March 17,1939 brought a revolution on Czech roads: the commander of the
German occupation forces ordered a change-over to a right-hand traffic
system with almost immediate effect. Although the change had been in the
pipeline for years its immediate enforcement was not easy. Moreover, Prague
was given a 9-day reprieve, creating a schizophrenic situation where
drivers in the capital still drove on the left, but elsewhere around the
country traffic was already moving on the right.
