Can minors be issued civil traffic violations without parents being contacted in AZ?

Son (13yrs.) received warning from local cop not to ride off-road dirtbike in the area and instructed son to "get home in a civil manner". Parent was not contacted at this encounter. Then approx 20-30 min later son was spotted by same officer riding at 5mph or less on dirt shoulder of road (headed home in "civil manner"). Officer issued 5 citations (28-2532A, 28-3151A, 28-4135A, 28-925A, 28-924A). Parents were never contacted by police and dirtbike was impounded. What are a minors rights in this situation if any?
