Men at work, 90 km/h speed limit roadsign

That's a building?

No, just a roadsign lying down.

Just wondering if it was a Building because it's categorized as one.

In some case rather than have a high level category for everything or put everything in a misc category we have to apply the best that we have.

Sometimes a sub category gets used as an adjective / modifier. We are fairly loose with the categories so don't expect perfect fits all the time.

Just for the records: it's 'Wassenaar' without the 'h'. Now you've written in dutch 'washed hair'. It's no big thing!

I've thinking that the "Transportation - Automotive" category, was the good category for road related things. When the men at work build roads, roads are building. Am I wrong ?
And sorry for the extra H. All my post for this town have a shampoo name.
