Operating authority and DOT numbers do not always transfer
Movers run on federal or state operating authority, and that authority is tied to the seller, not the trucks. Interstate movers need active FMCSA authority and a USDOT number; intrastate movers face state-specific licensing. In an asset sale this authority frequently has to be re-applied for rather than handed over, which can create a gap in your ability to operate legally. Confirm exactly what licenses exist, whether they convey, and how long a fresh application would take before you close.
