LAW states registration not required

[allodial]

Thank you allodial.
This reminds me: I recall you stated previously somewhere that you use no DL.
Does the DOT not require a DL for a "vehicle" for which they issue a number?
Or is the DOT a different jurisdiction altogether?

AFAIK State DMVs are subject to US Department of Transportation regulations, etc. US Department of Transportation is a superior venue to the State DMV. Totally different jurisdiction and venue. If you are not commercial, private, not for hire I am unaware of any driver license requirement.

The USDOT # is not necessarily particular for any particular vehicle unless perhaps its for a vehicle registrant. Its comprehensive for an entire organization. 'Vehicle registration' is also available. It is possible, however, to use the VIN for the legal name.
