DUI Ignition Interlock Requirements in Ohio

In addition to possible jail time and heavy fines, a conviction for operating a vehicle under the influence of alcohol (OVI/DUI) can result in a driver’s license suspension, having to use an ignition interlock device (IID) on your vehicle, and the collateral consequences that come with having a criminal record.

The installation of an ignition interlock device is only mandatory in certain OVI cases. If you have been arrested for drunk driving, it is important that you understand the DUI ignition interlock requirements and how a qualified Cincinnati DUI lawyer can help you avoid an OVI conviction.

What Is an Ignition Interlock Device?

An ignition interlock device is a breathalyzer connected to a vehicle’s ignition system. The driver must blow into the device and provide a breath sample with a blood alcohol concentration (BAC) below a preset threshold to start the vehicle. These devices are designed to prevent impaired driving and record test results for court or probation review.

Under Ohio Admin. Code 4501-45, IIDs must be state-certified and include features such as rolling retests and tamper alerts.

When Are Ignition Interlock Devices Required in Ohio?

While IIDs are not automatically required for every OVI offense, there are specific circumstances where they are mandatory or strongly encouraged by the court.

• First-time offense (BAC ≥ 0.17%): May be required for one year.
• Second OVI within 10 years: Mandatory installation of an IID.
• Third or subsequent offenses: IID is required, and penalties are more severe.
• Test refusal (Implied Consent violation): Can trigger IID requirement to regain driving privileges.
• Underage DUI (OVUAC): May result in an IID order at the judge’s discretion.

Annie’s Law & Ohio’s IID Incentives

House Bill 388, or Annie’s Law, went into effect in 2017 and expanded the use of ignition interlock devices in Ohio. One of the law’s key provisions is that first-time OVI offenders can request driving privileges if they agree to install an IID for the duration of their suspension.

Additionally, the court may reduce a license suspension by up to 50% if an IID is installed. Annie’s Law also increased the OVI “look-back” period from 6 to 10 years, making more individuals subject to repeat-offender penalties.

IID Violations & Penalties

Violating IID requirements can result in severe consequences, including longer suspension periods, jail time, and the loss of limited driving privileges. Violations may include:

• Failing a breath test with alcohol detected (often set at 0.02% BAC or higher)
• Refusing a retest while driving
• Tampering with, bypassing, or removing the device
• Driving a vehicle not equipped with an IID

If a violation occurs within 60 days of a suspension ending, the court may automatically extend the suspension by an additional 60 days. Repeat violations can also lead to remote alcohol monitoring or reinstated jail time.

Costs of an Ignition Interlock Device in Ohio

Ohio law requires the offender to cover all IID-related expenses. On average, this includes:

• Installation: $75–$150 (one-time)
• Monthly maintenance: $70–$100
• Removal fee: ~$50

All devices must be installed by state-approved providers and often include a camera to verify the identity of the person blowing into the device.

Can You Regain Driving Privileges With an IID?

Yes. If your license was suspended due to an OVI, you may be eligible to petition for limited or unlimited driving privileges by agreeing to install an ignition interlock device. This may allow you to drive to work, school, medical appointments, or court-mandated programs—even during the suspension period.

Under Ohio Revised Code 4510.022, judges have discretion to approve these privileges and impose additional conditions.

Frequently Asked Questions About Ignition Interlock Devices in Ohio

Is an ignition interlock device mandatory for a first-time OVI in Ohio?

Not always. For most first-time OVI offenses, a judge has discretion to order an IID. However, if your BAC is 0.17% or higher, or if you refused a chemical test, an IID may be required to reinstate your driving privileges.

How long do I have to use an ignition interlock device in Ohio?

The duration depends on your offense level. First-time offenders may need an IID for six months to one year. The requirement can range from two to five years for second or third offenses. Violations can extend the IID period.

Can I drive any car with an IID restriction?

No. If a court orders an ignition interlock, you can only drive vehicles equipped with the device. Driving a vehicle without an IID under court order is a violation and may result in additional penalties or jail time.

What happens if I fail the breath test on my IID?

If your breath alcohol content is over the device’s limit (typically 0.02% BAC), your vehicle will not start. Multiple failed attempts may be reported to your probation officer or the court and can result in a violation of your sentencing terms.

What qualifies as an IID violation in Ohio?

Violations include tampering with the device, failing to provide a breath sample, having a BAC above the threshold, or driving a non-equipped vehicle. Courts may respond by extending your suspension or reinstating jail time.
