Washington DOL won't approve your restricted license until you show proof of IID installation — but most installers won't schedule you without a valid license number. Here's how to break the circular dependency.
Why Washington's IID-First Requirement Creates a Scheduling Trap
Washington DOL requires proof of ignition interlock device installation before approving your restricted license application. You submit the DS-9 application, the Occupational License Statement, employer verification, and proof of SR-22 filing — but without an IID installation certificate from a state-approved vendor, DOL returns your paperwork unprocessed.
Most IID vendors (Smart Start, Intoxalock, LifeSafer, Guardian Interlock) require a valid Washington driver license number to schedule installation. Their intake forms check license status in real time. If your full license is suspended and you don't yet have a restricted license number, the online scheduler rejects the booking or flags it for manual review.
You need IID proof to get the restricted license. You need the restricted license number to book IID installation. DOL's own DS-9 instructions don't explain how to sequence this correctly, and most DUI attorneys submit the restricted license application before arranging IID — assuming the client can book installation after approval — which adds 10-15 days to an already tight timeline.
The Procedural Workaround Most Vendors Won't Advertise
Call the IID vendor directly and request a pre-license installation appointment. Smart Start, Intoxalock, and LifeSafer all offer this — it's not advertised on their websites, but their scheduler teams handle 20-30 of these calls per week in Washington. You'll need your full suspended license number, proof of SR-22 filing, and a copy of your DS-9 restricted license application showing DOL receipt.
The vendor schedules installation for 3-5 business days out. You attend the appointment, the device is installed, and the vendor emails the IID Installation Certificate to you and DOL within 24 hours. DOL's Impaired Driving Section cross-references the certificate against your pending DS-9 application and moves it into the approval queue. Total processing time from IID certificate receipt to restricted license mailing: 7-10 business days.
If you wait until after restricted license approval to schedule IID installation, you add 10-15 days to your timeline — the vendor won't prioritize your appointment because you're not driving yet, and DOL won't issue the restricted license without proof the device is already installed and monitored.

What Happens If You Install IID Before Filing the DS-9
Installing the device before submitting your restricted license application is legal and often faster. Washington does not require an active restricted license for IID installation — only proof that you intend to apply. The vendor accepts a copy of your DUI conviction or DOL suspension notice as eligibility documentation.
Once installed, the IID vendor reports the installation to DOL electronically within 24 hours. DOL's system logs the certificate under your driver license number. When you submit the DS-9 application days or weeks later, the IID requirement is already satisfied — DOL approves the restricted license without additional follow-up.
This sequence works best for drivers whose employer verification or SR-22 filing is delayed. You can lock in an IID installation slot while waiting for HR paperwork, then submit the full DS-9 packet once all components are ready. The IID certificate remains valid for 90 days from installation date — if you don't receive restricted license approval within that window, the vendor may require recertification.
How SR-22 Filing Timing Interacts With IID Scheduling
Washington DOL requires SR-22 proof of financial responsibility filing before restricted license approval. The SR-22 must be active and on file with DOL before they process your DS-9 application. Most non-standard carriers (Bristol West, Dairyland, GAINSCO, The General) file SR-22 electronically within 24-48 hours of policy binding.
If you schedule IID installation before securing SR-22 filing, the vendor will install the device — but DOL won't approve your restricted license until both the IID certificate and SR-22 filing appear in their system. The two requirements run in parallel, not sequentially. Coordinate with your insurance agent to bind the policy and confirm SR-22 filing the same week you book IID installation.
Some drivers attempt to use non-owner SR-22 policies while their vehicle is impounded or sold post-DUI. Washington allows non-owner SR-22 to satisfy the restricted license filing requirement, but the IID must still be installed in the vehicle you'll actually drive under the restriction — typically an employer's vehicle or a family member's car registered in Washington. The vehicle owner must consent in writing, and the IID vendor requires proof of that consent before scheduling installation.
What the $150 IID Installation Fee Covers and What It Doesn't
Washington IID vendors charge $150-$175 for initial installation, which includes the device hardware, calibration, vehicle integration testing, and the first month's monitoring fee. Monthly monitoring runs $75-$95 per month for the duration of your restricted license period and any additional IID compliance period ordered by the court.
The installation fee does not cover removal, recalibration after failed tests, or service calls for device malfunctions. If your vehicle's battery dies or you disconnect the IID without vendor authorization, expect a $75-$100 service call fee plus mandatory reporting to DOL — which can trigger restricted license suspension even if you had a legitimate reason for the disconnect.
Budget $150 installation + $85/month monitoring × restriction period in months. For a standard 1-year restricted license with 1-year IID compliance, total IID cost runs approximately $1,170-$1,290. This is separate from the $75 restricted license application fee, the $150 reinstatement fee due when your full license is restored, and the SR-22 premium increase — which typically adds $40-$70/month to your liability insurance cost.
How Employers React to Pre-Restricted-License IID Installation
If your restricted license is employer-purpose only and you'll be driving a company vehicle, the employer must consent to IID installation in their vehicle. Washington DOL requires employer signature on the Occupational License Statement confirming they understand the IID requirement and agree to permit the device in their vehicle.
Some employers refuse. Fleet insurance policies sometimes exclude drivers with IID requirements, and employers in transportation, delivery, or field service roles often interpret IID as unacceptable liability. If your employer declines to sign the statement, your restricted license application will be denied — no exceptions, no workarounds.
If the employer agrees, coordinate IID installation timing with their fleet manager. The vehicle will be out of service for 2-3 hours during installation. Some vendors offer mobile installation at the employer's location; others require you to bring the vehicle to their shop. Confirm the vendor's service radius before booking — if your employer is located outside the vendor's coverage area, you'll pay an additional $50-$100 travel fee or need to choose a different vendor.
