Certain factors must be considered in determining if an insured is covered when driving someone else’s vehicle, including the reasons for driving the vehicle, if the insured had permission or not, or if it was a rental or dealership loaner. In each case, the individual circumstances and state law involved will factor into the outcome, but another policy might be considered primary over the insured’s.
Regardless of the type of car you drive or where you drive it, by owning and operating a vehicle and driving it on public roads, your car is vulnerable to all types of losses and damages, both to yourself and to others on the road and their property. Though you’re probably most concerned with accidents, your vehicle can also be damaged by acts of weather such as falling tree limbs or monster-sized hail, vandalism or even invaded by creepy crawlers, especially if you park outside or on the street.
Insurers don't determine your actual cash value (ACV) settlement based on what you owe, but rather on what the car is worth just prior to the accident. Let's say you owe $20,000 on your new car, but it's only worth about $16,000. If your car is totaled, you might get a settlement check of $16,000 but still owe an additional $4,000 on your loan or lease.
In general, insurance coverage for an insured driving someone else’s vehicle is the coverage he carries for his own vehicle. The driver’s personal coverage will apply in most cases when driving a vehicle he does not own. This includes any uninsured motorist coverage he carries and the medical portions of his policy. The driver’s property damage coverage might carry over while driving another’s car as well, depending on the policy language, the respective limits of the two policies involved, and the facts. If a person drives his own vehicle without insurance, he should not expect that he is covered when driving someone else’s vehicle.
Therefore, a very basic and often incorrect answer to the wrong question is that auto liability coverage generally follows the driver, while auto physical damage coverage generally follows the vehicle. However, more often than not, you will be asking the wrong question. As long as a driver has the vehicle owner’s permission to operate the vehicle, the owner’s policy will provide coverage no matter who the driver is. The vehicle owner’s policy should cover injuries and property damage. However, exceptions do exist. In most cases, therefore, the right question to ask would be “Is there insurance coverage under these specific facts?”
Policies typically use vague language when referring to acts of terrorism, but they are generally insured by the comprehensive portion of your policy. For example, if there is an act of terror and you need to make a claim on your car, that can only be made if you have comprehensive coverage. Since some circumstances are out of our control, comprehensive insurance is certainly important to have in your policy.
