Any Ideas?

I walk by this sign just about everyday since it is on my way back from the central market and have no clue what it means. I've been going with don't hold hands with people wearing strange hats and it's worked for me so far. Come to think of it, the hat does look a little like Freddy Krueger's from Nightmare on Elm Street.

Slovakia

So this weekend we entered Slovakia and apparently Hungary is not the only one with confusing signs. Looking at it now I can see it's speed limits for cars and trucks in and out of cities and  I guess the bottom two are for big roads in and out of cities but when you're on the move it is an awful lot of information to take in. I think the easiest thing is to just do what everyone else is doing!

Anyone else confused?

Hungarian is only spoken by about 10 million people world wide and there is probably a good reason for that, it's really difficult to learn.  Knowing only very few basics I need to rely on signs a lot. But signs like the one below could use a little clarification.  Dog or no dog? Fire or no Fire?
