When convicted of a charge of driving while intoxicated or aggravated DWI, you must install an ignition interlock device in your vehicle. A New York judge may order the use of an IID for at least 12 months of a probation sentence.

After a conviction and sentencing, the backside of an individual’s driver’s license will show the requirement for IID use. Failing to comply with a judge’s IID order may result in up to a year in jail.

Discovering a motorist driving without a required IID

As reported by the Suffolk Daily Voice, a law enforcement official can conduct a computerized check on a motorist’s DMV records. When a record reveals that a vehicle requires an IID system, an individual may face arrest and a misdemeanor charge if the car does not have one installed.

If law enforcement discovers that you allowed an IID-required motorist to borrow your vehicle without the court-ordered device installed, you may also face an arrest. Penalties could include incarceration of up to one year.

Using an IID to start a vehicle’s engine and keep it running

The essential purpose of an IID is to detect a motorist’s blood alcohol content level before starting a vehicle. An individual must blow into a device connected to the car’s electrical system. If the system detects an individual’s BAC of 0.025% or more, the engine will not start.

After the vehicle has been moving, the IID randomly requests the driver to blow into the device again. As noted by The New York Times, when a motorist fails a breath retest, the car horn begins honking and the lights start flashing.

You can turn off the car to stop the alarms. In order to restart the vehicle, however, you must first submit a passing breath test.
