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

An ignition interlock device is a device that attaches to your vehicle and will likely be required by the court to install if you have been charged with a DWI. It works by requiring individuals to blow into a breathalyzer in order to be able to start your car. If you blow into the device with a blood alcohol concentration above .05%, the car will not start. Additionally, as you are driving you will likely need to provide more breaths to show your sobriety level. If you fail to provide a breath sample when asked to, the device will emit an alarm, forcing you to pull over.

New Jersey takes these devices very seriously and if someone else provides a breath on behalf of you, the driver, harsh penalties can result.

Do I have to install an ignition interlock device?

A first offense DWI with a blood alcohol concentration over .15% may need the installation of an ignition interlock device in your vehicle. It may also be ordered if you refuse to take a breathalyzer test. It is important to note that 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 decision on whether or not that individual will need an ignition interlock device installed is up to the court.

Where can I obtain an ignition interlock device?

Ignition interlock devices can be installed at multiple different locations. Most likely, you will have a local auto-related service shop in your area that can install the ignition interlock device, at your own expense. Usually, these devices will need recalibration as time goes on, and you will have to schedule appointments for it either every 30, 60, or 90 days.

The ignition interlock device is embarrassing, expensive, and a hassle. If you have been charged with a DWI, do not wait to speak with our experienced New Jersey attorneys as soon as you can to learn more about your options.
