St. Thomas is an island in the Caribbean Sea and with the islands of Saint John, Saint Croix, and Water Island a county and constituent district of the United States Virgin Islands (USVI), an unincorporated territory of the United States. Located on the island is the territorial capital and port of Charlotte Amalie. As of the 2010 census, the population of Saint Thomas was 51,634.
The district has a land area of 31.24 square miles. The United States Virgin Islands is the only place under United States jurisdiction where the rule of the road is to drive on the left. This was inherited from what was the then-current Danish practice at the time of the American acquisition in 1917. However, because St. Thomas is a U.S. territory, most cars are imported from the mainland United States and therefore the steering column is located on the left side of the vehicle. The island has many regular taxis from compact size to large vans, as well as open-air, covered trucks called ‘safari cabs’ with bench seats. The latter usually operate only between high-traffic points like the cruise-ship terminals at Havensight and Crown Bay and downtown Charlotte Amalie. Typically, they charge one dollar and are the cheapest way to navigate the islands.
