While an “insured vehicle” may include a friend or neighbor’s vehicle or a rental car, if the vehicle was available for regular use, it might be excluded. A “replacement” vehicle will probably be covered, but in some cases only under circumstances where the insured’s vehicle cannot be operated for some specific reason, such as a repair. Coverage might not follow anyone if the insured is driving a vehicle other than a “private passenger vehicle not owned and listed on the insured’s policy.” There really is no such thing as a standard auto policy anymore and coverage for non-owned autos will be different under some policies and non-existent under others.
Auto insurance will generally cover a driver from any state as long as he has the insured’s permission to operate the vehicle. However, this isn’t always the case. In all instances, when someone else operates the insured’s vehicle, the auto coverage and policy terms may vary greatly depending on the carrier and insurance options selected by the insured. That said, if an insured is driving a company/commercial vehicle which has Med Pay/PIP coverage, that coverage is usually primary over the driver’s personal auto policy, which will be secondary in terms of coverage. There are some exceptions.
Collision and comprehensive insurance are two optional types of auto insurance where your insurer pays for repairs to your vehicle. While there are other optional auto insurance coverages, liability, comprehensive, and collision are three of the most common. These coverages work hand-in-hand to repair or replace most of the damages to your car. It's important to know the difference, and make sure you're adequately covered.
