If you’re wondering whether you can drink alcohol if you have an Ignition Interlock Device (IID) installed in your vehicle, the answer is not as straightforward as you might think. At Smart Start, we receive many questions about drinking and driving, and the role that the IID plays in helping individuals who have been convicted of a DUI.
What is an IID and what does it do?
First, let’s talk about what an IID is and what it does. A Smart Start Ignition Interlock Device is a small device that is installed in a vehicle to prevent a driver from starting the engine if they have been drinking alcohol. The IID measures the alcohol level in the driver’s breath, and if it detects that the level is above the legal limit, the engine will not start. The IID also requires random retests while the vehicle is in operation to ensure that the driver does not consume alcohol while driving.
But can I still drink if I have an IID installed?
Now, back to the question at hand: can you drink alcohol with an IID installed in your vehicle? The short answer is maybe. The IID is designed to prevent a driver from operating a vehicle if they have been drinking, so you need to make sure all alcohol has left your system before you can drive again. You can read our blog about how long after drinking can you pass an Interlock test for more information. What are the consequences of drinking and driving with an IID?
If you are required to have an IID installed in your vehicle, it is important to understand that any consumption of alcohol can result in a violation of your IID program. A violation can have serious consequences, including an extension of your IID requirement, fines, and even the loss of your driving privileges.

Our goal is to help individuals who have been convicted of a DUI to regain their independence and their ability to drive safely.
