Does my car insurance provide coverage for a vacation rental car?

Yes. Most car insurance policies provide the same coverage for rental vehicles as provided for your own vehicles, for up to 30 days.  An additional coverage that may be needed is "loss-of-rents." This coverage allows the car rental company to recoup funds lost as a result of not being able to rent a car due to loss on your behalf.

What is the difference between collision and comprehensive coverage?

Collision covers accidental loss or damage to your vehicle because of a collision with an object or another vehicle or if the vehicle rolls over. Comprehensive covers losses named in the policy that are not collision losses. Examples of comprehensive losses include: vandalism, theft, fire and hail.

Does my auto insurance cover other drivers?

While policy language varies from company to company, auto insurance policies generally cover anyone you give permission to drive your vehicle. Normally all coverages remain in effect, regardless of the driver. Permission is automatically granted to all members of your household unless a driver is specifically excluded from your policy.
