This includes attempts to ascertain information concerning their welfare and proper treatment under Cuban law. U.S. citizens whom Cuba may consider to be Cuban nationals are required by Cuban law to enter and depart Cuba using Cuban passports. In Cuba, traffic moves on the right. A national highway in fair condition runs the length of the island. In general, roads are poorly maintained in all parts of the country.
Some dirt roads become impassable during the rainy season.
Few roads or city streets are lighted, so night driving is not advised. Most Cuban cars are old and in poor repair, therefore, drivers should exercise extreme care. The abundance of bicycles, pedestrians, and occasional wandering farm animals on Cuban roads are additional reasons for driving defensively. Although licensed travelers can travel between the U.S. and Cuba aboard charter flights, there is no direct commercial air service linking the two countries. Serious concerns about the operation of the Cuban flag carrier, Cubana de Aviacion, particularly regarding its safety standards and maintenance regime, have caused the U.S. Interests Section to prohibit its personnel from domestic and international travel on Cubana de Aviacion.
