What you need to register a car in D.C.

To register a car in Washington, D.C., you'll submit documents to the D.C. Department of Motor Vehicles (DMV) in person or by mail. The core requirement is proof that you own the vehicle, proof that you live in D.C., and a completed process form. The DMV will also inspect your vehicle before issuing a registration.

D.C. registration is tied to your D.C. driver's license or D.C. ID card — you must have one or the other before you can register. If you don't have a D.C. ID yet, you'll need to get one first, which requires a separate visit to the DMV.

Registration in D.C. costs money and renews every two years. The fee depends on your vehicle's weight and emissions classification. You'll also need to pass an emissions test at an approved testing station before you register, unless your vehicle is exempt.

Key Takeaways

  • You must have a valid D.C. driver's license or D.C. ID card before the DMV will register your vehicle.
  • Bring the vehicle's title or proof of ownership, proof of D.C. residency dated within the last 60 days, and a completed process for Registration (Form DL-43) to the DMV in person.
  • Your vehicle must pass an emissions test at a D.C.-approved station within 60 days before you register, unless it qualifies for an exemption such as model year 2025 and newer or 1975 and older.
  • Registration fees vary by vehicle weight and emissions type, and registration lasts two years from the issue date.
  • New registrations require an in-person visit for vehicle inspection, but you can renew by mail if you have a current D.C. registration.

Documents you'll need to bring

Bring your vehicle's title or proof of ownership — this is the document that shows you own the car. If you financed the vehicle, the lender's name may appear on the title; bring it anyway. If you don't have the title yet (for example, if you just bought the car and the paperwork is still in transit), ask the DMV what temporary documents they'll accept.

Bring proof of D.C. residency. The DMV accepts a utility bill, lease agreement, mortgage statement, or bank statement dated within the last 60 days. Your name must appear on the document. A driver's license or ID card alone is not enough — you need a separate residency document.

Bring your valid D.C. driver's license or D.C. ID card. If you have an out-of-state license, you cannot use it for D.C. registration. You'll need to get a D.C. license or ID first.

Bring the completed process for Registration (Form DL-43), which you can read from the D.C. DMV website or fill out at the DMV office. You'll also need your vehicle's Vehicle Identification Number (VIN), which is on the title and on a metal plate on the driver's side of the dashboard.

The emissions test requirement

Before you register, your vehicle must pass an emissions inspection at a D.C.-approved testing station. The test checks whether your vehicle's exhaust meets D.C. air quality standards. You must complete the test within 60 days before you submit your registration process to the DMV.

Some vehicles are exempt from emissions testing: vehicles model year 2025 and newer, vehicles that are model year 1975 and older, and certain electric or hybrid vehicles. If your vehicle is exempt, you don't need a test, but you may need to bring documentation of the exemption to the DMV.

The emissions test costs money — the fee varies by testing station but is typically $20 to $30. When you pass, the testing station will give you a receipt or certificate with a test number. Bring this to the DMV when you register. If you fail, you'll need to repair the vehicle and retest at another station.

You can find approved testing stations on the D.C. DMV website. Many are independent repair shops or service stations. Call ahead to confirm hours and whether they have same-day appointments.

Where to register and how long it takes

The D.C. DMV has one main office location in Washington, D.C. You can also register by mail if you're renewing an existing D.C. registration, but new registrations typically require an in-person visit so the DMV can inspect your vehicle.

In-person registration usually takes 30 to 60 minutes, depending on how busy the office is. The DMV does not take appointments for registration — you arrive and take a number. Arrive early in the day or on a weekday if possible, as wait times are often shorter.

By mail, registration takes longer because the DMV must receive your documents, process them, and mail your registration back to you. Plan for two to three weeks total. Mail your documents to the address listed on the D.C. DMV website, and include a check or money order for the registration fee.

If you're renewing a registration that's about to expire, you can renew by mail up to six months before the expiration date. This is faster than waiting until the last minute.

Registration fees and what affects the cost

D.C. registration fees are based on your vehicle's gross vehicle weight rating (GVWR) and its emissions classification. The GVWR is the maximum weight the vehicle is designed to carry, including passengers and cargo — it's listed on a label inside the driver's door frame and on the vehicle's title.

Vehicles are classified as either standard emissions or clean fuel. Most gasoline cars are standard emissions. Clean fuel vehicles (hybrids, electric vehicles, and some newer low-emission models) may have a lower registration fee. The DMV will determine your vehicle's classification based on the model year and engine type.

Registration lasts exactly two years from the issue date. You'll receive a registration card and a license plate (or a sticker to place on your existing plate if you're renewing). The registration card must be in your vehicle at all times while you drive.

If you're registering a vehicle you just bought

If you bought the car from a private seller, make sure the title is signed over to you before you go to the DMV. The seller must sign the back of the title and print their name. If the title is not signed, the DMV will not register the vehicle.

If you bought the car from a dealership, the dealership usually handles the paperwork and may even submit your registration process for you. Ask the dealership what documents they need from you and whether they'll handle the DMV visit. If they don't, you'll need to complete the registration yourself within a certain timeframe — check your purchase agreement.

If you financed the vehicle, the lender's name will appear on the title as a lienholder. This is normal and does not prevent you from registering. Bring the title as-is to the DMV.

If you're moving to D.C. from another state

If you already have a valid registration from another state, you have a grace period to register in D.C. — usually 30 days from the date you establish D.C. residency. After that, driving with an out-of-state registration is illegal in D.C.

You'll need to surrender your out-of-state registration and title when you register in D.C., or bring proof that you've applied to transfer the title. The DMV will tell you what documents they need. You may also need to get a D.C. driver's license or ID card before you register your vehicle.

Your out-of-state registration will not transfer — you'll receive a new D.C. registration and new D.C. license plates. Keep your old plates until the DMV issues new ones.

Frequently Asked Questions

Can I register a car if I don't have a D.C. driver's license yet?

No. You must have a valid D.C. driver's license or D.C. ID card before the DMV will register your vehicle. If you don't have one, visit the DMV to get a D.C. ID first. This requires a separate process and documents proving your identity and D.C. residency.

What happens if my vehicle fails the emissions test?

You cannot register until it passes. You'll need to repair the vehicle and retest at another approved station. Once it passes, bring the new test certificate to the DMV. There's no limit on how many times you can retest, but each test costs money.

Can I register a vehicle I'm buying from a private seller before the title is transferred to me?

No. The title must be in your name before you register. Make sure the seller signs the back of the title and gives it to you before you leave. If the title is still in the seller's name, the DMV will not register the vehicle.

How do I renew my D.C. registration?

You can renew by mail or in person at the DMV. By mail, send your current registration card, a check or money order for the renewal fee, and a completed renewal form to the address on the D.C. DMV website. In person, bring your registration card and payment to the DMV office. Renewal takes about two weeks by mail or 30 to 60 minutes in person.

What if I move to a different address in D.C. after I register?

You must update your registration with your new address. You can do this by mail or in person at the DMV. Bring your registration card, proof of your new address, and a completed change-of-address form. There is usually no fee for this update.
