What is an Interlock Device?

An interlock device is known by many names: ignition interlock device (IID), car breathalyzer, interlock system, to name a few… while the names vary, the function and purpose are the same — to prevent drunk drivers from operating a vehicle while intoxicated.

What is an Ignition Interlock Device?

The first interlock ignition device was invented in the 1970s but didn’t reach the wider market until the 80s. Today, all 50 states have enacted some form of ignition interlock laws that require DUI offenders to install an interlock device on their vehicle in order to be able to keep their driving privileges.

The push for mandatory interlock devices for first-time offenders is becoming stronger each year. Statistics show that the use of interlock devices significantly reduces the chance a convicted DUI offender will drive while intoxicated.

Deaths attributed to DUI/DWI are a serious issue. Organizations like Mothers Against Drunk Driving (MAAD) report that drunk driving is the number one cause of death when it comes to auto accidents. There are approximately 30 deaths attributed to drunk driving every single day in the United States – that’s one every 48 minutes. Ignition interlock devices, and the laws that regulate them, are designed to help reduce these deaths and other injuries.

In New Jersey alone, the statistics clearly show how necessary an ignition interlock program truly is. The New Jersey State Police, the Centers for Disease Control and Prevention (CDC) and Mothers Against Drunk Driving (MADD) regularly publish statistics on DUI/DWI in New Jersey.

  • Driving under the influence was listed as a contributing factor in 118 out of 522 fatal car crashes (22 percent) in New Jersey in 2015.
  • Nearly 80 percent of drunk drivers killed in accidents tested positive for a blood alcohol content (BAC) level of 0.08 percent or higher.
  • Drunk driving fatalities cost New Jersey taxpayers an estimated $992 million every year.
  • According to a CDC study, 1.5 percent of New Jersey drivers report driving after having too much to drink at least once within the past 30 days. This is slightly lower than the national average of 1.9 percent.

While it is common knowledge that repeat offenders are more likely to have an interlock device requirement, the law in New Jersey now dictates mandatory interlock device requirements even for first-time offenders. The goal of this, of course, is to dramatically reduce the number of repeat offenders.

If you have a drunk driving conviction and are now facing an car breathalyzer requirement, chances are you have a lot of questions. At Interlock Device New Jersey we are here to make sure all of your questions are answered and that we can get you back on the road as quickly and painlessly as possible.

What Is An Interlock Device?

An interlock device is a piece of equipment that is installed in a person’s vehicle after they have been convicted of DUI. An ignition interlock device — or IID — works like a breathalyzer and requires the driver of the vehicle to pass a breathalyzer test in order to start the vehicle. The device itself is slightly larger than a cell phone and will periodically require the driver to blow into the device in order to continue operating the vehicle.

How Does An Interlock Device Work?

An interlock device is a car breathalyzer that is hard-wired to a car’s ignition system and requires the driver to provide a breath sample before the car can start. It interrupts the ignition system of the car and won’t allow it to start until a passing test can be provided.

When it’s time to drive the car, the driver will simply blow into the handheld device which is generally located on the dashboard of your car. The Interlock device will then measure the driver’s blood alcohol content. If the BAC is over the limit preset by the ststae, the interlock device will prevent the vehicle from starting.

Commonly, interlock devices will be set up to give “rolling tests.” These tests will take place at random intervals once driving has begun. They are designed to keep the driver from having a sober friend blow into the ignition interlock device when the car is first started. It would also prevent the driver from consuming alcohol once the car is already on the road.

Additionally, the ignition interlock device will record the BAC content each time the driver takes the breath tests. If their blood alcohol content is over the preset limit, this report can be downloaded and then provided to the court if necessary. These reports will also be able to document if the device has been tampered with.

Ignition Interlock Device Laws

Ignition interlock devices are mandated for all persons in New Jersey who have been convicted of driving under the influence or for those who have refused a breath test after being pulled over by police.

Interlock Device Requirement

Interlock device requirements vary greatly based on the details of the offense and if it is a first or subsequent offense.

  • First offense: An ignition interlock device may be required for a conviction with a BAC at or above 0.05% depending on the judge’s decision. Every conviction with a BAC at or above 0.15% in New Jersey will mandate the installation of an ignition interlock device.
  • Second offense: For a second DUI conviction within two years in New Jersey, there is a mandatory license suspension for two years. There is, however, a chance of regaining driving privileges with an ignition interlock device.
  • Third Offense: A third DUI conviction within ten years, or if there are four or more alcohol-related offenses on record, it will cause a license suspension for ten years.

Interlock Device Exemption

When an interlock device is required, there are hardly any situations where an exemption can be made. The primary situation where an exemption may be possible is if the person who was convicted does not own any vehicle and can prove that they will not be operating any vehicle. They would then have a suspended license and would not legally be allowed to drive any car or motorized vehicle until the suspension is over.

Ignition Interlock Device Program

Every state within the US has now adopted some form of an ignition interlock device program. These programs are in place to help reduce drunk driving incidents (primarily for repeat offenders) as well as help those who have had a drunk driving conviction continue with their lives post-conviction. The laws recently passed in New Jersey dictate that first-time offenders will have an interlock device requirement. Studies show that requiring offenders to install an interlock device on their vehicle after being caught driving under the influence significantly reduces the possibility that the offender continues driving under the influence.

Failed Interlock Test Consequences

The first thing that will happen if you fail your ignition interlock device test is that your car will not start for a specified period of time. This is called the “lockout period”. The first lockout period is generally only a few minutes, after which you can then retest. After each failed retest however, the lockout period will last 60 minutes..

Your interlock device will record each interaction, both successful and failed tests, as well as the blood alcohol content level at the time. These recordings can be run as a report and provided to law enforcement or the courts if necessary.

Draeger Interlock Device Benefits

We understand that adjusting your daily routine to include using an interlock device can seem a bit overwhelming, which is why we use the Draeger Interlock Device – a top of the line device that has several important benefits:

  • Speed and convenience of use: Some other ignition interlock devices may take upwards of three minutes to use, Draeger interlock devices are much more efficient. Draeger ignition interlock devices use a very simple blow and suck technique meaning the breath test can take as little as 10 seconds to complete.
  • Discretion is key: Draeger devices are specifically designed to be discreet. About the size of a cell phone, these interlock devices have a sleek design, making them less noticeable to passengers. This means that Draeger interlock devices will blend with the car’s interior, ensuring a clean, seamless look.
  • Safety is of the utmost importance: Many times, rolling retests (additional breath samples taken once the car is already in motion) will be required. It is crucial that these tests don’t distract you from driving or cause you to take your eyes off the road. The Draeger interlock device will beep in order to notify you that a rolling retest is required. You will then have a few minutes to safely stop the vehicle in a place where you can provide the breath test. It is a simple process that allows you to keep the engine running and quickly get back on the road.

Draeger Interlock Device Features

The Draeger Interlock XT is the most advanced unit in the marketplace. The heated electrochemical fuel cell and breath sample pathways provide an extremely reliable and accurate measurement. Some of the features of this specific interlock device model are:

  • Blow Pattern Technology – Other interlock devices require the driver to perform complicated humming patterns, the Draeger device uses a patented blow pattern making the device extremely easy to use. It helps insure that the air channel is clear of any interference while also ensuring that a real human — rather than something else — is actually taking the test. The user does not have to remember anything but how to breathe in and out when using the device.
  • Never Deactivate a Running Vehicle – A very important safety feature of the Draeger interlock device is that our devices will never deactivate your car or cause it to behave erratically should you either fail or fail to present a test after your vehicle is running. At no time will you have to stop your car in the middle of traffic to provide an additional sample to keep it running.
  • Stall Protection – As an additional safety feature, this interlock device affords a generous period of time between the engine being deactivated and the device resetting. This keeps the driver from having to present another sample of breath if his or her engine were to stall.
  • Replaceable Tubes – The breathing tubes in the interlock are replaceable, removable, and cleanable. This means that you can sanitize the surface that comes in contact with the user in the case of an illness or multiple users.
  • Fuel Cell Technology – This device employs an electrochemical fuel cell as the means of testing presented samples. This device insures that our interlock will only detect alcohol. Some devices actually detect cigarette smoke and other pollutants leading to false-positive readings. This will not be a worry with this device.
  • Advanced Data Logging – The data log in this device not only records violations, but also successful activations of the vehicle. Additionally, a great deal about each violation is recorded. This helps to ensure that there is a sufficient amount of information provided to see whether the driver simply used mouthwash, which would usually dissipate before the next test would be needed, simply changed his or her mind about starting the car, deactivated the vehicle before the retest time had lapsed, or many other situations. This added information greatly protects the driver from running into problems with violations at the DMV.

Can someone else drive your car if you have an interlock device?
  • Generally yes. As long as the person driving your car is fully licensed they are allowed to operate the vehicle. Because the ignition interlock device cannot determine who is trying to drive the car, anyone operating it will still have to take the initial test to start the car as well as any rolling retests that are required. It is crucial that anyone who will be driving your car (a spouse or teen for example) be fully trained on the use of the ignition interlock device. It is also important to remember that any failed tests will be logged no matter who is operating the vehicle.
