Proof of insurance

Evidence that a vehicle meets the state's insurance requirement, usually a paper or digital ID card shown at stops, crashes and registration.

Also called: evidence of insurance, insurance verification, proof of coverage

Proof of insurance is whatever your state accepts as evidence that a vehicle is insured to at least the legal minimum. For most drivers it is the Insurance ID card the insurer issues, showing the company, policy number, effective and expiration dates, and the covered vehicle. Most states also accept an electronic card displayed on a phone.

You may be asked for it at a traffic stop, after a crash, when registering a car or renewing plates, and sometimes at an inspection or in court. Many states also verify coverage electronically: insurers report policies to the motor vehicle agency, which can flag a registered car with no insurance on file. Drivers who must prove future financial responsibility after a serious offense, such as a DUI, need a state filing like the SR-22 rather than just a card.

Failing to show proof is not the same as being uninsured. In many states, a driver who was insured but could not show proof at a stop can have the ticket dismissed or reduced by bringing proof to court, though fees may apply. Driving with no insurance at all brings fines, suspensions and, in some states, limits on suing after a crash. Keep a current card in the car or on your phone.
