What Is an Ignition Interlock Device?
An ignition interlock device is a breath-testing device installed in a vehicle. Before starting the car, the driver must blow into the device. If alcohol is detected above a preset limit, the vehicle may not start.
In addition to the initial test, many devices require periodic retesting while driving to ensure continued compliance. These devices are designed to promote safe driving and may be required by courts or administrative agencies in Texas.
When Are Ignition Interlock Devices Required in Texas?
The requirement for an ignition interlock device in Austin and Travis County depends on several factors. While not every DWI case involves an IID, courts may order one under certain circumstances.
As a Condition of Bond
After a DWI arrest, a judge may set bond conditions that include installation of an ignition interlock device. This is more likely if:
- The alleged blood alcohol concentration (BAC) was 0.15% or higher
- There is a prior DWI conviction
- The case involves an accident or other aggravating factors
In these situations, the IID may be required while the case is pending.
As a Condition of Probation
If a person is convicted of DWI and placed on community supervision (probation), the court may require an ignition interlock device as a condition of that supervision.
The length of time the IID is required may vary depending on:
- Whether it is a first or subsequent offense
- The specific terms set by the judge
- Compliance with probation conditions
For Occupational Driver’s Licenses
If your license has been suspended and you apply for an occupational driver’s license, the court may require an ignition interlock device as part of the approval.
This is common in cases involving alcohol-related offenses, particularly when public safety concerns are present.
Repeat Offenses and High BAC Cases
Texas law may require ignition interlock devices in certain repeat offense situations or when the BAC exceeds a specific threshold. For example:
- Second or subsequent DWI offenses may carry mandatory IID requirements
- High BAC cases (0.15% or higher) may increase the likelihood of an IID order
A criminal defense lawyer in Austin may help you understand how these rules apply to your case.
How Long Is an Ignition Interlock Device Required?
The duration of an ignition interlock requirement can vary widely depending on the circumstances. It may last:
- Several months during a pending case
- The full term of probation
- A court-determined period after license reinstatement
In some cases, early removal may be possible if all conditions are met, but this depends on court approval.
Costs Associated with Ignition Interlock Devices
Installing and maintaining an ignition interlock device involves several costs that individuals should be prepared for.
Typical expenses may include:
- Installation fees (often ranging from $70 to $150)
- Monthly monitoring fees (approximately $60 to $100)
- Maintenance and calibration costs
These expenses are usually the responsibility of the driver and can add up over time.

What Happens If You Violate IID Requirements?
Failing to comply with ignition interlock requirements can lead to serious consequences. Violations may include:
- Attempting to start the vehicle with alcohol in your system
- Missing required maintenance or calibration appointments
- Tampering with or removing the device
Depending on the situation, consequences may include:
- Extension of IID requirements
- Revocation of bond or probation
- Additional legal penalties
A criminal defense lawyer may help address alleged violations and explain your options.
Can You Drive Any Vehicle with an IID Requirement?
In most cases, if a court orders an ignition interlock device, it must be installed on any vehicle you operate. This can create challenges if you:
- Share a vehicle with family members
- Drive a company vehicle
- Need to operate multiple vehicles
Some courts may allow exceptions, but these are typically limited and require approval. It is important to follow all court orders carefully to avoid additional penalties.
