Hawaii requires registration within 30 days of purchase or moving to the state
When you buy a vehicle in Hawaii or move there with one, you must register it with the Hawaii Department of Transportation. The state does not allow you to drive on public roads without current registration, even temporarily. Registration is handled through your local county's vehicle registration office, not through a single statewide location.
The process takes about two weeks if you submit documents in person and have everything in order. If you mail your process, add another week. You cannot complete registration entirely online — Hawaii requires an in-person visit or mail submission with original documents.
Key Takeaways
- You must register your vehicle within 30 days of purchase or arrival in Hawaii, and driving without registration is illegal.
- Registration happens at your county's vehicle registration office, not a state office, so the location depends on which island you live on.
- You will need the vehicle title, proof of ownership, proof of residency, and a completed process form.
- Registration costs vary by vehicle type and weight, and you must also purchase a safety inspection sticker before registration is complete.
Where to register your vehicle by county
Hawaii has four counties, each with its own vehicle registration office. You must register where you live, not where you bought the vehicle. If you move between islands, you must re-register in your new county.
| County | Islands Served | Office Location |
|---|---|---|
| Honolulu | Oahu | Honolulu District Court Building, 1111 Alakea Street, Honolulu |
| Hawaii | Big Island | Hilo and Kona locations; check hawaii.gov for current addresses |
| Maui | Maui, Molokai, Lanai | Wailuku and Kahului locations |
| Kauai | Kauai | Lihue District Court Building |
Hours vary by location and change seasonally. Call your county office before you go, or check the Hawaii Department of Transportation website for current hours. Many offices close for lunch and have limited evening hours.
Documents you need to bring
Bring originals, not copies. The registration office will not accept photocopies of your title or proof of ownership. If you are registering a new vehicle, bring the manufacturer's certificate of origin or the title from the dealer. If you are registering a used vehicle, bring the title signed by the previous owner.
You will also need proof that you live in Hawaii. A utility bill, lease, or mortgage statement dated within the last 60 days works. A driver's license with your current address is acceptable if it was issued recently. If your address on the title does not match your current address, bring both documents showing the change.
Complete the process form before you arrive. The form is called the "process for Vehicle Registration" and is available on your county's website or at the registration office. Filling it out ahead of time cuts your wait time significantly.
Safety inspection requirement before registration
Hawaii requires a safety inspection sticker before you can register. You must obtain this sticker from an authorized inspection station, not from the registration office. The inspection checks brakes, lights, horn, windshield wipers, and emissions (on some vehicles). The sticker costs between $15 and $20 depending on the station.
Inspection stations are private businesses licensed by the state. You can find them through the Hawaii Department of Transportation website or by searching "vehicle inspection station" plus your county name. Bring your vehicle title and proof of ownership to the inspection station. The inspection takes about 15 minutes. Once you pass, the station gives you the sticker to display on your windshield.
Bring the inspection sticker with you when you go to register. The registration office will not complete your registration without proof that you passed inspection.
Registration fees and what they cover
Registration fees depend on your vehicle's weight and type. Passenger cars typically cost between $60 and $100 for a two-year registration. Trucks and vans cost more. Motorcycles cost less. Hawaii issues registrations that are valid for two years, not one.
The registration fee covers your license plate and registration certificate. If you need a replacement plate because yours is damaged or lost, there is an additional fee of about $10 to $15. Personalized plates cost extra and require a separate request.
You must also pay for the safety inspection sticker separately, as described above. Some counties charge a small processing fee if you register by mail, usually $2 to $5.
Registering by mail if you cannot visit in person
You can mail your registration process if you cannot visit the office. Send the completed process form, your title, proof of residency, and a check for the registration fee to your county's vehicle registration office. Include a self-addressed stamped envelope so the office can return your registration certificate and license plate.
Mail registration takes three to four weeks. The office will not process your process until they receive the safety inspection sticker, so you must obtain that in person at an inspection station before you mail anything. Some counties allow you to mail the inspection sticker with your process; others require you to bring it in person after registration is approved.
Call your county office to confirm their mail-in process before you send documents. Procedures vary slightly between counties, and sending materials the wrong way can delay your registration by weeks.
Renewing your registration
Hawaii sends renewal notices by mail about 30 days before your registration expires. You can renew by mail, in person, or online through the Hawaii Department of Transportation website. Online renewal is the fastest option if your vehicle passed its most recent safety inspection and you have no outstanding violations.
Renewal by mail or online costs the same as initial registration. You do not need a new safety inspection sticker unless your current one has expired or your vehicle failed inspection in the past. If you renew online and your registration is approved, you will receive your new registration certificate by mail within two weeks.
Frequently Asked Questions
Can I drive my vehicle before registration is complete?
No. Hawaii law prohibits driving an unregistered vehicle on public roads. If you are stopped by police, you can be cited. If you are waiting for registration to be processed, keep your process receipt and safety inspection sticker in your vehicle to show you have applied.
What if my vehicle title is from another state?
You can register a vehicle with an out-of-state title in Hawaii. Bring the original title, proof of ownership, and proof of residency to the registration office. The office will issue you a Hawaii title and registration. This process takes slightly longer than registering a vehicle that already has a Hawaii title.
Do I need to register a vehicle I own but do not drive?
If the vehicle is parked on public property or on a street, yes. If it is stored on private property and never driven on public roads, registration is not required. However, if you plan to drive it at any point, you must register it before you do.
What happens if my registration expires?
Driving with an expired registration is illegal and can result in a fine. If your renewal notice does not arrive, contact your county registration office at least two weeks before your expiration date. You can renew online or by mail even if you miss the notice.
Can I transfer my license plate to a new vehicle?
Yes. When you register a new vehicle, you can request to keep your old plate if it is still valid. Bring both the old plate and the new vehicle's title to the registration office. There is no additional fee for transferring a plate.
