Colorado License Plate Regulations
Colorado's DMV issued a genuine warning in June 2026 about a surge in fake temporary tags, the kind people print at home from unverified online sellers, and started actively pursuing impoundment, fines, and even jail time for drivers caught using them. That's not a hypothetical risk, it's happening right now, and it sits on top of a set of display and registration statutes most drivers have never actually read. Here's how the underlying law actually works.
Quick Answer: Which Statute Covers What
| Topic | Statute | What It Covers |
|---|---|---|
| Plate display | CRS 42-3-202 | Requires a valid, assigned plate in the correct location |
| Obscured or altered plates | CRS 42-3-204 | Bans covering or using a plate not assigned to your vehicle |
| Registration deadline | CRS 42-3-103 | 60 days from purchase to register |
| Temporary tag mounting | 1 CCR 204-10-34 | Must go in the permanent plate location, not the rear window |
| Plate theft and forgery | CRS 42-3-302 | Penalties for stealing, misusing, or faking a plate |
Governing Statutes and Display Rules
Colorado's core plate rules sit in a handful of specific statutes.
The Governing Display Statute
CRS 42-3-202 requires every vehicle to display a valid, assigned plate in the correct location, while CRS 42-3-204 separately bans obscured or altered plates and using a plate not assigned to that specific vehicle.
Obstructed Versus Altered Plates
Not quite. A plate covered by dirt, a trailer hitch, or a poorly placed accessory is typically a display violation under CRS 42-3-204, while an altered plate involving changed characters or added overlays falls under the more serious tampering provisions instead.
Registration Deadlines and Temporary Tags
These rules govern the gap between buying a vehicle and getting a permanent plate.
Registration Deadline for a New Purchase
60 days from purchase, under CRS 42-3-103. A temporary tag bridges that window, functioning as your registration while you gather title documents, secure insurance, and complete any required inspection.
Correct Temporary Tag Placement
Yes, and it's a common misconception. Dealers print the tag and mount it on a board in the same location where a permanent plate will eventually sit, under 1 CCR 204-10-34, not propped up inside the glass.
An Expiring Temporary Tag
Contact your dealership or county office before it runs out. Dealers can issue a second temporary tag under specific circumstances, generally when title delivery is still incomplete after 60 days despite the dealer's reasonable effort to process it.
Traffic Stops for an Expired Temp Tag
Yes. An expired temp tag is valid grounds for a stop on its own, and depending on how long it's been expired and whether registration is already underway, the outcome ranges from a warning to a formal citation.
CRS 42-3-205 and Temporary Plates
It specifically covers the requirement to properly display a temporary plate while permanent registration is being finalized, tying directly into the 60-day window set out elsewhere in state statute.
The 2026 Fraud Crackdown and Enforcement
Colorado has ramped up enforcement against fake tags while keeping the same federal privacy limits on plate data.
The 2026 Fake Tag Crackdown
Yes, actively, as of a June 2026 warning. The DMV's Motor Vehicle Investigation Unit flagged a surge in fraudulent print-at-home temporary tags bought from unverified online sellers, and confirmed drivers caught using them face vehicle impoundment, steep fines, and potential jail time.
Penalties for Theft or Forgery
CRS 42-3-302 covers theft, misuse, and fraudulent use of a plate. Altering serial numbers, fonts, or adding overlays that hide a plate's characters can trigger misdemeanor charges, while a genuinely counterfeit or forged plate is treated as a more serious offense entirely.
Legal Restrictions on Plate Lookups
Yes. The federal Driver's Privacy Protection Act, 18 U.S.C. Sections 2721 through 2725, limits what personal information tied to a plate can be released, and Colorado follows that federal framework exactly like every other state. A plate number alone doesn't entitle a member of the public to a registered owner's name or address.
Who Enforces These Rules
Local and state law enforcement handle roadside display, registration, and temporary tag violations, while county motor vehicle offices enforce compliance at registration, renewal, and title transactions, working with the DMV's Motor Vehicle Investigation Unit specifically on fraud cases.
Reporting a Suspected Fake Tag
Report it to local law enforcement or the DMV's Motor Vehicle Investigation Unit directly. The state has actively encouraged public reporting as part of its broader crackdown on this exact problem.
First-Time Versus Repeat Violations
No. Colorado generally treats repeated or intentional violations, knowingly using a counterfeit plate, for instance, more seriously than a first-time, unintentional display issue, which more often results in a warning or a smaller fine.
Electronic Insurance Verification
Increasingly, yes. Officers can check insurance status electronically during a stop rather than relying solely on a paper card, and registration renewal at the county level generally verifies current coverage as part of the transaction.
Other Grounds for Impoundment
Yes. Impoundment can also follow a lapsed registration combined with other violations, repeated display citations, or a vehicle that's otherwise unsafe or unlawfully operated, not solely fake tag fraud.
