Summary: Two drivers can use the same interlock device in Colorado, making it more affordable for households sharing a vehicle after a DUI conviction. Both drivers must understand the device’s operation and follow proper testing procedures, as all breath samples are recorded under the restricted driver’s account. The person with the interlock restriction remains legally responsible for all test results, regardless of who was driving at the time. Pitstop Interlock offers comprehensive training for all household drivers, transparent pricing, and convenient service at multiple Colorado Springs locations to ensure successful compliance throughout your interlock requirement period.
Understanding Interlock Device Sharing in Colorado
Are you wondering if two drivers can use the same interlock device after receiving a DUI in Colorado? You’re not alone. Many Colorado drivers facing DUI convictions struggle with this exact question, especially when sharing a household vehicle with family members or partners.
You might be wondering about the practical aspects: Will the device recognize different users? What happens if the other driver consumes alcohol? How will the system know who is who? These concerns are perfectly valid, but don’t worry. Once you learn the nuances of interlock sharing, maintaining compliance will become a breeze. The confusion around interlock device sharing often leads to unnecessary stress, additional expenses, and potential compliance issues that could delay your return to unrestricted driving privileges.
Potential Challenges When Two Drivers Can Use the Same Interlock
While two drivers can use the same interlock device, this arrangement isn’t without potential complications. The biggest concern is accountability for breath sample results. Since the interlock device records all test results but doesn’t identify which driver provided each sample, any violations will be attributed to the person with the interlock restriction.
You must have complete confidence that anyone using your interlock-equipped vehicle understands the serious consequences of failed tests and will respect the zero-tolerance policy for alcohol consumption before driving. Some families find it helpful to establish clear rules and schedules for vehicle use, ensuring everyone knows when and how they can access the car while minimizing the risk of compliance issues.
Technical Considerations When Multiple People Use an Interlock
You must understand the technical aspects when two drivers can use the same interlock. Each authorized driver must learn the proper breath sample technique, including the correct blowing pattern and duration required for accurate readings, regardless of whether they have a restriction themselves or are simply sharing the vehicle with someone who does.
Temperature sensitivity represents another technical consideration when multiple drivers use the same interlock. During Colorado’s cold winter months, the device may require slightly longer warm-up times, which all drivers should be prepared for when planning their departures. Luckily, Pitstop Interlock’s Smart Start devices feature fast warm-up times and user-friendly interfaces, making them accessible even for drivers with no previous experience with interlock technology.
We also offer a 24/7 comprehensive support system to ensure that technical questions never become roadblocks to your successful program completion, giving you peace of mind throughout your interlock requirement period.

Legal Implications of Sharing an Interlock Device
The legal responsibility for interlock compliance ultimately rests with the restricted driver, regardless of who actually provided a problematic breath sample. When two drivers can use the same interlock device, the person with the court-ordered restriction remains accountable for all recorded violations. The Colorado DMV doesn’t distinguish between different users of the same device when reviewing compliance reports, so any violations could extend your restriction period or trigger additional penalties regardless of who was driving.
You need to know your specific court order or DMV requirements before establishing a shared interlock arrangement. Some restricted drivers may have specific limitations on who can operate their vehicles or additional monitoring requirements that could complicate sharing situations.
If you need help navigating these complex legal questions, Pitstop Interlock can provide clear information on your obligations and how they affect your ability to share an interlock device. Unlike other providers who leave you guessing about compliance, we take the time to ensure you fully understand your legal obligations and sharing arrangements.
Financial Considerations for Shared Interlock Devices
When two drivers can use the same interlock device, the financial benefits can be substantial compared. For households managing the financial impact of a DUI conviction, these savings can make a significant difference in overall program affordability, particularly during longer restriction periods.
Developing a fair cost-sharing arrangement between drivers can help make the financial burden more manageable for everyone involved. Some households choose to split the monthly lease payments proportionally based on vehicle usage, while others might have the restricted driver cover the device costs. Whatever arrangement you choose, having clear financial agreements in place before installation helps prevent misunderstandings or conflicts later.
