A second DUI in Colorado
Verified · next review
Ten days, and the program no longer buys them back. The state’s own summary of its drunk driving laws sets the second offense at ten days to a year with a fine of $600 to $1,500 and 48 to 120 hours of public service. What changes from the first is not only the numbers: the treatment route that suspends the mandatory minimum on a first conviction is not available in the same way here.
Written any number of ways — a 2nd DUI, a DUI 2nd, a 2nd offense DUI, or a second DUI in CO — and the paperwork will use none of them. Colorado charges it under a section number, and that is what decides the range below.
Grade. Misdemeanor
Confinement. 10 days to 1 year
Fine. $600 to $1,500

The device is a separate track
Colorado uses the interlock for early reinstatement: instead of sitting out a revocation, you fit a device and drive from the first day the action goes active. What you trade is time on the device — nine months at a lower reading, two years above 0.15% or after a refusal.
In Colorado the interlock term runs 9 months and is administered by Colorado DMV (Department of Revenue) — which is why a plea that settles the criminal case does not settle the device. What counts as a violation on it, and what an agency adds to the term, is its own arithmetic: violations and lockouts. Getting it off at the end is a procedure of its own too — removal and waivers.
Colorado DUI questions
Is there a 2nd DUI in Colorado with no jail time?
The state’s own summary of its drunk driving laws sets the second offense at ten days to a year with a fine of $600 to $1,500 and 48 to 120 hours of public service. What changes from the first is not only the numbers: the treatment route that suspends the mandatory minimum on a first conviction is not available in the same way here.
How likely is jail time for a second DUI in CO?
Start from what the statute forces and what it leaves to the judge. The floor here is 10 days to 1 year. Everything above that floor is argued, and the same conviction can end up served in custody, on work release or as a condition of probation depending on the county and the judge. What no one can promise you is a sentence below the statutory minimum — that is not a question of persuasion.
What is the punishment range for a 2nd DUI in Colorado?
Misdemeanor: 10 days to 1 year, and a fine of $600 to $1,500. The range is set by C.R.S. § 42-4-1307(4)–(5), and the figures on this page come from the statute rather than from a summary of it.
Does an interlock come with it in Colorado?
Colorado uses the interlock for early reinstatement: instead of sitting out a revocation, you fit a device and drive from the first day the action goes active. What you trade is time on the device — nine months at a lower reading, two years above 0.15% or after a refusal. The device requirement and the criminal penalty are separate tracks: one is handled by the court, the other by Colorado DMV (Department of Revenue).

Requesting a consultation connects you with an independent attorney or a legal referral service, who decide separately whether to take your case.
