Travel is enlightening — but also befuddling. Having just returned from vacation, I’m reliving my adventures by examining signs I spotted during this trip and others. I find myself more confused than ever. Here’s a sign posted on the window of a school in Venice:

Three lines are simple to decode: They teach English, French, and German. But what’s Inglese Postcoloniale? My translation app says “Postcolonial English.” Okay, which colony are we talking about? America after the Revolutionary War? Britain after the Empire morphed into the Commonwealth? A variety of English spoken in former Italian colonies?

Next is a sign my family spotted in Tokyo:

Does the collision occur only when the pedestrian is oncoming, or is an outgoing collision also possible?

Judging from this sign, pedestrians in London should certainly proceed with caution:

I’m all for Road Safety in London (and everywhere else), but killing pedestrians For your own Safety seems counterproductive.

Amid the confusion, I did find one perfectly clear sign:

Bravo, Madrid! Bravo, hotel owner! Even the most jet-lagged travelers, assuming they speak English, can understand this message. Would that all our communications were so easily decoded!

No decoding needed for this message: I wish you happy travels, on the road and in your dreams.
