What should you expect at an ignition interlock service appointment?

So you have been sentenced to an Ignition Interlock Device, installed on your car, and have started to meet the requirements of your restricted driver’s license. Then someone will ask you about the upcoming service appointments that you will need to return to the location every month or so for the duration of your interlock program. And at your first service appointment – what will happen then? No one seems to know.

One thing I have noticed is that most people have an extreme amount of confusion before the first interlock service appointment. Most people’s fears are typically worse than reality. This article will serve as a guide to all the people who are nervous for their interlock service appointment.

It’s less dramatic than you’re probably imagining

At the service appointments for your interlock device, the appointments are typically routine in nature and can last anywhere from 30 to 45 minutes. The technician downloading the information from your interlock and then reviewing that information to check for any unusual activity. The technician also will perform any required maintenance, as needed to keep the interlock working properly. This could include re-calibrating the sensor.

When the technician does perform a service appointment for you the technician will download the data log from your interlock device. The data log contains a detailed record of every single breath test that was taken by you for the interlock device as well as the results for each of the individual breath tests. The interlock device also keeps a record for every start attempt for your vehicle as well as the end of the interlock monitoring period for your vehicle. All of the information in your interlock device’s data log is uploaded to a monitoring authority (i.e. court, DMV, state program administrator, etc.) upon completion of the service appointment. In most interlock monitoring programs the program administrator can view results from the interlock device in real time online. Since the interlock device reports all information to the program administrator automatically and the interlock device reports all information to the program administrator without discrimination there is no favoritism with the interlock device as to which information will be reported and which information will not be reported by the interlock device. The interlock device reports information to the program administrator much like a video camera would record events and then have the recorded events played back to another person.

What the technician is actually doing under the hood

The interlock can be pre-set to calibrate after a predetermined amount of time. This is in order to keep the sensor at the optimal level and to take in to account any external factors that may affect readings. For example a guitar can go out of tune after a while, not because the guitar was of poor quality, but because the wood of the guitar has shifted and the strings have settled. The humidity can also affect the guitar going out of tune, but this can be adjusted for. Similarly the interlock’s sensor can go out of tune over time, and this is corrected by the calibrating of the interlock.

Beyond calibration, here’s what a typical appointment covers:

• Download the device’s stored data log and transmit it to the monitoring authority
• Calibrate the breath sensor to ensure readings stay within the required accuracy range
• Visually inspect the device for any signs of tampering or physical damage
• Check the camera (if your device has one) to confirm it’s functioning correctly
• Update device firmware if a software patch is available

Some interlock systems can also be monitored via GPS tracking. Problems can occur if the individual is normally driving within a particular geographic area but then goes on a long road trip.

Appointments – when and how long

Another item to be aware of is that if you fail to have a service appointment scheduled or show up late for an appointment, your interlock device will lock you out of your vehicle until service is completed. The time frame for scheduled service is listed on your paperwork however if you have lost your paperwork you can call your service provider to confirm your scheduled service appointment. ignition interlock Charlottesville VA provides service for interlock devices in the central Virginia area and can answer any questions you have regarding scheduled service for your interlock device.

There are many organizations that have offices in central Virginia, and many of these organizations can assist the interlock service user who resides in this part of the state. Examples of programs administered by organizations that have offices in central Virginia that can assist the interlock service user who resides in this part of the state, would include monitoring for blow tests that are below permitted levels and scheduling of required service appointments for devices installed in vehicles of drivers required to be monitored as part of a penalized driver program. Resources related to programs that are administered by organizations that have offices in central Virginia which can assist the interlock service user who resides in this part of the state are included below.

Flag List

While many flags recorded by an ignition interlock device are in violation of a persons driving privileges there are also many flags recorded that are not in violation of a persons driving privileges. When a person finds out that their device recorded a number of flags they are often concerned. However, it is best for the person to first find out what each flag could mean before panicking.

Logged event	What it indicates	Does it automatically cause a violation?
Failed startup test (BAC above limit)	Alcohol detected at or above the device threshold	Usually yes, reported to monitoring authority
Missed rolling retest	Vehicle was running but no retest was completed in time	Often flagged, may or may not be a formal violation
Power disconnect	Battery was disconnected or lost power	Flagged, reviewed for context
Failed rolling retest	Alcohol detected during a mid-drive retest	Typically yes
Circumvention attempt detected	Tampering or bypass behavior suspected	Serious flag, almost always reported

Another important point to consider is that monitoring authorities are required to review all information in its proper context. A single incident of a power disconnect for example (i.e. the car’s battery died while parked in a grocery store parking lot) will be viewed very differently from a string of repeated power disconnects. If you have been flagged for a reason and are concerned about the status of your record, you should speak with an attorney.

Understanding how modern monitoring systems and connected technologies work can make technical processes feel far less intimidating, and Tech Coore publishes easy-to-follow articles that help readers stay informed about today’s digital world. 

What to bring to your service appointment for your ignition interlock device.

1. Your program paperwork or confirmation number from your last appointment
2. A valid ID
3. Your vehicle, with enough fuel to idle comfortably during the inspection
4. Any documentation your monitoring authority specifically requested

Plan to arrive at the service center about 15 minutes prior to your scheduled appointment time. The service center will have many appointments scheduled for the same time. In addition to wanting to be on time for your appointment, you do not want to have to worry about dealing with the service center’s staff about being late for your appointment and incurring a penalty. Also, remember that the only thing that you will have to do at the service center is to test your interlock and the service center’s technician will perform all of the other steps in the process of servicing your interlock. All you have to do is to arrive at the service center, sign-in, and wait for the service center’s technician to perform a test or two with your interlock. This is one of the easiest part of the interlock program.

More About The Interlock Service Appointments

The hardest part of the interlock program is daily testing – blowing before each drive, the retests while driving, and those dreaded morning tests. The interlock service appointments are simply where all of the data from your interlock has been recorded and someone checks over the interlock and its’ sensors to ensure proper operation.

I know that everyone fears their first appointment, but I can tell you that after the first appointment, the next appointment is nothing. Not so great going in, but so fine coming out.
