Claim: Belize, the only continental Central American country which is a Commonwealth realm, having Queen Elizabeth as its monarch, did not have license playes with its name on them until 1973.
Evidence: The 1973 license plates were the first to have the name Belize on them. Belize (/bəˈliːz/ (listen)), formerly known as British Honduras, is a Caribbean country located on the northeastern coast of Central America. Belize is the only continental Central American country which is a Commonwealth realm, with Queen Elizabeth II as its monarch and head of state, represented by a Governor General (currently, Sir Colville Young).
