An Ignition Interlock Device (IID) prevents a vehicle from starting if it detects alcohol on the driver’s breath. The driver blows into the device, and if their breath alcohol content is below the programmed limit, the car will start. You’ll also have to complete periodic retests after starting your vehicle to ensure continued compliance. Learn more about how IIDs work with our complete guide.
