Is a vehicle a thing? I want to define one as either stationary or in motion.

Yes. A vehicle is a container, a container is a thing. Look at the “Kinds/Chart” page in the Index tab.

OK, thanks, but as a thing, I can write the “stationary/in motion” condition, right?

You mean something like this?

A vehicle can be either stationary or in motion.

Almost any object is a thing, the main exceptions being rooms and directions. And this would work even if it weren’t a kind of thing.
