Arizona takes drunk driving very seriously. If you get caught driving under the influence (DUI), you’ll likely have to use something called an Ignition Interlock Device (IID) in your car. This small machine helps make sure you’re not drinking before you drive. Let’s explore how these devices work and what you need to know if you have to use one.
What is an Ignition Interlock Device?
An IID is like a tiny breathalyzer for your car. It’s about the size of a cell phone and connects to your car’s ignition system. Before you can start your car, you have to blow into the device. If it detects alcohol on your breath, your car won’t start. This helps keep drunk drivers off the road and makes everyone safer.
When Do You Need an IID in Arizona?
In Arizona, you need an IID for pretty much any DUI conviction, even if it’s your first time. Here’s when you might need one:
- If you get a regular DUI (blood alcohol level of 0.08% or higher)
- If you get an “extreme” DUI (blood alcohol level of 0.15% or higher)
- If you get a “super extreme” DUI (blood alcohol level of 0.20% or higher)
- If you refuse to take a breath, blood, or urine test when pulled over
- If you’re caught driving with a suspended license due to a previous DUI
How Long Do You Have to Use an IID?
The time you need to use an IID depends on your offense:
- For a first-time regular DUI: 12 months
- For a first-time extreme DUI: 12 months
- For a first-time super extreme DUI: 18 months
- For a second regular DUI within 7 years: 12 months
- For a second extreme DUI within 7 years: 24 months
- For any third DUI within 7 years: 24 months
Getting Your IID Installed
Once you’re ordered to get an IID, you have 30 days to get it installed. Here’s what you need to do:
- Choose an approved IID provider. The Arizona Department of Transportation (ADOT) has a list of certified providers.
- Schedule an installation appointment.
- Bring your photo ID, vehicle registration, and proof of insurance to the appointment.
- Pay for the installation and monthly lease costs. This usually costs between $70 and $150 per month.
Using Your IID
Using an IID takes some getting used to. Here’s what you need to know:
- You’ll need to blow into the device every time you want to start your car.
- The device might ask you to blow again while you’re driving. This is called a “rolling retest.”
- If you fail a test or miss a retest, it gets recorded. Too many failures can lead to penalties.
- You’ll need to get your IID serviced every month to download the data and make sure it’s working correctly.
Case Study: Alex’s IID Experience
Let’s look at a real-life example to see how this works. We’ll call our example person Alex.
Alex was arrested for a first-time DUI with a blood alcohol level of 0.10%. Here’s what happened:
- Arrest and Conviction: Alex was arrested and later convicted of a regular DUI.
- Sentencing: The judge ordered Alex to install an IID for 12 months.
- Installation: Alex chose an approved provider and had the IID installed within 30 days.
- Learning Curve: At first, Alex found it awkward to use the IID, especially the rolling retests.
- Close Call: One morning, after using mouthwash, Alex almost failed a test. He learned to wait at least 15 minutes after eating or drinking anything before using the IID.
- Compliance: Alex made sure to get his device serviced monthly and never tried to drive without using it.
- Completion: After 12 months of clean tests, Alex was able to have the IID removed.
Alex’s case shows that while using an IID can be challenging, it’s possible to comply with the requirements and eventually get back to normal driving.
Consequences of Violations
If you don’t follow the rules with your IID, you can get in big trouble. Here are some things that can happen:
- You might have to use the IID for longer, up to an extra year.
- You could be charged with a crime, which can mean up to 6 months in jail and a $2,500 fine.
- You might lose your driving privileges completely.
The Future of IIDs in Arizona
Arizona’s tough IID laws seem to be working. Since the state started requiring IIDs for all DUI offenses in 2007, alcohol-related driving deaths have gone down by 46%. This shows that while IIDs can be inconvenient, they’re helping to save lives.
