比较不同信用卡的租车保险

用运通（Amex）和Visa卡租车，其保险是自动生效的，而且保险的金额和范围也比较大。万事达（MasterCard）不是所有种类的信用卡都有保险，而且保险的金额与范围稍差。

更详细的信息，需要看具体信用卡的 policy 条文。

Editor's note: This story, while accurate when published in 2008, has become outdated. See 2010 survey of credit card companies' rental car insurance policies.

If you're a veteran car renter, it's likely you routinely decline the rental company's offer of additional insurance coverage, smug in the knowledge that you're not wasting money. After all, if you get in an accident, your credit card will cover your deductible, right?

Maybe not. A closer look (chart) shows that credit card companies' policies vary sharply in who's covered, at what level, in which vehicles and where.

What credit card insurance does, doesn't cover
Most major credit cards come with a rental car loss and damage insurance plan. If you get in an accident while driving a rental, your auto insurance policy will likely pay most of the damage, but your credit card company provides secondary coverage. It covers whatever your primary auto insurance doesn't, paying whatever is left and going toward your deductible.

But there are requirements to qualify for additional coverage and limits to it.

In order for the benefit to kick in:

The rental car must be paid in full with the credit card that provides the insurance plan.
The cardholder must decline the auto rental company's collision waiver and be the primary renter of the car, though additional authorized drivers are also covered.

Credit card plans generally cover the repair or replacement of stolen or damaged rental vehicles. They also often include the charges of towing the vehicle to the nearest authorized collision repair facility. However, depending on the card's terms, the cardholder might be charged loss-of-use fees to cover the time when the damaged car is out of service during repair.

Coverage varies
Visa provides rental auto insurance to all cardholders as a free benefit. American Express offers it on all cards except the Delta Skymiles Options card; a paid upgrade to premium insurance is available too. Discover and MasterCard offer rental auto insurance only to cardholders at more elite levels, such as gold or platinum (in other words, those with better credit).Discover is the only issuer that doesn't offer loss-of-use coverage.

Most plans cover vehicles rented up to one month, and cover up to $50,000 of damage or loss (though American Express has plans that go higher). Be aware, however, that not all rental vehicles are covered. Commonly excluded vehicles are exotic cars, campers, pickup trucks and cargo vans and of course, limousins. Cars rented in certain countries are also excluded.

The accompanying chart outlines the basic auto rental insurance plans offered by the four payment networks. Details of auto rental insurance plans can change at any time and may differ slightly from issuer to issuer. Before you embark on a trip in a rental car, it is advisable to call your issuing bank (i.e., Chase or Capital One, not Visa or MasterCard) to gather the details on your individual plan.
