I took my driving test in 1992. Since then no accidents -- touch wood! I somehow imagined I knew traffic signs. Until Budapest, that is. Here is a poser for you: what on earth do these traffic signs mean?
The first one (vertical photo) apparently says: No junk car shall be anchored, even upside down, especially those manufactured before WWII. Junk yard is a 100 meters upstream, if you can make it.
The lower one is even more forward-looking: No burning automobiles are welcome. Come to think of it, NO automobiles are welcome.
