If you are charged with a DWI in New Jersey, you will face some serious consequences. One consequence you may face is an ignition interlock device. These devices are installed when an individual faces certain DWI charges. You will have to utilize the ignition interlock device for a certain amount of time depending on a number of different factors. Some of these factors include your BAC, your previous charges, and so on. Read on to learn more about ignition interlock devices in New Jersey.

What is an Ignition Interlock Device?

An ignition interlock device is a device that is installed into your car. It requires individuals to take a breathalyzer test each time they wish to start their car. If the ignition interlock device reads a level of 0.05% BAC or higher, the car will not start. In some cases, in order to ensure that someone else did not blow into the device, there will be required breaths while driving. If an individual does not own a car, the device must be installed on any car that they may operate. Individuals who must participate in this program are required to pay for the installation and other expenses related to the device, making a DWI even more expensive.

What Do I Need to Know About Ignition Interlock Devices?

The New Jersey Motor Vehicle Commission requires that the ignition interlock device meets the following criteria:

  • The device must be installed at a service center designated by the Motor Vehicle Commission
  • The device must be able to detect a blood alcohol content of 0.05 percent
  • The device must be serviced every 67 days
  • The device requires a label warning of civil liability or prosecution for anyone who tampers with the device
