Ignition Interlock Device

Ignition interlock devices, or IIDs, are electronic instruments that can detect the presence of alcohol for drunk drivers. They are a type of breathalyzer that detects blood alcohol content (BAC) levels. These car breathalyzers are usually installed as part of the standard DWI punishments in Houston, Texas.

They are hooked up to a car’s ignition system. In order to start the vehicle, the driver must blow into the IID for several seconds. If the driver’s breath has no presence of alcohol, the machine allows the ignition to complete and the car will start.

If alcohol is detected in the driver’s breath sample, the device will prevent the ignition from completing successfully and the car will be unable to start until an alcohol-free breath sample is supplied.

Texas IID Penalties

Submitting a breath sample containing alcohol into an IID will prevent a car from starting. The device will also record each time that a positive reading occurs. The driver’s probation officer will have access to the device’s records. Each time that the device is serviced, typically once a month, the information within the device’s computer is submitted to the driver’s probation officer.

Submitting a breath sample containing alcohol can result in:

Legal Defenses

Even though breathalyzers are widely used in Houston DWI cases, a great deal of evidence suggests that they are unreliable as blood alcohol content (BAC) calculators. This is especially true in the case of IIDs, or car breathalyzers.

Because these devices must be in a car at all times, they may be exposed to extreme hot and cold temperatures. They may be battered and damaged from falling to the floor of the vehicle. Any of these events can damage the sensitive instruments within the device, resulting in inaccurate readings.

Lawyers know about the faulty reputation of these devices and may be able to argue in court if a driver gets a false positive reading. This may result in penalties being suspended.

Hire an Ignition Interlock Device Attorney

Because IIDs are so inaccurate, there is a good chance you can get the charges dropped if you hire an experienced DWI attorney. When looking for an attorney to hire, it’s important that you consider his experience and practice area location. It’s best to choose a Houston attorney because he will understand how to courts operate in the area. See how Justin T. Surginer can help your case by calling 713-589-8855 today.
