The law regarding under 21 carry is
ARS 13-3102.B.3 - I recommend reading it. Might even want to print it out and carry it with you.
Vehicle carry is in ARS 13-3102.B.3(e):
"A case, holster, scabbard, pack or luggage that is carried within a means of transportation or within a storage compartment, map pocket, trunk or glove compartment of a means of transportation."
Keep in mind that for the last 16 years, there is a court interpretation of the above language, when it was in another section of the law, that said unless the gun was holstered or cased and in one of the magic places (glove compartment, etc.) that "within a means of transportation" meant the gun must be visible from outside the vehicle - something that is impossible with a gun worn in a holster. Cops have been using that court interpretation to arrest people for 16 years. Now that the law has changed, that doesn't mean they will not try to hang that court ruling on this new section of the law.
My recommendation is that if you are under 21 and carrying a gun in a car that you put it in a case or holster (not in a case or holster is a violation of the law) and place it in one of the magic spots (glove compartment, etc.).

I’m not an Arizonan, but I am very close to the AZ border and travel there frequently, so I took interest in this question and have taken a look at the AZ statute you refer to. Here is what it says (I’ll bold the words/phrases that appear important to me):
A. A person commits misconduct involving weapons by knowingly:
2.
Carrying a deadly weapon except a pocket knife
concealed on his person or concealed within his immediate control
in or on a means of transportation if the person is under twenty-one years of age.
B. Subsection A, paragraph 2 of this section shall not apply to:
3. A firearm that is carried in:
(e) A case, holster, scabbard, pack or luggage that is carried within a means of transportation or within a storage compartment, map pocket, trunk or glove compartment of a means of transportation.
Looks to me... my opinion... that OPEN CARRY
in a car/truck or
on a motorcycle/scooter doesn't violate this law. CONCEALED CARRY would violate the law IF one is under 21, otherwise even concealed carry is within the law.
Further, the law (whatever it is) doesn't apply to a firearm that one has cased, holstered, scabbarded, or otherwise packaged if one has it in some type of "storage compartment" within the vehicle, e.g. trunk or glove compartment of a car or perhaps saddle bags of a motorcycle.
So, if on the day before my 21st birthday (still only 20 at that point) I ride my motorcycle into AZ and I have a .45 holstered and visible on my hip (OPEN CARRY ON MY PERSON), I'm within the law. If, while I'm there I decide to stow my holstered .45 in my saddlebags and ride around like that, I'm still within the law because then the law (whatever it is) doesn't apply. The next day I'm 21 years old and I decide to CONCEAL CARRY ON MY PERSON under the same circumstances as before and I'm within the law also. Also, now that I'm 21 I can do either in or on my means of transportation ... OPEN CARRY or CONCEAL CARRY at my discretion.
Is there some other interpretation I'm not grasping here?
