An ignition interlock is a device that measures the alcohol in your breath and allows you to start your vehicle if it is below the set point. The device also requires periodic retests while the vehicle is running. The interlock records a number of items including test results, engine starts and vehicle run times. Any violations, for example failed tests or missed retests, are recorded by the device.
Most alcohol impaired driving offenders choose to drive illegally with a suspended or revoked license. An Interlock Program provides a control mechanism to prevent them from driving intoxicated.
The goals of an interlock program are as follows:
Yes, the National Highway Traffic Safety Administration has established standards for all ignition interlock devices. Independent laboratories test the devices to ensure they meet NHTSA’s strict requirements.
Yes. The interlock is usually serviced every 60 days, more frequently if there are any violations. If the device is not serviced as scheduled it will go into lockout and the vehicle will not start. During service appointments, your LifeSafer service provider downloads recorded information from the device. The logged information is then supplied to the authorities for review
Several days prior to a service appointment, the service light on the unit starts flashing as a reminder of an upcoming appointment. Also, for several days following the scheduled date the service light will remain steady and a tone will sound as an overdue indication. If you fail to return to the service center within this time frame the interlock device will enter a permanent lockout condition to prevent further operation of the vehicle. Then, the vehicle would have to be towed to the service center or the center personnel would have to perform remote service.
The interlock will enter a temporary lockout period of a few minutes for the first failed BAC test, and a longer lockout for any subsequent failed BAC test. This permits an opportunity for the alcohol to dissipate from the mouth and for you to consider the reason for the failed BAC test.
If you do not allow sufficient time for the alcohol to dissipate from your mouth, FAIL will be registered in the memory. During the training session a caution is emphasized to all participants about the use of mouthwash or other common substances that contain alcohol.
Yes, however the unit will detect that the vehicle has been started without a valid breath test and require a breath sample. If a passing breath test is not given the alarm horn will start honking and a START Violation will be logged into the memory and the interlock will activate early service recall.
No, the interlock will never turn off a running vehicle. If a retest is missed, the horn will sound, a violation will be recorded and the device will require early service.
The interlock will allow a restart without a test for two minutes.
No, the unit has no means of interrupting operation of the vehicle once it is started.
Yes. LifeSafer service providers will train other users of the vehicle at no additional charge. However, please note that anyone driving the vehicle will need to use the interlock and you will be responsible for any violations.
No, most states have laws that include fines and jail for individuals assisting in the circumvention of an interlock. Additionally, interlocks randomly ask for additional tests while the engine is running. If the retest is not taken or failed, the unit will log a Retest Violation and the alarm horn will honk until the vehicle is turned off. Many states use camera interlocks that take a picture during each test as a measure against this type of circumvention.
No. when the interlock device signals for a running retest, you have a few minutes to provide the sample or to pull over to the side of the road in a safe area to provide the breath sample. There are no buttons to push; you must only breathe into the unit to complete a breath sample.
You need to contact the service center prior to having service conducted on your vehicle in the event that the repair shop has questions about the interlock. Documentation must be provided if the power to the vehicle is interrupted as the unit will record the power disconnect and the reconnect.
No. The unit has a back up lithium battery to protect the data log in memory.
No. Proprietary software and a special interface connection is needed to communicate with the device.
No. LifeSafer service providers are experienced in vehicle wiring. They will professionally install the system and when the device is removed the vehicle wiring will be securely restored.
Most states currently have interlock programs in which service centers can assist you. You will need to contact your primary service center to be routed to the closest center for assistance.
The unit can self diagnose problems and you will be able to confirm if the unit is having problems by the condition of the service light. Remote service is available for such emergencies.
No, currently available devices have anti-circumvention techniques, such as voice-tone monitoring, which cause the interlock to abort artificial breath samples.
No, the unit will randomly ask for breath tests while the vehicle is running, if a sample is not given when requested, the device logs a Retest Violation and the alarm horn starts to honk until the vehicle is shut off.
¡Si! Service, training, materials, and technical support are offered in both English and Spanish.
Driving under suspension without a required interlock is illegal. Not installing an ignition interlock that has been mandated by a court or DMC can carry serious consequences, including substantial fines, jail time, and possible felony charges. Your insurance will also go up.

If the LOCKOUT light is displayed, your vehicle will temporarily not operate because of too many fails or aborts. This temporary lockout will last for 2-5 minutes. When the message is cleared from your device you will be able to retest.
If both the SERVICE and LOCKOUT lights are glowing, but NOT flashing, your vehicle will not operate and your device and vehicle are in permanent lockout. You are not able to test during a permanent lockout. You should call your service provider to make arrangements for your device to be reset.
If you are past due for your scheduled program monitoring, or if you are in early recall, both the LOCKOUT and SERVICE lights will flash. The number of times the lights flash together in sequence equals the number of remaining days before the device goes into a permanent lockout. You should call your service provider immediately to schedule an appointment for service and monitoring.
The WAIT light may stay on for an extended period of time during cold weather. The unit will remain on WAIT until it has warmed up to operate properly. Ask the technician at your next service appointment about setting a warm-up time on your device to help reduce your ‘WAIT’ time.
If the POWER light keeps flashing this indicates that your vehicle’s battery is weak or its voltage is low.
The ABORT light appears if an improper breath test was given. The device did not receive either the correct amount of air pressure and/or the hum tone that was needed. This is NOT a fail. Continue to test as normal.

Using a LifeSafer ignition interlock is easy — more than 750,000 people have done it — but there are a few things you need to know. At your installation one of our experienced technicians will take you through the steps so that you can operate the device without a hitch. Here is what you need to do in order to start your vehicle with a LifeSafer ignition interlock:
When you enter your vehicle, turn the key to the “on” position (do not start the car).
When the device is ready, you will have one minute to blow into the device, or it will be necessary to start the test again.
Relax and blow steadily into the device while humming a tone for 5 to 7 seconds (during installation you will have a chance to practice so that you know how best to do it). The device will emit a tone, indicating that you are doing the test correctly. Continue blowing until the tone stops. A green light “Pass” will flash and another tone will sound, indicating that you are done.
When the green “Run” light flashes, you can start your vehicle and drive. The device will stop flashing and display a solid green light while you are driving.
