The state of Arizona classes probation violation as a serious offence. An individual becomes in violation of the terms of their probation if the stipulations set in their probation meeting are violated. This can include requirements such as drug screening, or paying fees of fines, or if a new crime is committed.
The sentence you will face for this offence is dependant of the crime you originally committed, unless of course you are arrested on a new charge. Most commonly your probation will be revoked, and you will be required to serve the custodial sentence connected to your offence.
If you are serving more than one probationary term, then you may be sentenced to jail or prison time to be served consecutively for each offence you have been charged with.
