How Long Do I Need To Have An Ignition Interlock Device Installed for a First DUI Offense?

How long do I need the ignition interlock device?
How long do I need the ignition interlock device? The average length of time a driver will need to have an ignition interlock device is calculated by the number of DUI or DWI offenses on a record, and arrest-specific details about the charge. For a first DUI offense, a driver can expect to keep the ignition interlock device installed in any vehicle they drive for an average time of 6 months.

Ignition Interlock Device laws are strict for a first offense DUI. Driving under the influence of alcohol has serious consequences, beyond the worst case scenario of injuring or killing another person.

Intoxicated drivers who manage to avoid accidents are still easy targets for police officers to arrest, even in many cases with little evidence to prove DUI. After a first offense DUI conviction today, it is now now required to install an ignition interlock device (IID) in any vehicle driven by a DUI offender.

Will I have to get an Ignition Interlock Device installed for a first DUI, DWI offense? Under the new 2019 ignition interlock laws in every state, the DMV will require a person to install an ignition interlock device after a first DUI conviction for an average minimum length of 6 months time.

2 important facts every driver should know about the interlock device length of time and cost requirements today are:

  1. If a person were to get convicted of a second offense DUI within the next 10 years of the 1st offense, they will be required to have an interlock installed for 2 years.
  2. The overall average interlock device price of $1,800 covers a variety of things that includes the IID itself, a camera unit if required, mouthpieces, installation, removal, calibrations, reporting, device maintenance and other common interlock factors. The $1,800 price is the collective total average IID costs to expect after 6 months of use. A driver does not have to pay that entire cost upfront, but should be aware of what the total fees will add up to by the time the interlock device is removed after a first DUI offense.

An IID works like a breathalyzer device and is installed in the dashboard of a motor vehicle. The driver exhales into the IID before starting the car motor. If the measured blood-alcohol concentration (BAC) falls below the programmed BAC threshold, the motor will start. If measured BAC exceeds the preset BAC threshold, the IID prevents the engine from starting by interrupting the signal sent from the vehicle ignition to the starter.

How long a driver will have to install the Ignition Interlock device for a DUI, DWI charge can vary for each driver’s own arrest circumstances. When expert legal help is obtained early on after a DUI happens, there are legal defenses that work to implement ways how to get out of ignition interlock installation and avoid the cost of the IID requirement. However, when a driver misses their short window of time to fight and get around ignition interlock device installation, the average mandatory length of time the IID will be required is between 6 months up to one year upon a first offense drunk driving conviction.

Drivers who are able to provide valid breath samples below the BAC threshold are not out of the woods. The IID requires additional breath samples at random intervals while the engine is on. This prevents another individual from breathing into the device.

If a breath sample is not provided upon request or the sample exceeds the BAC threshold, the device emits a warning and alarm until the vehicle ignition is turned off or an acceptable breath sample is provided. Each missed or excessive BAC sample is logged by the IID for retrieval by law enforcement. Due to the complications and unintentional IID violations that can easily happen, every driver today should know what happens for your first DUI offense so the ignition interlock requirement can be avoided while there is still time to fight it.

Every state has some type of ignition interlock law today, with 29 states having mandatory IID provisions for DUI offenses. Though the National Highway Traffic Safety Administration recommends it for first offenders, some states do not require this car Breathalyzer installation for a first DUI or DWI offense conviction, but do give judges discretion to still impose this ignition interlock penalty. Several states impose stricter IID installation mandates for underage drinkers convicted of DUI.

Mothers Against Drunk Driving is one of several groups lobbying for mandatory Ignition Interlocks installation following an initial DUI conviction in any state. Some U.S. politicians support IIDs as standard features of motor vehicles. If they are successful, every car sold in the U.S. may someday have an IID installed in the dashboard.

DUI, DWI laws in the state in which the incident occurred determine whether IID installation is required for a first-time offender. Individuals charged with this offense should discuss their cases with DUI attorneys to find out if potential penalties include installation of IIDs. In most states under the new laws, the Ignition Interlock device installation is an alternative to first DUI license suspension length of time ranging on average of 6 months to 2 years.

If a person has been convicted of driving under the influence with a BAC over .08, or a breath test refusal offense, you will have to participate in the Interlock program, in order to get your driver’s license back. The IID program is designed as both a costly consequence and opportunity for an individual to get a license earlier by having this car Breathalyzer device wired into the ignition of any vehicle they will drive (including work or company cars).

An IID works much like a Breathalyzer test machine does. IID drivers are supposed to blow into the device before starting their vehicle, as well as submitting breath samples to the Interlock device while driving (every 15-30 mins) on average. A driver will be also required to have the device routinely maintained by a certified technician every 1 to 2 months.

Drivers facing their first DUI or DWI offense, who participate in the IID Program, will be expected to have to get the Interlock device installed in their vehicle for 1 year on average if convicted of the charge.

Besides the higher car insurance rates for 5 years after a guilty plea or conviction, first offense DUI drivers must also pay fines that start at $1,300 in most states. If a DUI, DWI case is still pending in court, many drivers may have defenses and alternate options to using the ignition interlock device than they are even aware of under new 2019 IID laws.

Drivers that need to install the Ignition Interlock device can expect to pay the following costs:

  • Average $160 installation fee
  • Monthly $30 administration fee
  • Daily monitoring charge approx. $3.50
  • $60 fee to remove the interlock at the end of the required installation time period
  • Additional fines will also apply if the device records any violations

  1. Thanks for answering my ignition interlock questions earlier, about how length of time you have to keep your ignition interlock device is directly correlated with the number of DUI convictions I received in court. The DMV said as first time DUI offender I will be required to keep the ignition interlock device installed in any vehicle I drive for a minimum of 6 months.

    I used to own a few houses and had a flawless record and accumulated a second offense DUI. Since then, I’ve been in a major rear end accident here and have a fully fused neck from this person who was texting and driving. I’m going to move and want to drive, but the DMV says only if I have an interlock device.

    I hope you can you help me as I don’t have a car now and have to take the bus to survive.

  2. Let’s say you had your 2nd DUI, you pledge guilty. The court sentenced you to pretrial detention, Scram device $400 a month, which has been seen to produce a lot of false positives, with lasts on average 4 mths. Court cost and fines 8k, DUI Schools $175, probation 1 yr. No license for 3 yrs.
    After all this you get your driver’s license back.
    Now the state law/court requires you to install the IID on your vehicles for one year at a cost of say 1k.
    Couldn’t you file that this maybe a direct violation of your 8th Amendment rights under the US CONSTITUTION,
    Excessive penalties and fines?
    IT seems that the DUI law carries more penalties/ fines than some felonies.
    Thank you for your time.

  3. Driving under the influence heavy fines and driver’s license revocation is bad enough already. I agree that every state has some type of ignition interlock laws now.
