What is the purpose of ignition interlock devices in New Jersey?

If you have been charged with a DWI in New Jersey, you will likely be required to install an ignition interlock device on your vehicle. Ignition interlock devices are devices that attach to your car and makes the driver blow into a breathalyzer to read his or her blood alcohol concentration before the car is able to start. If you blow into the device with a blood alcohol concentration above .05%, the car will not start. Also, while you are driving you will likely need to provide more breaths to show your sobriety level. If you decline to provide a breath sample when asked to, the device will emit an alarm, forcing you to pull over.

Do I have to install an ignition interlock device?

In New Jersey, those who were charged with a first offense DWI with a blood alcohol concentration over .15% may need the installation of an ignition interlock device in the vehicle. It may also be required if an individual refused a breathalyzer test. In the state of New Jersey, the device needs to be installed after the driver’s license is returned for a minimum of six months and a maximum of one year.

If the motorist’s blood alcohol concentration is lower than .15%, then the court will have to decide whether or not the individual should merit the installation of an ignition interlock device.

Where can I obtain an ignition interlock device?

There are several different locations that an ignition interlock device can be installed. Typically, local auto-related service shops are equipped for installation. It is important to note that these devices need recalibration either every 30, 60, or 90 days.
