LifeSafer® L250

An Ignition Interlock Device (IID) is an in-vehicle breathalyzer device that is connected to the ignition system of a car, truck or motorcycle. You will be required to blow in the device prior to starting your car. If the breath sample contains alcohol, the IID prevents the vehicle from starting. 

Lifesafer IID is known for being one of the smallest on the market, making it discreet and easy to use.

The device works by measuring the breath alcohol concentration (BAC) of the driver. If the BAC is above the pre-set level, the device will prevent the vehicle from starting. After having a failed breath test, the driver must wait a pre-determined amount of time, usually 15 minutes, before attempting to start the vehicle again.

You will need to blow into the device’s mouthpiece as instructed by the device’s manual or your service provider. Be sure to blow firmly and steadily into the mouthpiece for at least 5 seconds to ensure an accurate reading.

If you fail a breath test, the interlock will enter a temporary lockout period for the first failed BAC test. This lockout time is set by state regulation. If you fail the re-tests, your car may lock out for a longer period or need a reset and tow, depending on state law. The retest feature gives a chance for the alcohol to dissipate from the mouth if you accidentally ingested something that trigged a BAC. It’s a good idea to rinse your mouth out with water prior to taking the test and avoid any products that may contain alcohol. These can result in a positive alcohol reading, which is very frustrating. Depending on your state’s laws and your service provider’s policies, multiple failed breath tests may result in your service provider being notified and additional penalties, such as fines or additional restrictions on your driving privileges.

Some changes to your routine may be required — for example, toothpaste, mouthwash, and hand sanitizer all contain trace amounts of alcohol that can trigger an alcohol reading. So can some medications and foods. Environmental substances such as windshield washer fluid and gasoline fumes also contain alcohol and can inadvertently trigger the device. If you receive a fail and haven’t been drinking, take a moment to rinse your mouth, check the surroundings and make sure the air inside your vehicle is circulating, then try again when prompted by the device. Note that if you have consumed alcohol, even if it was the prior evening and you are trying a morning start, your BAC may be high enough that you fail the test. Best practice is to not drink any alcoholic beverages while you are on your program.

If you do not allow sufficient time for the alcohol to dissipate from your mouth, FAIL will be registered in the memory. You will have the opportunity to re-test, and rinsing your mouth with water can help. It can be hard to change routines to accommodate an interlock, but it will get easier over time. Other common products that contain alcohol include hand sanitizer, air freshener, windshield wiper fluid, cleaning products, and wipes. Many foods contain trace amounts of alcohol as well — vanilla extract is an example you may not have considered. It’s also a good idea to avoid tobacco, coffee and vaping when you use an interlock.

You should take any and all precautions as recommended by the CDC and WHO regarding hand hygiene and the use of alcohol-based hand sanitizer. If alcohol-based hand sanitizer is used, you should take the following steps when taking an interlock test to help avoid registering an alcohol reading.

– Apply the sanitizer outside of the car.

– Allow the sanitizer to air dry completely before you enter the car to take a test.

– As an added precaution, you should roll down a window to encourage outside air circulation.

– As always, we recommend that prior to taking a test, you rinse your mouth with water to remove contaminants.

Yes, in some states. In fact, we are the only interlock provider who can install on a motorcycle.

No, the interlock will never turn off a running vehicle. If a retest is missed or failed the horn will sound, a violation will be recorded and the device will require early service.

Our devices are equipped with stall protection. The interlock will allow a restart without a test for two minutes. 

NOTE: If you have a vehicle that includes an economy feature that shuts off the engine while you are at a red light, in traffic, etc it will need to be disabled so that you do not have to constantly re-test.

In most states, 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. Check with us to see if other drivers are allowed to use the interlock.

No. Having anyone else take the test and then have you start driving is considered circumventing the device. 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.

It is VERY important that you call us before any work is completed on your vehicle. States require detailed information about the shop doing the work. This documentation assures the unit will not record a tampering event if the power to the vehicle is interrupted as the unit will record the power disconnect and the reconnect. We can also provide your service provider with an override code so that they can test drive the car and turn it on and off during the repair process without having to use the interlock.

It is best to not drink at all if you are participating in an ignition interlock program.  Even drinking the night before you try to start your car may result in a BrAC that causes a violation.   The tolerance for an ignition interlock (IID) to produce a violation varies by state, but is very minimal and most people who need an interlock installed also agree with the court to abstain from alcohol.   We strongly advise not consuming any alcoholic beverages, checking your personal care products (such as mouthwash and toothpaste) to make sure they don’t contain ethanol or other chemical variants of alcohol.   Your success is important to us, and remaining alcohol free is a very important part of that.

The length of time a customer will have to have an IID (ignition interlock device) in their vehicle depends on the specific laws and regulations of their state or jurisdiction, as well as the court or agency that ordered the IID to be installed. In general, the length of time can vary from a few months to several years. It is best to consult with the court or agency that ordered the installation of the IID to determine the specific length of time required.

The restriction time generally begins once the IID is installed in the vehicle, but it’s important to check with the court or agency that ordered the installation of the IID to confirm the specific start date. Some jurisdictions may have specific requirements that must be met before the restriction period begins, such as completing a certain number of hours of alcohol education or treatment.

If a customer receives an ignition interlock device (IID) violation letter, they should take the following steps:

Review the letter carefully to understand the specific violation that occurred, such as a failed breath test or missed service appointment.

Contact the IID provider to discuss the violation and any possible issues with the device.

Follow any instructions provided in the violation letter, such as scheduling a service appointment or providing additional documentation.

Comply with any penalties or additional requirements imposed by the state, such as additional IID use period or fines.

Consider seeking legal advice if the customer feels that the violation is unjustified or that their rights were violated.

It’s important to address the violation promptly to avoid any additional penalties or suspension of driving privileges.

Lifesafer takes the accuracy of their ignition interlock device (IID) seriously. One way the company ensures the accuracy of its device is through a process called calibration. During calibration, the device is checked to ensure that it is providing accurate blood alcohol concentration (BAC) readings. This can be done by using a known alcohol solution or by having a person blow into the device with a known BAC. The device’s readings are then compared to the known BAC to determine the accuracy of the device. Additionally, Lifesafer conducts regular laboratory testing to ensure its devices meet the required standards and specifications set by the National Highway Traffic Safety Administration (NHTSA) and other regulatory bodies. The devices are also subject to regular inspections and maintenance to ensure they are working properly. It’s also important to note that the accuracy of the IID also depends on proper usage and maintenance of the device by the customer, such as regular calibration checks and following the instructions provided by the manufacturer.

Your device will have a series of self-diagnostic tests that can be performed to ensure it is functioning correctly. If you suspect your device is not working properly, contact your service provider for assistance.

The Lifesafer IID device will record your test results and other data, and this information may be shared with the court or other authorities as required by law. 

Our devices can accommodate customers with hearing impairment by installing a warning light to alert customers when the device is prompting for a test.
