At LifeSafer, we understand that dealing with legal issues can be overwhelming. Our goal is to make the process as easy and stress-free as possible. If you are required to install an ignition interlock device, you probably have a lot of questions. Here are some frequently asked questions and answers to help you better understand what an IID is, how it works and locations near you in Texas. 

What is an ignition interlock device?

An ignition interlock device, also known as an IID, is a small in car breathalyzer. The driver has to provide a breath sample before the car starts. If the device detects alcohol, the engine will not start. An ignition interlock device is often required as a condition of probation for DWI offenders.

How does an ignition interlock device work?

To start your vehicle with an IID installed, you must first blow into the device. The device will then analyze your breath sample to determine your blood alcohol concentration (BAC). If your BAC is below the predetermined limit, the engine will start. If your BAC is above the limit, the engine will not start. Additionally, the device will require random breath tests while you are driving to ensure that you remain sober.

So what is the Legal alcohol limit in Texas?

The legal alcohol limit for regular drivers is 0.08%, while for those who possess a commercial driver’s license, the limit is 0.04%. This applies to both personal and work vehicles. If your blood alcohol level is found to be 0.15% or higher, you may be convicted of a Class A misdemeanor. If the level falls between 0.08% and 0.15%, the offense is usually considered a Class B misdemeanor.

How much does an ignition interlock device cost in Texas?

The cost of an ignition interlock device varies depending on the provider and the state you live in. In Texas, the average cost of an IID installation is $70-$150, and the monthly service fee ranges from $60-$100. You may also be required to pay additional fees for maintenance and calibration of the device. LifeSafer is transparent about cost and has several options for payment.

Is it necessary to have an ignition interlock device installed?

If you have been convicted of a DWI offense, it is likely that you will be required to have an IID installed as a condition of probation. Additionally, if you are caught driving without an IID when one is required, you may face additional legal consequences. It is important to comply with all court-ordered requirements to avoid further legal issues.

Can I drive any vehicle with an ignition interlock device installed?

If you are required to have an ignition interlock device installed, you will only be permitted to drive vehicles that have an IID installed. It is illegal to drive a vehicle without an IID when one is required.

How long do I have to use an ignition interlock device in Texas?

The length of time that you will be required to have an ignition interlock device installed varies depending on the state you live in and the circumstances of your offense. In Texas, the minimum requirement for first-time offenders is six months, and the maximum requirement is two years.

Can someone else blow into the ignition interlock device for me?

No. It is illegal to have someone else blow into the ignition interlock device for you. The device is designed to detect when someone other than the driver is attempting to provide a breath sample.

What happens if I fail a breath test while using an ignition interlock device?

If you fail a breath test,  the device will record the failed test and prevent the car from starting. Depending on the circumstances of the failure, you may be required to take additional tests or face legal consequences.
