You need a Colorado title and registration even if your car is already registered elsewhere

When you move to Colorado or buy a vehicle from another state, you cannot straightforward keep your old registration. Colorado law requires you to register any vehicle you own in the state within 90 days of establishing residency or purchasing the car, whichever comes first. This applies whether your vehicle is brand new, used, or already registered in another state.

The Colorado Department of Revenue, Division of Motor Vehicles (DMV) handles all vehicle registration. You will need to surrender your out-of-state title and registration, pass a vehicle inspection in most cases, and obtain a new Colorado title and registration. The process takes several weeks from start to finish, so plan ahead if you have a move date.

Key Takeaways

  • Colorado requires registration within 90 days of moving to the state or buying a vehicle, and you cannot legally drive on your old registration after that important date.
  • You must have a Colorado title before you can register; obtaining the title requires your out-of-state title, proof of ownership, and a vehicle inspection in most cases.
  • A vehicle inspection (emissions test for some vehicles, safety inspection for others) is mandatory unless your vehicle is brand new, a classic car, or exempt under specific rules.
  • The DMV processes title and registration applications by mail or in person at a local office, and processing times vary from two to six weeks depending on the method and current workload.
  • You will pay Colorado registration fees based on your vehicle's age and type, plus a one-time title fee, and these costs vary by county.

What documents you need to bring or mail

Start by gathering your out-of-state title, your proof of ownership (the title itself is the primary proof), and a government-issued photo ID showing your Colorado address. If you recently moved, a utility bill or lease dated within the last 60 days will work as proof of residency. If you bought the vehicle from a dealer, bring the bill of sale or Manufacturer's Certificate of Origin (MCO) if the vehicle is new.

You will also need proof of a passing vehicle inspection. Colorado requires either an emissions test (for vehicles in the Denver metro area and certain other regions) or a safety inspection (for vehicles outside those areas). Some vehicles are exempt: brand new vehicles with fewer than 7,500 miles, vehicles that are 24 years old or older, and vehicles registered as classic or antique. Check the DMV website or call your local office to confirm whether your vehicle needs an inspection before you schedule one.

If someone else is listed on the out-of-state title with you, both owners must sign the title process unless one owner has a notarized power of attorney. If the vehicle has a lien (a loan against it), bring documentation from your lender showing they consent to the title transfer.

Getting a vehicle inspection before you register

Colorado divides the state into emissions-testing regions and non-testing regions. If you live in the Denver metro area, parts of El Paso County, or a few other designated regions, your vehicle must pass an emissions test. Vehicles in all other areas need a safety inspection instead. You can find which region you are in on the Colorado Department of Public Health and Environment website.

Emissions tests are performed at authorized testing stations throughout the state; you can search for one near you on the state website. The test costs between $20 and $30 and takes about 15 minutes. A safety inspection is performed by any Colorado-licensed mechanic and typically costs $15 to $25. Both tests check different things—emissions tests measure what comes out of your tailpipe, while safety inspections check brakes, lights, windshield, and steering.

Once you pass the inspection, you will receive a certificate or report. Bring this with you when you explore for your title and registration. If you explore by mail, include a copy of the inspection report. Do not schedule an inspection until you are ready to explore for your title, because inspection certificates are valid for only 30 days.

explore for a Colorado title

You must obtain a Colorado title before you can register your vehicle. You can explore in person at any Colorado DMV office or by mail through the county clerk's office in the county where you live. The in-person route is faster if your paperwork is in order; the mail route takes longer but works if you cannot visit an office.

If you explore in person, bring your out-of-state title, proof of residency, your photo ID, the vehicle inspection report, and the title process form (Form MV-14). The DMV office will review your documents, collect the title fee (currently $20 for a standard title, though this can vary), and submit your process. Processing time is typically two to three weeks from the date you explore.

If you explore by mail, send the same documents to your county clerk's office along with a completed Form MV-14 and a check for the title fee. Include a self-addressed stamped envelope if you want the title mailed back to you. Mail applications take longer—usually four to six weeks—because they move through the county system before reaching the state DMV.

Registering your vehicle once you have the title

Once you receive your Colorado title, you can register your vehicle. You can register in person at a DMV office, by mail through the county clerk, or online through the Colorado DMV website if you meet certain conditions (your vehicle must have a Colorado title already, and you cannot be registering for the first time in Colorado).

Registration fees depend on your vehicle's age, type, and weight. A passenger car typically costs between $150 and $250 for the first year, but the exact amount varies by county. Trucks, SUVs, and motorcycles have different fee structures. You can estimate your fee on the DMV website by entering your vehicle information.

When you register, you will receive a registration certificate and license plates. Colorado plates are valid for one year from the month you register. After that, you renew annually by mail, online, or in person—you do not need to re-inspect unless the state or your county requires it for that renewal year.

Timeline and what to expect at each step

The entire process from start to finish typically takes four to eight weeks. Here is what the timeline usually looks like: Schedule and pass your vehicle inspection (1 to 2 weeks from when you decide to start). explore for your Colorado title in person or by mail (same day if in person, or mail it when ready). Wait for title processing (2 to 3 weeks if in person, 4 to 6 weeks if by mail). Once you receive the title, explore for registration (same day if in person, or mail it when ready). Wait for registration processing (1 to 2 weeks).

If you explore for both title and registration in person on the same day, you can sometimes complete both in one visit, though the registration certificate will still take time to arrive by mail. If you explore by mail, each step adds time because documents travel through the postal system and between county and state offices.

During this waiting period, you can legally drive on your out-of-state registration as long as you are within the 90-day window from when you moved or bought the vehicle. Once the 90 days are up, you must have a Colorado registration or you risk a citation. If your process is still processing when the important date approaches, bring your process receipt to a police officer to show you have applied in time.

Special situations: Vehicles with liens, salvage titles, or from other countries

If your vehicle has a loan against it, the lender holds a lien on the title. You will need written consent from the lender before Colorado will issue a new title. Contact your lender and ask them to send a lien release or consent letter directly to the Colorado DMV or to you. Some lenders handle this automatically when you notify them of the move; others require a written request.

If your out-of-state title is marked as salvage, rebuilt, or branded for any reason, Colorado will honor that brand. You cannot remove a salvage or rebuilt title in Colorado—it stays with the vehicle. Some branded vehicles cannot be registered for road use; check with the DMV before you move if your vehicle has a branded title.

If you are importing a vehicle from outside the United States, the process is more complex. You will need to clear U.S. Customs, obtain a Department of Homeland Security release, and provide documentation that the vehicle meets U.S. safety and emissions standards. Contact the Colorado DMV directly for guidance on imported vehicles, as requirements vary by country of origin and vehicle age.

Frequently Asked Questions

Can I drive on my out-of-state registration while I wait for my Colorado registration?

Yes, for 90 days from the date you moved to Colorado or bought the vehicle, whichever is later. After 90 days, you must have a Colorado registration or you can be cited. If your process is still processing, keep a copy of your process receipt in your vehicle as proof you applied on time.

Do I have to get new license plates, or can I keep my old ones?

You must get new Colorado plates. Colorado does not allow out-of-state plates on vehicles registered in the state. Your old plates should be returned to your previous state's DMV or kept as a souvenir, depending on that state's rules.

What if my out-of-state title is lost or I do not have it?

Contact the DMV in the state where the vehicle is currently registered and request a duplicate title. This can take several weeks. In the meantime, you can explore for a Colorado title using a bill of sale and other proof of ownership, but the state will issue a temporary title until your original title arrives.

Is there a way to register faster than waiting four to eight weeks?

explore in person at a DMV office is the fastest route for the title step. Some counties offer same-day or next-day processing if you explore early in the day and all your documents are correct. Call your local DMV office before you go to confirm they offer expedited service and what documents they need.

What happens if I miss the 90-day important date?

You can still register your vehicle, but you may face a late registration penalty. The penalty amount varies by county. It is better to register late than not to register at all, so explore as soon as you realize you have missed the important date.
