FAQ’s about ignition interlock in Texas. Many times, similar questions are asked regarding ignition interlock devices or car breathalyzers. These include how much they cost, how they work, etc.

Here are some of the most frequently asked questions regarding these types of devices.

What Exactly is an Ignition Interlock?
This device analyzes your breath once it’s installed into our vehicle. This is done in order to prevent someone from starting the engine of their vehicle once they have finished drinking alcohol. If the device determines that your blood alcohol content is anywhere over the legal limit, the vehicle will fail to start and you will not be able to drive.

How Does This Device Work?
Before someone can drive a vehicle with this device installed, the driver must submit a breath sample by blowing into the device. If the end result is higher than the legal blood alcohol content, the vehicle will fail to start.

Why Would This Kind of Device Be Installed in My Vehicle?
If you ended up getting your driver’s license suspended due to either a DUI or DWI, the court may require this kind of device to be installed in your vehicle as a condition to have all of your driving privileges restored to you.

What Can Happen to an Offender if They Don’t Have This Kind of Device Installed?
The end result of something like this can include an additional suspension of all driving privileges.

How Reliable Are These Devices?
These devices are required to meet all standards imposed by the National Highway Traffic Safety Administration, which help to ensure that they are reliable. They are also tested by various independent laboratories.

Are They Effective?
The ignition interlock is considered to be perhaps the most effective tool to help fight against driving in which the driver of the vehicle is impaired, as the device prevents someone from driving while intoxicated due to not starting the vehicle if the driver provides a negative breath sample.

How Much Does This Device Cost?
Generally, the cost for this kind of device runs between $70 and $150 for installation, as well as $60 to $90 per month for both calibration and monitoring purposes.

Will There Be Damage to My Vehicle is a Device is Installed?
There will be no damage done to your vehicle since the device is connected to the wiring located under the dash and the hood. Both will be returned to their original condition once the device is no longer needed.

Can the Device Be Bypassed?
Yes, provided that the sober individual also rides in the vehicle with you since the device will randomly ask for running retests. However, if the test fails, the alarm horn will continue to honk until the vehicle is turned off. Additionally, assisting with circumventing this kind of device can result in fines and/or jail time.

Can Another Air Source Be Used to Imitate Human Breath?
No. These devices are equipped with temperature gauges and voice-tone monitoring, both of which can make the device abort any and all fake breath samples.

What Happens if a Breath Test Fails?
If this happens, a temporary lockout period will take place for the span of a few minutes for the first failed test. Additional failures will result in longer timeout periods.

Can Mouthwash or Medications Cause the Test to Fail?
Yes. Any product that contains alcohol will result in a failed breath test.

Can a Vehicle Be Left Running While the Driver is Inside a Building, Then Drive Away Afterward?
No. This is because random retests are often requested when the vehicle is running. If a sample is not provided when requested, the device will log a violation, which will cause the alarm horn to honk.

Can Providing a Random Retest Be Dangerous?
No. The driver will have a few minutes to perform the retest when asked, meaning they can find a place to pull over to perform it, which involves only breathing into the device.

How Often Should the Device Be Serviced?
Generally, every 30 to 60 days; however, if there are multiple violations, it could be serviced more frequently.

Can Other People Ride in a Vehicle with a Device Installed?
Yes. They must also use the device themselves and be responsible for any and all violations.

What if an Offender Has More Than One Vehicle?
Under the law, the offending driver is not permitted to drive any vehicle that does not contain one of these devices.

Is This Kind of Device Required in All States?
Not every state has imposed this type of law; however, judges are permitted to order that they be installed in vehicles.
