I guess I could have figured it out by reasoning from first principles. But I'll admit my ignorance, and that I did not know -- until this morning -- that the police can conduct warrantless seizures/stops of commercial trucks for with no probable cause (or even reasonable suspicion) whatsoever.
But apparently that's the case.
I understand the reasoning. Just add this to the list of areas (border searches, aerial surveillance, etc.) in which you are subject to being searched and/or seized for any, or no, reason.
