Air travel is the best means of internal transport but services are often overbooked and even confirmation does not always ensure a seat. Travellers are advised to arrive at the airport well before the minimum check-in time in order to obtain confirmed seats. Schedule changes and flight cancellations with no advance warning are also likely hazards. The only railway link runs between Barquisimeto and Puerto Cabello, with four trains daily but no air-conditioning. There are plans for a considerable extension to the rail network.
Traffic drives on the right.
International Driving Permits are also valid. These are operated by minibus companies and tend to serve as the main form of public transport in Caracas and major cities. Fares charged are in general similar to those on the buses, although they are higher during the evenings and at weekends. Taxis in Caracas are metered but the fare can nonetheless be negotiated with the driver. Taxi fares double after 2000.
