Which of the following is NOT considered an uninsured vehicle?

An uninsured vehicle is typically defined as one that does not have valid insurance coverage as per the requirements of the law. In this context, a stolen vehicle is not considered an uninsured vehicle because it was originally insured before being stolen. The insurance policy remains in place; therefore, even though the vehicle is not in the owner's possession, it still holds the characteristics of an insured vehicle.

In contrast, an insured vehicle whose insurer denies coverage would be deemed uninsured for the purpose of a claim because the coverage was not available at the time of the incident. Similarly, a "hit and run" vehicle is classified as uninsured because the driver cannot be identified to hold accountable for insurance purposes. Finally, if an insured vehicle’s insurer becomes insolvent, the insurance is no longer valid, rendering that vehicle uninsured as well. These scenarios underscore the distinctions among types of vehicles when it comes to insurance coverage, confirming that the stolen vehicle stands apart from the others involved in the question.
