Driving with expired tags in Colorado is a class B traffic infraction, punishable by a fine of up to $100. On top of any ticket, renewing late adds a separate penalty of $25 per month for passenger vehicles, capped at $100. Colorado gives you a one-month grace period after your registration expires before those late fees start, but an officer can still pull you over and cite you during that window.
The One-Month Grace Period Only Covers Late Fees
Your registration expires on the last day of the month printed on your receipt and validation tabs. You then get one additional grace month before late fees begin accruing. If your tags expire December 31, January is the grace month, and late fees start February 1.1Department of Revenue – Motor Vehicle. FAQs – Registration
Here’s the catch that trips people up: that grace month applies only to the DMV’s late fees. It does not make it legal to drive. Colorado law requires current registration on any vehicle operated on public roads, and driving on expired tags is a citable offense the day after expiration.2Justia.

What the Ticket Costs
Expired registration is a class B traffic infraction. The statutory penalty range is $15 to $100.3Justia. Colorado Code 42-4-1701 – Penalties In practice the base fine often falls in the $75 to $100 range, and court surcharges push the total higher. Denver has issued $95 fines during enforcement pushes on expired registrations.
The bigger risk is what else the stop turns up. If your tags are expired and you also can’t show proof of insurance, or you’re behind on emissions, each violation stacks separately. A stop that started as a $75 problem can end in several hundred dollars of combined penalties.
When registration has been expired for months, officers may impound the vehicle. Towing and daily storage charges accumulate until you retrieve it, on top of the fines and the renewal itself.
Late Fees at Renewal
Once the grace month ends, late fees run $25 per month, or any portion of a month, for passenger vehicles. Trailers are $10 per month. The total caps at $100 per vehicle no matter how far behind you fall.1Department of Revenue – Motor Vehicle. FAQs – Registration
These late fees are entirely separate from any traffic citation. You pay them at renewal, in addition to your regular registration taxes and fees. So if you get pulled over three months past expiration, you’re looking at the citation fine, court surcharges, and up to $75 in accumulated late fees when you renew.
Temporary tags work the same way now. A 2023 change removed the exemption that had shielded expired temp tags from late fees, so if your dealer is slow with the paperwork, get a second temporary tag from the dealer or your county motor vehicle office before the first one expires.4Department of Revenue – Motor Vehicle.

How to Renew Right Now
Four options, from fastest to slowest.
Online
The myDMV portal at dmv.colorado.gov handles most standard renewals. You’ll need your plate number, current insurance on file with the state, and, if your county requires it, a current emissions record on file. Pay by credit card or electronic check. You get a temporary registration receipt immediately, and the new tabs arrive by mail.5Department of Revenue. Online Vehicle Registration Renewal FAQs
Self-Service Kiosks
Colorado MV Express Kiosks sit in King Soopers, City Market, and Safeway stores, along with some county offices. Scan the renewal notice or enter your plate number and the last eight digits of your VIN, pay, and print your tabs on the spot. The service fee is $3.50 at DMV-location kiosks and $4.50 at grocery stores, plus a 2.3% card surcharge or $0.50 for a check.6Department of Revenue – Motor Vehicle. Kiosks

In-person renewal during business hours, tabs printed while you wait. This is the route for anything unusual: a title issue, a vehicle update, or a case where the online system won’t accept your renewal.
Mail-In
Instructions come with your renewal notice. Processing can take weeks. If you’re already close to expiration, pick one of the faster options.
One practical note if you’re in the Denver metro area or Front Range: emissions testing is required before you can complete renewal in Adams, Arapahoe, Boulder, Broomfield, Denver, Douglas, Jefferson, Larimer, and Weld counties.7Colorado Department of Public Health and Environment. Emissions Inspections for Gasoline-Powered Vehicles A failed test that needs repairs can push you past the grace month, so don’t wait until the last week.
If You Already Got a Ticket
Read the citation first. Basic errors like a wrong plate number or wrong expiration date can be grounds for dismissal. To challenge the ticket, notify the county court listed on the citation by the response deadline, typically 30 to 90 days, and request a hearing.
Two defenses tend to work. The first is proof you already renewed before the ticket was written but the new tabs hadn’t arrived yet; a DMV receipt with the renewal date usually resolves it. The second is documentation that the vehicle was parked and not being driven at the time of the alleged violation.
If you renewed after the ticket but before your court date, bring proof of the current registration anyway. Judges have discretion to reduce or dismiss fines when a driver has come into compliance, particularly on a first offense.
Don’t Ignore the Citation
Skipping a traffic ticket is one of the more expensive mistakes available in Colorado. Under C.R.S. 42-4-1709, failing to respond or appear can lead to a default judgment where the court enters the maximum penalty without your input.8Justia. Colorado Code 42-4-1709
A judge can also issue a bench warrant for failure to appear, which means the next routine traffic stop turns into an arrest. Courts may refuse to let you renew registration until all outstanding fines are cleared, so you end up unable to legally drive until you’ve settled the original violation.
The Insurance Hit
The ticket isn’t the end of the cost. Auto insurers treat expired-registration citations as a violation on your driving record, and most add a premium surcharge that runs three to five years. The increase can run well over $100 per six-month policy period.
Add it up: a $75 fine, up to $100 in late fees, and a multi-year insurance surcharge can push the true cost of one lapsed registration toward $1,000. Renewing on time is genuinely the cheapest choice.
Points and Repeat Offenses
Expired registration itself does not add points to your Colorado driver’s license. But repeat noncompliance draws more stops, and those stops turn up other violations that do carry points. Twelve points within 12 months triggers license suspension.9Justia. Colorado Code 42-2-127
Chronic failure to register can also get the vehicle classified as unregistered and impounded. Between towing, storage, back late fees, and multiple citations, recovering the car can cost more than the car is worth. If you can’t afford to renew immediately, parking off public roads until you can is much cheaper than hoping to avoid a stop.
Active-Duty Military
Colorado waives late fees for active-duty service members whose vehicle registration and grace period expired while they were serving outside the state, provided the vehicle wasn’t driven on Colorado roads during that time. You’ll need military orders or other acceptable proof of out-of-state service. Service members stationed outside the United States may qualify for a full exemption from registration fees under C.R.S. 42-3-314, but the vehicle cannot be operated on any Colorado highway during the exemption period; driving it while exempt is itself a class B traffic infraction.10Colorado General Assembly.
