How’s this for ‘sign of the week’?
Yes, you have seen correct. It is a sign not just for bike crossing, but also toad crossing. In Dutch, the word for toads is padden and the word for path can be trek. Hence, Paddentrek, toad crossing.
This has cracked me up for the almost 4 years I have been in Belgium. And these toads supposedly cross the road from 7pm to 7am. I’ve not yet personally seen any flock or herd or school or whatever of toads crossing the street yet. I do hope so one day. If I have my camera with me, I’ll take a pick and post it up here.
This has to win some kind of sign-of-the-year award.
The Prodigal Thought 
I’m impressed that Belgian toads are able to read the sign so they know where and when to cross.
It’s more for the people to see it and look out for any crossing toads.
Scott, I think they call a group of toads a “knot”, at least in English. Now, I’ve “knot” seen any such groups myself, either…
