Understanding ignition interlock devices after a DUI

On Behalf of | Jun 11, 2024 | DUI

An ignition interlock device is an instrument that measures a driver’s breath alcohol content before allowing a vehicle to start. In Washington, this device is mandatory for individuals with certain DUI charges.

While inconvenient, consenting to install an IID often allows some people to regain their driving privileges.

Vehicle requirements

Many individuals with DUI misdemeanors must install an IID in any vehicle they will drive, including company cars. However, it is possible to submit an employer exemption form for vehicles used for more than simply commuting.

Installation process

To install an IID, individuals should find a manufacturer that sells state-approved devices by visiting the Washington State Patrol’s website. The manufacturer’s fees usually include professional installation. Once installed, the vendor will submit proof to local authorities.

Out-of-state installation

For individuals who no longer live in Washington but need to meet IID requirements or install an IID outside the state, they must submit an out-of-state verification form. This form allows company representatives to prove that they installed the device. They will also report any removal or malfunction of the device and the driver’s incident history.

Certificate of compliance

At the end of the IID period, individuals will receive a certificate of compliance from their IID vendor. This certificate verifies that they did not try to start the vehicle with a BAC of 0.04 or more, did not fail any retests and kept up with device maintenance.

Some individuals may be eligible for an IID medical exemption if they are physically unable to operate the device. This exemption allows them to earn day-for-day credit towards their IID requirement period. To apply, individuals must complete the required form and have their doctors complete the medical provider section, indicating the temporary or permanent nature of the exemption.
