Right hand traffic was already introduced in
Slovakia by a decree of the government of "autonomous Slovakia" within Czechoslovakia in late 1938. After the creation of the
Slovak State in March 1939, buses in the capital
Bratislava were adapted, and the last roads in Slovakia switched to the new system in 1940/1941. The areas which are nowadays the southern border regions of Slovakia were subsequently part of Hungary (under the terms of the
First Vienna Award), and did therefore change to right hand traffic as late as 1941, together with the rest of wartime Hungary. ==See also==
