How Much Is an Ignition Interlock Device in Texas?

For those in Texas who have been convicted of a DWI, in some cases, they are placed into the ignition interlock program. If you are asking, "How much is an ignition interlock device?," its likely either you or a loved one has been ordered to install one of these devices.

The ignition interlock device cost depends on a number of factors, including the vendor, the length of the requirements, and any additional fees put in place by the court or state.

What Is an Ignition Interlock Device?

An ignition interlock device, also known as an IID, is a device installed into a vehicle's ignition system to test the driver's breath for alcohol. When the device is installed, the driver must offer a breath sample. If the device detects alcohol above the programmed limit, the vehicle will not start.

The person who has been placed into the program must cover all ignition interlock installation costs, as well as device costs, but they also must only get the device from a vendor who is regulated by the Texas Department of Public Safety, or DPS.

How Much Does an Ignition Interlock Device Cost?

There is not a statewide price for an ignition interlock device. Vendors may charge for installation and monitoring, and the prices for this often vary depending on the company and the circumstances.

For those who cannot afford the device, courts may offer options to get a more affordable ignition interlock device, or they might help with ignition interlock pricing by offering a payment schedule. In some cases, there is also a financial assistance program available.

What Other Ignition Interlock Costs Are Involved?

The IID itself is only part of the expenses associated with these programs. Depending on the situation, you may also have to pay an installation fee and you should also expect to pay maintenance costs. There might also be a lease fee or other costs associated with the vendor.

Again, Texas, and other states offer financial assistance, but even a low cost interlock device can be several hundreds of dollars.

Texas also has a $10 fee for an ignition interlock restricted driver license. DPS requires applicable reinstatement fees to be paid before an interlock license can be issued.

How Long Do You Have to Keep an Ignition Interlock?

The answer to how long you have to keep the IID really depends on a number of factors. Typically, it's based on why the device was ordered and the terms of the court order or license restriction.

For certain deferred adjudication cases involving DWI, Texas law requires an ignition interlock as a condition of community supervision unless the court determines that the requirement should be waived under the applicable law.

Texas law also addresses ignition interlock requirements connected with driver-license restrictions. The required period can vary based on the circumstances of the case.

Because the required period affects your total cost, it is important to find out exactly how long the court or DPS requires the device before choosing a vendor.

Does Every DWI Require an Ignition Interlock?

No. Whether an IID is required depends on the specific circumstances and the type of court or administrative restriction involved.

Some DWI cases involve an ignition interlock as a condition of bond, probation, deferred adjudication, or a restricted license. Other cases may have different requirements.

The rules can also differ based on the offense, prior convictions, license status, and court orders. You should not assume that another person’s IID requirement will be the same as yours.

Can You Drive Any Vehicle With an Ignition Interlock?

Generally, when you are subject to an ignition interlock restriction, you must follow the specific court and license requirements concerning which vehicles you may operate.

Texas DPS states that a restricted interlock license authorizes a person to operate a motor vehicle equipped with an ignition interlock device. Court-ordered installations must be completed by certified service centers.

If you drive a vehicle that does not meet the restriction, you could create additional legal problems. Ask your attorney or the appropriate court before driving a vehicle that is not equipped with the required device. For more information, this criminal lawyer in Fort Worth TX may be able to help.

What Happens If the Device Detects Alcohol?

An IID is designed to prevent a vehicle from starting when the breath sample indicates alcohol. Depending on the device and the circumstances, additional requirements or fees may apply.

Texas law specifically states that certain cost reductions for indigent defendants do not apply to fees that may be assessed if the device detects ethyl alcohol on the breath of the person attempting to operate the vehicle.

If you believe the device produced an inaccurate result, contact your attorney and follow the vendor’s procedures for documenting and addressing the issue. They can also share information on questions like what are dram shop laws?

Can You Afford an Ignition Interlock?

If you are concerned about the cost, do not simply ignore an IID requirement. Failing to comply with a court order or license restriction can create additional legal consequences.

Instead, ask whether you qualify for a payment arrangement or financial relief. Texas law allows courts to consider a defendant’s ability to pay certain costs associated with community supervision, including ignition interlock expenses.

A criminal defense attorney can help you understand which costs are required in your particular case and whether financial assistance may be available.
