Saint Thomas is one of the Virgin Islands in the Caribbean Sea and, together with St. John and Water Island, forms a county and constituent district of the United States Virgin Islands, 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 about 48.5% of the US Virgin Islands total. The district has a land area of 31.24 square miles.
The island is serviced by the Cyril E. King Airport.
Passenger and limited car-ferry services to neighboring islands such as Water Island, St. John, St. Croix, and the British Virgin Islands run regularly out of the Red Hook Terminal, Charlotte Amalie, and Crown Bay Marina.
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 “safaris” with bench seats. The latter usually operate only between high-traffic points, e.g., cruise-ship terminals at Havensight and Crown Bay and downtown Charlotte Amalie.
