Any positive alcohol breath content above .025

Any skipped rolling re-test

Anything specified by your State authority

Driving another person’s vehicle without an IID installed
In Washington state, State you cannot wait out the Ignition Interlock requirement; it must be satisfied. You can install an Ignition Interlock Device (IID) on a family member’s vehicle or a friend’s vehicle that you’re borrowing, or you can buy a car. For a court requirement the judge may also choose to place you on a different form of alcohol monitoring like Smart Start’s IN-HOM™ SMART Mobile™.
In the state of Washington, DUI consequences are generally as follows:

First DUI penalty: One year with an Ignition Interlock Device installed.

Second DUI penalty: Mandatory jail time and arraignment. Within five days, you have to install an Ignition Interlock Device in your vehicle as a condition of your release. Then, you must complete five years with an IID installed.

Third+ DUI penalty: 10 years with an IID installed.

Additional consequences may be dictated by your judge, court, or Washington State authority.
Once you have scheduled your Ignition Interlock Device (IID) installation with Smart Start, you will need to bring the following to your IID installation appointment:

Vehicle registration OR a letter of permission from owner of vehicle to install the Ignition Interlock Device (IID)

Driver’s license

Secondary proof of identification
To obtain an Ignition Interlock License (IIL) in Washington State, follow these steps. This process is designed to allow individuals whose driving privileges have been suspended due to DUI or related offenses to drive legally with an Ignition Interlock Device (IID) installed in their vehicle:

Install an Ignition Interlock Device. You can find an Ignition Interlock installation center in Washington on our website!

Obtain proof of financial responsibility. Typically, this involves purchasing and filing a SR-22 form with the Washington State Department of Licensing (DOL), which is a certificate of financial responsibility that your insurance company files on your behalf.

Apply for the Ignition Interlock License. You can apply for an IIL restricted license by submitting an application to the Washington State Department of Licensing. The application may include your personal information, details about your vehicle and IID, and the SR-22 certificate.

Pay the required fees. There will be fees associated with the IIL application, IID installation, and monthly maintenance. Make sure to pay all necessary fees to both the DOL and your interlock device provider.

Wait for approval. Once your application is submitted along with all required documentation and fees, the DOL will review your application. If approved, you will receive your Ignition Interlock License, which allows you to drive legally with the IID installed.

Comply with license restrictions and requirements. With an IIL, you must drive vehicles equipped with an IID only. Additionally, you must comply with all terms set forth by the DOL, including regular IID data downloads and maintenance checks.

It’s important to stay in communication with the Washington State Department of Licensing throughout this process for any specific requirements or changes in legislation. Always check the latest guidelines and procedures on the DOL’s official website or with a legal professional to ensure compliance with current laws.
