Less than half of the drivers required to install ignition interlock devices in their vehicles did so between 2018 and 2025 in Washington, despite $14.5 million in state spending to bolster compliance.

Why it matters

Ignition interlock devices are a key tool to prevent repeat drunk driving offenses, but low compliance rates undermine their effectiveness and raise concerns about public safety on Washington's roads.

The details

The ignition interlock mandate requires drivers convicted of DUIs to install the devices, which prevent a vehicle from starting if the driver's breath alcohol content exceeds a preset limit. However, state data shows that only 41% of eligible drivers actually complied with the requirement over the 7-year period.

  • The ignition interlock mandate has been in effect in Washington since 2018.
  • Between 2018 and 2025, the state spent $14.5 million to increase compliance with the requirement.
