To register a car in the U.S., you typically need your driver's license, the vehicle's title signed over to you, proof of insurance meeting your state's minimum requirements, a completed application for title/registration, and payment for fees. You must also pass a smog or emissions test and a vehicle safety inspection if required by your state. The process is handled at your local Department of Motor Vehicles (DMV) or a similar state agency. The most common mistake is showing up without the correct paperwork, so it's best to check your specific state's DMV website beforehand.
The exact requirements vary significantly by state, but the core documents are consistent. The title is your proof of ownership, and it must be properly assigned by the previous owner. Your proof of insurance must be valid and active on the day you register the vehicle. Fees often include sales tax, title fees, and registration fees, which can be a few hundred dollars depending on the car's value and your location.
| Common Document/Requirement | Description | State Variability (Example) |
|---|---|---|
| Driver's License | Proof of identity and state residency. | Required in all states. |
| Vehicle Title | Legal proof of ownership. | Must be signed by seller; electronic titles are common. |
| Proof of Insurance | Minimum liability coverage as mandated by the state. | Minimum coverage amounts vary (e.g., California vs. Florida). |
| Odometer Reading | Disclosure of the vehicle's mileage at the time of sale. | Required for most passenger vehicles. |
| Smog/Emissions Certificate | Proof the vehicle passes state air quality standards. | Not required in all states (e.g., many rural states). |
| Vehicle Identification Number (VIN) Inspection | Verification that the VIN on the car matches the title. | Often required for out-of-state vehicles or first-time registrations. |
| Sales Tax | Tax paid on the purchase price of the vehicle. | Rate varies by state and sometimes by county. |
| Bill of Sale | Document outlining the terms of the sale, including price. | Not always mandatory but highly recommended for record-keeping. |
If you're buying from a dealership, they often handle the registration paperwork for you, bundling the fees into your financing. For private sales, you are responsible for completing the process yourself. Always contact your local DMV or visit their website for the most accurate and up-to-date checklist.

Just went through this. It’s all about the paperwork. Don’t forget the signed title from the seller—that’s the big one. You’ll need your license, current insurance card, and a completed application. Call your insurance company to add the new car before you go to the DMV. Be ready to pay the registration and sales tax. Check online if your state requires a smog check; mine did, and it saved me a second trip.
