What term describes coverage for accidents occurring to an insured's vehicle that is not owned by that insured?

The correct answer is non-owned vehicle insurance. This type of coverage provides liability protection for accidents that occur while the insured is driving a vehicle that they do not own. It is crucial for individuals who may drive rental cars or borrow vehicles from friends and family, as it ensures that they are protected in case of an accident.

Non-owned vehicle insurance specifically addresses the gaps in coverage that may arise when an insured uses someone else's vehicle. It is designed to cover the insured's liability in case of damages or injuries caused while operating a vehicle that is not registered to them.

Other coverage types listed, such as comprehensive coverage, focus more on protecting against damage to the insured's own vehicle due to risks like theft or natural disasters, and liability coverage generally pertains to harm caused to others by the insured while driving their own vehicle. Assigned risk coverage relates to a program for high-risk drivers who cannot obtain insurance in the standard market, rather than covering non-owned vehicles. Therefore, non-owned vehicle insurance is the relevant term for the situation described in the question.
