There are two classes of trains, primarily distinguished by the comfort of the seats. Children under five years of age travel free and children from five to nine years of age pay half fare. Traffic drives on the left. Travellers attempting to drive around Georgia independently should be aware that it is difficult to buy fuel without highly specialised local knowledge and that an adequate supply of fuel should be obtained in Tbilisi beforehand. Also, reliable road maps or signposts do not exist.
Buses provide a reliable if uncomfortable service between towns within the republic.
An International Driving Permit is required. Tbilisi is served by buses, trolleybuses, cable cars and a small underground system. It is common practice to flag down official taxis, but fares should always be negotiated in advance, bearing in mind the likelihood that rates set for foreigners will be unreasonably high. In view of the rising crime rate, foreigners should take precautions before getting into a car, and it is generally safer to use officially marked taxis which should not be shared with strangers. It is inadvisable to take a ride if there is already more than one person in the car.
