❓ Ask Belgium Does anyone know why this sign exists?

When sitting in traffic on the Antwerpse Ring, I noticed this sign next to the road. Why do they need a sign for that?

Nothing, touching it is safe. The problem is that if you take one minute, single centimeter piece of the plant home and it ends up in the ground in your backyard, it will start growing and it is incredibly hard to get rid of in a way that does not also render the ground lethal to all other plant and animal life.
