[Old Professer]

You simply must go back and read post 92; the 28-4804 section clearly states that a person can post a bond to satisfy the financial responsibility law as long as that person has no outstanding judgements against him and he doesn't meet the use restrictions in article 2.

Perhaps you should read all of the sections in article 2.

Click on the link and read it carefully, but in any case it isn't worth starting a war over.

Well 4804 is about abandoned vehicles, I'm not sure which section you're refering to. I've read all of article 2 (4031 - 4037) and all it does is describe what the financial requirement is. 4007 is still the one that applies directly to self insurance, and section A is pretty clear (my emphasis, obviously):
A person in whose name more than twenty-five motor vehicles are registered or who is required to comply with the financial responsibility requirements prescribed in article 2 of this chapter may qualify as a self-insurer by obtaining a certificate of self-insurance issued by the director as provided in this section.

There are only two groups who can self insure in AZ: people with fleets and the list under article 2 (chauffeur, hazardous material, shipping, all corporate type stuff, non-profit car-pool is specifically exempted).

If that's not clear enough we go to section D of 4007:
D. A person who is required to comply with the financial responsibility requirements prescribed in article 2 of this chapter may apply for partial self-insurance to cover any portion of the financial responsibility requirements.

Again the general public is left out. There's nothing in there saying that any old person can do it. For partial it's just people required by article 2, not even the 25 vehicle people can do that. In both cases (full self-insurance or partial) we have exclusive lists that do not include the average shmo on the street. And there's no indication that the average shmo has this option.
