No, you generally cannot legally tax a car (often referred to as registering or titling a vehicle in the US) without providing proof of insurance. This is a standard requirement across nearly all states to ensure all vehicles on the road meet minimum financial responsibility laws. The process is designed to verify insurance coverage simultaneously with registration to prevent uninsured driving.
When you go to your local Department of Motor Vehicles (DMV) or equivalent agency, you will be required to present documentation before you can pay your registration fees and receive your new license plates and tags. This documentation almost always includes proof of insurance. This proof is typically a physical or digital document from your insurance company, called an insurance card or binder, that shows your policy is active and meets your state's minimum liability coverage requirements.
The specific requirements can vary by state. Some states have electronic verification systems that allow your insurance company to confirm coverage directly with the DMV, but you still need to have an active policy in place. Attempting to register a car without insurance is not only impossible through official channels but also illegal. Driving an unregistered vehicle can result in significant fines, penalties, and even the impoundment of your car.

| Ohio | Requires proof of financial responsibility, which is most commonly an insurance policy meeting state minimums. | |
| Florida | Mandatory to have Personal Injury Protection (PIP) and Property Damage Liability (PDL) insurance for registration. | |
If you have purchased a new car, you usually have a short grace period (often tied to the temporary tag from the dealer) to set up your own insurance policy and complete the full registration. However, the car is still covered under a dealer's policy or your existing policy during this time. The bottom line is that having valid auto insurance is a non-negotiable prerequisite for making your car legal to drive on public roads.
