Do I Have to Get an Interlock Device if I Don’t Own a Car?

If you’ve recently been convicted of a DUI and asked yourself, “Do I have to get an interlock device if I don’t own a car?”—you’re not alone. It’s a common and important question, and we’re here to help you understand the ignition interlock requirements for non-vehicle owners in your state.
Even if you don’t currently own a car, your ability to legally drive again may depend on installing a court-approved ignition interlock device (IID) in a vehicle you have access to.
Here’s what you need to know.
State Laws Still Require an Interlock—Even If You Don’t Own a Vehicle
All 50 states enforce state-specific ignition interlock laws that may still apply even if you don’t own a vehicle. If you want to maintain or restore your driving privileges, you may be required to install an IID in any vehicle you operate—whether it’s:
- A family member’s vehicle
- A leased or rented car
- A motorcycle or recreational vehicle
- Your employer’s work vehicle
Driving without meeting your interlock requirements—regardless of car ownership—could result in license suspension, impoundment, or additional penalties.
What If You Share or Borrow a Car?
Whether you share a car with your spouse or occasionally borrow someone else’s vehicle, you may still be required to install an IID before you’re allowed to drive legally. Many states mandate that:
- You cannot operate any vehicle without an installed interlock
- The vehicle owner must provide written consent
- Non-owner interlock installation may be required for each car you intend to drive
If you drive a company vehicle, some states require your employer to install an interlock device or file an exemption, depending on whether you’re driving commercially or for limited business use.
Installing an Interlock in Someone Else’s Car: What to Expect
Installing an ignition interlock device in a vehicle you don’t own involves a few extra steps, but it’s absolutely doable. Here’s how RoadGuard Interlock helps you through the process:
- Get the vehicle owner’s permission and explain the reason for installation
- Have the owner complete a Vehicle Owner’s Consent Form
- Attend the installation appointment together
- Educate all users of the car on how to use the ignition interlock device properly
Once installed, the device must be used every time the vehicle is operated—by anyone—so it’s essential to make sure all drivers understand how it works.
Can You Avoid Installation If You Don’t Plan to Drive?
In some states, you can apply for a waiver if you don’t plan to drive at all. Your DUI attorney can help you with the paperwork to delay or pause the requirement—but keep in mind:
- You won’t be able to drive any vehicle during this time
- If you choose to drive again in the future, you’ll still need to install an IID
- Renting or borrowing a vehicle without an interlock device could lead to a violation
While this option may temporarily delay your ignition interlock requirements, it does not permanently exempt you from compliance.
Avoid IID Violations—Don’t Try to Bypass the Device
Trying to cheat or bypass your ignition interlock device can land you in even deeper trouble. Online “hacks” or having someone else blow into the device may seem tempting, but the risk simply isn’t worth it.
Attempting to bypass your IID may result in:
- Immediate license suspension
- Fines and penalties
- Extended interlock program duration
- Possible criminal charges or court prosecution
Tampering with your ignition interlock device only adds more stress and cost to your journey—stay compliant and drive responsibly.
