Most states require proof of insurance that meets minimum coverage requirements before you can register your vehicle. This applies in 43 states and Washington, D.C.
If you've recently moved, check local requirements, as they vary. Many states use electronic verification systems that instantly confirm your coverage during registration. Without insurance, registration will likely be denied.
Even after registration, the DMV may monitor your car insurance status. If your policy is canceled or lapses, your registration could be suspended, even if previously approved.
