The Device Timeline Runs Before License Approval
You received Colorado's DUI suspension letter, researched Early Reinstatement online, found an approved IID vendor, scheduled installation for next week, and started the DMV paperwork assuming your two-year interlock requirement begins when the probationary license arrives. It doesn't. Colorado's ignition interlock mandate under C.R.S. § 42-2-132.5 begins the day the device is installed and activated — not the day DMV approves your Early Reinstatement application, not the day you receive probationary driving privileges, and not the day your formal suspension period ends.
Most drivers treat IID installation as the final step before approval. The structural reality: installation starts the clock. If you install the device on January 15 but DMV doesn't approve your Early Reinstatement until February 10, you've already burned 26 days of your mandatory two-year interlock period while waiting for paperwork clearance. The approval timeline and the device timeline are separate tracks — one controlled by DMV processing speed, the other controlled by your vendor's activation date.

730 days
First-offense DUI triggers a mandatory two-year ignition interlock requirement under C.R.S. § 42-2-132.5. Persistent drunk driver designation (two or more alcohol offenses) extends the mandate. The 730-day count begins at device installation and activation, not at license reinstatement approval.

Why the Interlock Clock Starts at Installation
Colorado's Early Reinstatement program is built around ignition interlock compliance monitoring, not traditional hardship-license route restrictions. The statute requires proof of IID installation as a condition of applying for probationary privileges. DMV treats the device as the enforcement mechanism: if the interlock logs clean for two years, you've completed the mandate. If you violate — failed start attempt, tamper alert, missed rolling retest — the two-year clock can reset or extend depending on violation severity.
Because compliance monitoring depends on device data, the mandate period must align with device operation dates. DMV cannot count interlock compliance days before the device exists. Installation activates the logging system; activation starts the mandate clock. Your formal suspension period (typically nine months administrative for first-offense BAC failure under Express Consent law, C.R.S. § 42-2-126) runs concurrently but independently — it's the period during which you cannot drive without Early Reinstatement approval, not the period during which interlock is required.
This creates the mismatch most applicants miss: you can satisfy your nine-month administrative suspension and still have 15 months of interlock mandate remaining if you installed the device late in your suspension window. The suspension lifts; the interlock stays. You regain unrestricted driving eligibility only after both timelines close.
Installing your IID two months into suspension means you'll drive with the device for two years after your nine-month suspension formally ends — the mandate clock doesn't care when your suspension lifts.
How Early Reinstatement Approval and Device Activation Interact
Step one: you contact a Colorado-approved IID vendor (Intoxalock, LifeSafer, Smart Start, and others hold state approval) and schedule installation. The vendor installs the device, activates monitoring, and electronically files Form DR-2870 (Ignition Interlock Device Installation Certificate) with Colorado DMV. That filing date is your IID mandate start date. Step two: you submit Early Reinstatement application documents to DMV — SR-22 proof of insurance, IID certificate confirmation, $95 reinstatement fee, and any court-ordered documentation if your suspension includes a criminal DUI conviction beyond the administrative Express Consent suspension.
DMV processing takes 10 to 20 business days after complete application receipt, but many applicants wait longer because they submit incomplete packets. The most common gap: SR-22 filing has not cleared DMV's system when the application arrives. Carriers file SR-22 electronically but the state database updates lag by 3 to 7 business days. If your Early Reinstatement packet arrives before the SR-22 posts, DMV sends a deficiency notice and your application sits in pending status until you resubmit proof. During that wait, your IID is active and logging compliance data — the mandate clock runs whether DMV has approved probationary driving privileges or not.

Persistent Drunk Driver Designation Extends the Mandate
Colorado designates drivers with two or more alcohol-related driving offenses (DUI, DWAI, or out-of-state equivalent) as persistent drunk drivers under state statute. That designation triggers a mandatory two-year IID requirement for any driving privileges during the revocation period, same as first offenders — but it also extends post-reinstatement monitoring. Persistent drunk drivers must maintain ignition interlock for two years after full license reinstatement, not just during the restricted Early Reinstatement phase.
If you fall under persistent drunk driver rules, your total interlock obligation spans the entire revocation period plus two years post-reinstatement. A second-offense DUI typically triggers a one-year revocation; Early Reinstatement allows restricted driving after a short waiting period, but you'll drive with the device for three years minimum — one year restricted plus two years unrestricted. The mandate clock still starts at installation, so delays in applying for Early Reinstatement extend the tail end of your obligation, not the front.
The distinction matters for cost planning. At $80 to $150 per month for device lease, monitoring, and calibration appointments, a two-year first-offense mandate costs $1,920 to $3,600 total. Persistent drunk driver designation pushes that to $2,880 to $5,400 over three years. Installation delays don't reduce those figures — they shift when the mandate ends, potentially overlapping with employment changes, vehicle purchases, or out-of-state moves that complicate device transfer.
Colorado Early Reinstatement Fee
$95
One-time administrative fee paid to Colorado DMV at application. Does not include IID installation deposit (typically $100 to $150), monthly device lease ($60 to $100), calibration visits ($10 to $20 each), or SR-22 insurance premium increase. Total first-month cost to activate Early Reinstatement commonly exceeds $450.

SR-22 Requirement Overlaps the Interlock Period
Colorado requires SR-22 continuous insurance certification for three years following DUI conviction, measured from conviction date under C.R.S. § 42-7-403. The SR-22 period and the IID mandate period overlap but do not align. If your conviction date is March 1, 2025, your SR-22 obligation runs through February 28, 2028 regardless of when you installed the interlock device or when DMV approved Early Reinstatement. If you installed your IID on May 1, 2025 (two months post-conviction), your interlock mandate runs through April 30, 2027 — eight months before SR-22 ends.
This mismatch creates a compliance window where you're driving without the device but still required to maintain SR-22 insurance. Letting SR-22 lapse during that window triggers automatic suspension under Colorado's electronic insurance reporting system. Most drivers assume SR-22 and interlock end together; they don't. Budget for SR-22 premium increases ($30 to $80 per month depending on carrier and violation history) to continue beyond your final IID calibration appointment.
Install Early to Close the Timeline Faster
You control one variable in this process: installation timing. Colorado allows IID installation before Early Reinstatement approval — you're not required to wait for DMV paperwork clearance to schedule the vendor appointment. Installing the device within 10 days of receiving your suspension notice starts the two-year mandate clock immediately and ensures that clock runs concurrently with as much of your administrative suspension period as possible. Waiting until month six of a nine-month suspension to install means you'll drive restricted for three months, then drive with the device unrestricted for 21 months after your formal suspension ends.
The path forward: contact a Colorado-approved IID vendor the same week you receive suspension notice, schedule installation within 10 business days, collect the DR-2870 certificate from the vendor immediately after activation, and submit your Early Reinstatement application packet (SR-22 proof, IID certificate, $95 fee, any court documents) to Colorado DMV the day after your SR-22 filing clears the state database. Early installation doesn't reduce your total interlock obligation — it compresses the timeline so the mandate closes closer to the end of your formal suspension rather than years after.
