Generally, the IID sends a signal to a monitoring company which indicates you had alcohol in your breath at the time you started the car. Once the monitoring company receives the signal, the company will send a message to your Probation Officer and possibly the Erie County District Attorneys Office. It is possible that your probation officer will not violate you if you have a very good explanation, but the most likely scenario is that a violation of probation charge will be filed against you.
In New York State, a Violation of Probation is a Class E felony and generally District Attorneys do not plead it down.
