The TFR that follows federal convoys nationwide — and doesn't appear on B4UFLY, LAANC, or any standard flight-planning app.

FDC 6/4375 creates a moving TFR that does not appear on B4UFLY, LAANC, or AirMap. You cannot pre-check it the way you would a stadium TFR.
Any DoD, DOE, DOJ, or DHS ground vehicle or convoy triggers a 3,000 ft lateral / 1,000 ft vertical no-fly bubble that moves with it in real time.
Accidental violations are treated the same as intentional ones. Penalties include up to $75,000 in fines, certificate revocation, and criminal prosecution.
Flying at the standard 400 ft AGL ceiling puts you automatically within the 1,000 ft vertical standoff zone if a federal asset is anywhere nearby.
Before every flight, operators must visually scan for unmarked federal vehicles, check local news for federal activity, and document airspace clearance with a screenshot.

Criminal exposure: Violations may be prosecuted as federal crimes. Under FAA Bulletin 2026-1, the burden of proof is shifted — operators are presumed to have known about the restriction. Federal agents are authorized to intercept, seize, or destroy drones in violation.
