If you read your state’s constructive and vehicle laws, you will likely find that either:
a trust is not a person
the state’s traffic laws only apply in commerce
private vehicles and conveyances are not regulated
The applicability of those laws hinge on law enforcement perceiving your presence on the road as being commercial in nature, as such to need a driver in the transport of cargo or passengers for compensation. In order to avoid the available charges and citations for similar actions using your automobile, we take the automobile out of their jurisdiction.
Normally, your car would be registered between the state and you. This must change in order for the USDOT tags to work.
First, you must establish a different responsible entity that will own you car. An ideal candidate to do this effectively is your trust. Your trust will be registered with the Federal Motor Carrier Safety Administration (FMCSA). The registration is a contract between the trust and the agency that the trust will abide by the rules of the United States Department of Transportation, which most state traffic and vehicle laws are derived. As a result, your trust is issued a USDOT number to be recognized in commerce. Your trust is now recognized within the context of commerce.
Your trust must own the car. Outright. This is only done at your state’s Division of Motor Vehicles agency or equivalent. You will not re-register the car back to the state.
As with the trust and the FMCSA, registering the car with the state creates a contract between the registrant and the issuing authority (the state) that the registrant will conduct themselves in accordance with the rules that the issuing authority has established, which applies for commercial acts only! If you already have an existing National contract in place that dictates that the owner of the car is not in commerce, why would you enter a state contract that is in direct contravention to the first for the use of the same car?
Now that the car is sufficiently covered, you can now focus on protecting YOU. The best way to do this is by Trademarking Your Strawman.
