The United States Virgin Islands 🇻🇮, formerly Danish, apparently violate international law by driving on the left side of the road, in spite of being claimed by the right-driving United States. International legal conventions often expect all sovereign states to have the same driving direction throughout their respective territories, yet numerous additional examples may also be identified, such as Canada remaining a Commonwealth realm yet being a right-driving sovereign state. The Commonwealth realms are, however, quite different, and are typically regarded as sovereign entities, so Canada is not necessarily entitled to be left-driving according to international law even in spite of the British Head of State serving Canada (Australia and New Zealand, however, each drive on the left as with the British).
Prior to being claimed by the United States, much of the southern Virgin Islands had been claimed by Denmark 🇩🇰, and Danish place names remain intact, particularly on the largest (and southernmost) of the major islands, Saint Croix. Following the American acquisition of the Danish Virgin Islands (at the time known as the Danish West Indies), the Virgin Islands of the United States would claim more territory by area than the British Virgin Islands, and the American side now contains a significantly larger population than the British side as well.
