Court fees, SR-22 filing, ignition interlock, and reinstatement add up to $2,800–$4,200 in year one. Here's the full cost breakdown and what you can control.
The Full Cost Stack: What You Pay to Get Back Behind the Wheel
A restricted license in Denver runs $2,800–$4,200 in the first year when you add court petition fees, DMV reinstatement, SR-22 premium, and ignition interlock device costs together. The largest variable is SR-22 insurance: clean-record drivers adding SR-22 pay $900–$1,400 annually, but a DUI with SR-22 pushes premiums to $2,200–$3,600 depending on carrier and coverage limits.
Colorado requires SR-22 filing for the entire duration of your restricted license period, typically 1–2 years post-DUI. The filing itself costs $15–$50 through your carrier, but the liability coverage behind it is where costs separate. Most drivers stay with their current carrier and accept a 70–150% rate increase. Non-standard carriers writing high-risk Colorado policies (The General, Dairyland, Direct Auto, Bristol West) often quote $600–$1,200 less annually for identical SR-22 coverage.
Ignition interlock adds $70–$120 monthly ($840–$1,440 annually) for device lease, calibration, and monitoring. Denver metro installers (LifeSafer, Smart Start, Intoxalock) charge $75–$100 installation, $2.50–$4.50 per day lease, and $60–$80 monthly calibration. Jefferson County and Arapahoe County courts may require longer IID periods than the statutory minimum, pushing total IID spend past $2,000 for some drivers.
Court petition fees for a restricted license run $100–$300 in Denver County depending on whether you file pro se or through an attorney. DMV reinstatement after suspension costs $95. If you hire a DUI attorney to handle the restricted license hearing, add $1,500–$3,000 to the total stack.
SR-22 Premium: The Biggest Variable and Where Most Drivers Overpay
SR-22 filing requires continuous liability coverage at Colorado minimum limits: 25/50/15 (25k per person, 50k per accident, 15k property damage). Your carrier files proof electronically with the Colorado DMV. If coverage lapses even one day, the DMV revokes your restricted license and extends your underlying suspension.
Most drivers call their existing carrier (State Farm, Allstate, Progressive) and accept the post-DUI rate increase without shopping. That increase averages 110–140% in Colorado. A driver paying $900/year pre-DUI jumps to $1,900–$2,200 post-DUI with the same carrier. Non-standard carriers underwrite DUI risk differently and often quote $1,200–$1,600 for the same SR-22 coverage because they specialize in high-risk filings.
The non-standard market in Colorado includes The General, Dairyland, Direct Auto, Bristol West, GAINSCO, and Acceptance. Not every carrier writes in every ZIP code. Denver and Aurora have the widest availability; rural Douglas County and El Paso County have fewer options. You need three quotes minimum to find the floor rate. The difference between highest and lowest quote on identical SR-22 coverage often exceeds $1,000 annually.
Some drivers without a vehicle assume they don't need SR-22. Colorado DMV still requires it. Non-owner SR-22 policies cost $300–$600 annually and satisfy the filing requirement without insuring a specific car. If you borrow a vehicle or use rideshare to get to work, non-owner SR-22 keeps your restricted license valid.

Ignition Interlock: Lease, Calibration, and Metro Installer Wait Times
Colorado requires ignition interlock for all DUI-related restricted licenses. The device prevents the engine from starting if it detects alcohol on your breath. You pay for installation, daily lease, monthly calibration, and monitoring reports sent to the DMV.
Metro Denver installers charge $75–$100 upfront installation. Daily lease runs $2.50–$4.50 ($75–$135/month). Monthly calibration and data download costs $60–$80. Total monthly carrying cost: $135–$215. Over a 12-month restricted license period, that's $1,620–$2,580. Courts often extend IID requirements to 24 months for high-BAC DUIs or repeat offenses, doubling the total.
Wait times for installation appointments in Denver run 7–14 days during high-volume periods (post-holiday enforcement sweeps, start of ski season). Jefferson County and Adams County courts require proof of installation before issuing the restricted license, which means you're paying for the device before you're legally allowed to drive. Some drivers schedule installation the week before their hardship hearing to avoid delay.
Violations reset the clock. If the device detects alcohol, records a failed retest, or you skip a calibration appointment, the state extends your IID requirement by 1–6 months. The most common mistake is starting the car in the morning without accounting for mouthwash, medication, or overnight BAC residual. A single failed start can cost you 60 additional IID days at $4/day.
Court Fees, Reinstatement, and Attorney Costs
Filing a restricted license petition in Denver County or Jefferson County costs $163 court filing fee. If the court requires a probation department review or alcohol evaluation before the hearing, add $75–$150. The DMV reinstatement fee after suspension is $95, paid separately when your restricted license is approved.
Most drivers file pro se and represent themselves at the hardship hearing. Colorado provides a standardized petition form (DR 2436) and employers can submit a letter confirming work hours and location. Approval rates for first-time DUI restricted licenses in metro Denver run 70–85% when employment documentation is complete and the driver has proof of SR-22 and IID installation.
Hiring a DUI attorney to handle the restricted license petition costs $1,500–$3,000 in Denver. Attorneys negotiate approval conditions, argue for wider travel windows (work + medical + childcare instead of work-only), and handle continuances if documentation is incomplete. For drivers with prior violations, multiple suspensions, or incomplete DUI classes, an attorney improves approval odds enough to justify the cost.
Total non-premium costs (court, reinstatement, attorney) range from $260 if you file yourself to $3,500+ with full legal representation. These are one-time costs. SR-22 and IID are recurring and dominate the total stack.
What You Can Control: Shopping SR-22 and Installer Comparison
You cannot control court fees or DMV reinstatement. You can control SR-22 premium by shopping the non-standard market before you file. Three quotes take 30 minutes and often save $900–$1,400 annually. Non-standard carriers do not appear on aggregator sites; you call directly or use a high-risk insurance broker.
IID costs vary by $40–$60 monthly depending on installer. LifeSafer, Smart Start, and Intoxalock all operate in Denver and offer identical devices under state certification. Monthly lease and calibration fees differ. Call all three, ask for the all-in monthly cost including calibration and monitoring, and choose the lowest. Over 12 months, the difference between a $140/month installer and an $180/month installer is $480.
Some courts allow you to satisfy IID requirements with a camera-based system instead of a hardwired interlock if you drive a leased vehicle or your employer's car and cannot modify it. Camera systems (SCRAM or BACtrack) cost $10–$15/day ($300–$450/month), which is higher than traditional IID but solves the installation problem. Confirm with your court before purchasing.
Budget for the realistic total. Most Denver drivers spend $2,800–$3,200 in year one if they shop SR-22 and use a mid-cost IID installer. Drivers who skip shopping or hire an attorney land closer to $4,000–$4,500. The cost is not optional, but the variance is.
