Ignition Interlock Device

A drunk driving defense lawyer in Texas can fight for you

An ignition interlock device (IID) is one of the newer penalties used in Texas against individuals convicted of DWI. The IID is a breath test device, also known as a deep lung air device and about the size of a cell phone. It is installed into every vehicle that someone convicted of DWI owns or leases. If you are ordered to use an IID, you will need to give a breath sample to start the car. The car will only start if your blood alcohol concentration is less than a certain level. If you don't give a sample, or the machine detects that your BAC exceeds the threshold, the car will not start.

IID laws vary from state to state. An ignition interlock device may seem like a good idea on the surface. For someone who is convicted of drunk driving, the device can be proof that the individual is staying sober and driving responsibly.

However, potential problems with the ignition interlock device have surfaced since the IIDs have been used. The devices may detect alcohol on a driver who recently used mouthwash or who ate baked goods that contain yeast and sugar, which may cause low alcohol levels. The IID also may malfunction, leading to false positives or incorrect readings. And some people need to share their vehicle, which means the other driver will have to use the IID.

The IIDs also include an installation fee and monthly rental fee, which can create a financial hardship.
