Planning a Long Road Trip with an Ignition Interlock Device
This blog is for general information only and is not legal advice. Always consult a qualified DUI or criminal defense attorney and your monitoring authority about your specific situation. If you’re convicted of a DUI and need to learn more about ignition interlocks, call our team at (888) 283-5899.
Taking a road trip with an ignition interlock device requires a little extra preparation, but the right planning helps you travel with confidence and stay compliant along the way.
Planning a road trip is always an exciting adventure, filled with the promise of new experiences and unforgettable memories. If you have an ignition interlock device (IID) installed in your vehicle, a little extra planning can help make sure your journey is smooth and stress-free. This guide discusses tips to help you navigate your trip with confidence.
1. Understand Your IID Requirements
Before hitting the road, review the rules that apply to your ignition interlock device. State laws vary, and those rules determine where and when you can drive. Nothing in this article describes the rules of any particular state, and it does not replace your court order, license documentation, or program guidelines.
Many drivers ask, “Can you drive out of state with an ignition interlock device?” The answer depends on your state’s requirements and the terms of your restricted license.
License Restrictions and Geographic Boundaries
Some drivers must follow specific license restrictions when using an ignition interlock device. Depending on your state or monitoring authority, your driving privileges may include limits on where or when you can drive.
Before planning a long trip, review the terms of your restricted license. Some drivers must stay within certain geographic boundaries or follow travel limitations tied to work, school, or medical needs. Understanding these restrictions can help you limit any potential violations on your journey.
These limitations also affect your ability to travel freely. Drivers often ask, “Can you drive anywhere with an IID?” In many cases, you may drive for approved purposes, but some restricted licenses limit travel.
If you plan to cross state lines, you may also need documentation verifying your ignition interlock status. Some states use forms, such as an Out-of-State Ignition Interlock Status Verification, to confirm your ignition interlock device meets program requirements.
If you have questions about your specific driving permissions, contact your monitoring authority or speak with an Intoxalock® State Specialist before traveling.
Sharing Responsibilities on the Road
If you travel with others, explain how your interlock works and what it requires. Make sure everyone understands the importance of following ignition interlock procedures, including random retests, during the trip.
Many drivers share driving responsibilities during long road trips. If someone else drives your vehicle, make a quick note on your phone, record a short video, or write down the time when others take the wheel.
You remain responsible for missed retests or positive results recorded by the device, even when someone else drives your vehicle. Keep a record of who drove the vehicle and when they provided breath samples. Clear records can help to answer questions if they arise later.
2. Regular Calibration
Make sure your IID is properly maintained and calibrated before you embark on your trip. Take advantage of early calibration if your state allows it and start your trip with peace of mind.
If your interlock program permits early or out-of-state calibration, you may be able to complete service while traveling. Check your specific program rules and confirm with Intoxalock before you rely on out-of-state service.

3. Prepare for Your Journey
Preparation makes traveling with an IID much easier. Plan your route, pack a few helpful supplies, and identify who to contact if questions arise. These steps can help reduce stress and keep your trip running smoothly, so you can focus on fun pit stops and the enjoyment of the drive.
Know Your Route
Mapping your route may make the journey smoother. Many free apps and tools can help create the ideal route for your trip. Be sure to scout nearby Intoxalock service center locations in case you need assistance with your device. You are likely less than 15 miles away from an Intoxalock location.
Pack Extra Mouthpieces For Your IID
Bring extra mouthpieces for your device to avoid sharing, especially if others will drive your vehicle. Mouthpieces are available for purchase at Intoxalock service centers or by emailing us a request at Help@Intoxalock.com.
Create a Contact List
Create a list of emergency contact numbers to keep in your glove box in case you cannot access your phone or cell service, including 24/7 roadside assistance specifically for interlock device issues.
Travel FAQs for Ignition Interlock Drivers
Can you drive out of state with an ignition interlock device?
In some cases, you may be allowed to travel out of state, but this depends on your state’s laws, the terms of your restricted license, and any court or monitoring-authority conditions. Most states allow drivers with an IID to travel out of state, as long as they continue to follow all program requirements.
Responsible use includes using the device for every trip, completing random retests when prompted, and maintaining scheduled calibrations. Before leaving the state, confirm your travel plans comply with the conditions of your ignition interlock program.
Can you travel for work with an IID?
You may be able to travel for work, depending on your court order, probation conditions, and license restrictions while using an ignition interlock device. The device allows you to operate a vehicle as long as you complete the required breath tests and follow all program requirements.
If your job requires frequent travel, plan ahead. Map nearby service center locations along your route and allow enough time for scheduled calibrations. Staying organized and following device instructions carefully can help keep work travel free of interruptions.
Can you travel to Canada with a DUI conviction?
Travel to Canada after a DUI conviction can be complicated. Canadian immigration law considers driving under the influence a serious offense, and individuals with a DUI may be denied entry.
Drivers with a DUI conviction should consult with an immigration attorney licensed in the relevant jurisdiction and review current guidance from the Government of Canada before attempting to travel. Some travelers may have potential options under Canadian law, depending on the circumstances and the amount of time that has passed since the conviction.
Can you travel while on probation for a DUI?
Travel may be possible while on probation, but requirements vary by jurisdiction and individual probation orders. Speak with your attorney or probation officer before making any travel plans.
Courts and probation officers may impose travel restrictions, especially if the probation order requires regular check-ins, alcohol monitoring, or participation in treatment programs. Obtaining permission in advance can help avoid violations and keep your probation in good standing.
Can you drive anywhere with an interlock?
In certain cases, drivers with an ignition interlock device can drive to approved locations such as work, school, medical appointments, and other necessary destinations. However, the exact rules depend on your state and the terms of your restricted license.
Some drivers can travel more freely, while others must follow specific geographic or purpose-based restrictions. If you are unsure about where you can drive, review your license conditions or speak with your monitoring authority before traveling.
Enjoy a Stress-free Journey
Traveling with an ignition interlock device does not have to take away from the experience of a road trip. The right preparation and a clear understanding of IID requirements can help you to focus on the destination and the joy of the drive ahead.
A few simple steps before you leave can help make the trip easier. Plan your route, pack the right supplies, and know where to find support if you need it.
