The memo says nothing of requireing a level 2 inspection (where they would look at such things) but may be required at thier discression if you want to DOT Certify it. But let me inquire a bit further. Are you attempting to title it w/ a full size license plate and primary on-road use? If so, you may end up in that boat. I havent heard of anyone in here getting this accomplished in AZ to date. The MVD gave me these options when i went in... I have paraphrased and hope i represented this info correctly... The AZ memo provides direction to MVD employees for three types of Mini-truck operation (in this order in the memo) 1. Off road only (you get a small ATV license plate with the "R" registration catagory) (you CANNOT lawfuly use this method to drive on AZ streets) (This requires level 1 inspection and does NOT require DOT,EPA stuff) 2. On-highway use (You get a normal vehicle license plate) (This option MAY require a level 2 inspection and DOES require DOT,EPA stuff) (Requires YOU certify on form #96-0371 that you have modified your mini-truck in all ways needed to be DOT certified, which is all the junk you are talking about and way more than you probably want to know about) (which will most likly include the engine certification that is currently underway) 3. occational on-highway use (You get a small ATV license plate with the "H" Registration catagory) (requiring you get a normal registration sticker) (This requires level 1 inspection and does NOT require DOT,EPA stuff) Option 3 allows you to lawfully use your mini-truck on "some" AZ public streets. But still call it an ATV to which DOT does not apply.. The exact laws on the road use resitrictions escape me at the moment but from memory all roads w/ 35mph or less and no interstate driving.
