Arizona law (A.R.S. § 8-323) provides for the following penalties for a minor who purchases, possesses, or consumes, spirituous liquor:

1. Probation.

2. A juvenile court hearing.

3. Driving privileges suspended for 180 days.

4. Attendance at a counseling or education program.

5. A fine of up to $500.00.

6. Community service work.

7. If truancy is involved, a whole host of programs with parents.

8. With a prior record that indicates delinquency, a whole other host of headaches.

9. A stern talking to by the judge. (Don't laugh, an angry judge is a very scary thing.)

It appears that a judge can impose any combination of these things that she thinks is a good idea. Laws in other states are probably similar. The law about juveniles is never cut and dried.
