in Lviv shouldn't be a problem, as many people understand it since it's quite close to Ukrainian. Some sales people will not know the Latin alphabet, so make sure to carry a small note with your name written in Cyrillic! Queues in Ukraine tend to be a chaotic mess, especially at stations. Assert your place with an elbow and mean stare, because everyone else will, including the fifteen babushki pushing you to the side. Make sure you get in the line for foreigners when you want to buy train tickets. No, the cashier will NOT speak English, but if you know the details of the train you want, just write them down! But if you go to a different line they'll just tell you to go to the foreigner's line, and then you will have wasted a lot of time waiting for nothing.
