The rail system is underdeveloped but most major cities are connected to the network. Frequent ferry services connect the mainland with the larger islands, and boats operate on Lake Peipus and the Emaj gi River. Estonia has a high density of roads although there are few major highways. Signs are not illuminated and fairly small, so driving at night is best avoided. Car headlights must be used 24 hours a day.
Payment is in local currency or by credit card.
Traffic drives on the right. There is a wide network covering most of the country including express services. Prices are very low and buses are still the most important means of transport. Private taxis must display the name of the company and their number on the roof. Fares should be agreed upon beforehand.
