- Once your IID is installed, your IID vendor will submit proof of installation to us
Get an IID installed out of state
If you need to meet the requirements for IID in Washington but either no longer reside here, or need to have an IID installed outside of Washington, you must submit an out-of-state ignition interlock status verification form. Please fill out this form and either print on white paper and fax to 360-570-4961, or scan and email to interlock@dol.wa.gov.
This form allows an ignition interlock company representative to report that:
- A Washington State Patrol-certified ignition interlock device has been installed.
- An ignition interlock device has been removed or is no longer functioning.
- The driver hasn't had any incidents in the previous 4 months which would prevent removal of the interlock restriction.
Vehicles that require an IID
You'll need to have an IID installed in any vehicle you drive.
Employer vehicles
If you operate an employer-owned vehicle during work hours, you may submit an Employer Declaration for Ignition Interlock Exemption to us so they don't have to install IIDs on their vehicles.
- You can't submit this form if the employers vehicle is assigned exclusively to you for commuting to and from work. It would need to have an IID installed before you drive it.
- Submit the form to us before you drive any employer's vehicles.
- Carry a copy with you whenever you drive an employer vehicle.
IID requirement period
The IID requirement period is how long you'll be required to have an IID. To find out how long, see Learn how to reinstate my license.
- 1st offense: At least 1 year.
- 2nd offense: At least 5 years.
- 3rd or subsequent offenses: At least 10 years.
Tolling requirements
These requirements are for violations and deferred prosecution findings as of June 9, 2016. This means that you must have the IID installed for your entire requirement period. You'll receive day for day credit towards your requirement period for each day the device is installed in a vehicle. If a device is removed, tolling stops and won't begin again until you have the IID reinstalled.
For example:
You're convicted of a violation that occurred September 1, 2016, you're required to have a device for 365 days:
- December 27, 2016 – device is installed
- April 6, 2017 – device is removed, this equals 100 days that have been fulfilled
- May 31, 2017 – device is reinstalled
- February 24, 2018 – Date you may request your certificate of compliance if there are no more removals or failed attempts.
If you have your IID removed before fulfilling your IID requirement period, your license will be suspended.
Certificate of compliance
The certificate of compliance is the document submitted by your IID vendor to us at the end of your IID requirement period. When you're finished with your requirement period contact your IID vendor to request the certificate of compliance. They'll submit the certificate if you have not done any of the following in the last 4 months or the last 180 days:
- Attempting to start the vehicle with a breath alcohol content of .04 or more
- Failed to take or pass any required retest
- Failed to schedule maintenance for your IID such as repairs, calibration, monitoring, inspection, or replacing the device
If you violate any of the above, you'll need to re-start your certificate of compliance time period.
Your certificate of compliance requirement is based on your violation date:
- Before July 23, 2017, your compliance period will be the last 4 consecutive months of your IID requirement period.
- On or after July 23, 2017, your compliance period will be the last 180 consecutive days of your IID requirement period.
- As of September 1, 2018 any convictions received with a conviction date after July 23, 2017 will require a 180 day certificate of compliance.
Medical tolling exemptions
You may be eligible for an IID medical exemption if:
- You had an alcohol/drug violation.
- You're not physically able to operate an IID.
You won't be able to drive but the exemption allows you to earn day for day credit towards your IID requirement period as though a device was installed.
To apply for a medical exemption:
- Complete the Driver/Patient information section of the Ignition Interlock Device Tolling Medical Exemption form.
- Take the form to your doctor for an exam and have them complete the Medical provider section. The exam must have been done in the last 30 days.
- Your doctor may indicate a temporary condition that says you're not able to meet the minimum breath requirements. If this is the case, the exemption is only good to the date that's decided by the doctor.
- Your exemption could be good up to 1 year, if you have a permanent or progressive condition that could last longer than a year. You will need to submit a new exemption form each year before the current exemption expires.
After we receive your form, we'll review it to determine:
- If the form is signed by a licensed medical provider (MD, DO, RN, ARNP or PA).
- If the doctor indicated that you can't meet the minimum breath sample requirements.
- If the exam was completed in the last 30 days.
- If you currently have an IID installed on file.
After we review your form, we'll send a letter letting you know if you've been accepted or denied.
- If you're accepted, you'll get day for day credit towards your IID tolling requirement. Your credit won't start until we have processed and approved your application.
- If you're denied, you can submit a new form.
