The most dangerous thing you can do in Tbilisi is cross the street. Pedestrians have only nominal rights and you can expect Georgian drivers to blow through the crosswalk, horn blaring, foot on the gas, even when you have the green walk light. I have personally witnessed four pedestrians hit by cars in the four months or so I’ve lived in Tbilisi. 90 people died and 3,834 were injured as a result of road accidents in Tbilisi in 2015. Most were pedestrians.
Getting around Tbilisi
Tbilisi has excellent public transportation and it is very inexpensive. There are buses, the subway, and the ubiquitous mashrutkas. All of them charge about 25 cents.
The best and most convenient way to pay is to purchase a metro card at the window at the entrance to any subway station. The cards cost 3 lari and you can load them with as many lari as you like. I keep two cards with me and put about 20 lari on each so that when one runs out, I can easily switch and then reload the other one the next time I think about it. You can pay for any subway, bus or mashrutka with these cards and you don’t have to worry about having small change with you. To avoid embarrassment, do either keep a spare card charged or remember to keep your card topped up. It will take you a long time to go through 20 lari though.
