Rental car insurance

If you're looking to rent a car, depending on your needs and location, there are a number of alternatives—the traditional brick-and-mortar companies, peer-to-peer car services and car sharing programs—each with its own insurance parameters. It pays to understand your existing coverage first, and then look at your rental insurance options.

No matter what company or what kind of company you're renting from, the most important step is to read and understand the car rental or car sharing agreement. Most companies clearly state what is covered as well as the supplemental coverage that can be purchased. If you don't understand, have the rental or car sharing company representative walk you through.

If you're renting a car, check your own coverages first

Before you enter an agreement with any type of rental service, maximize use of the insurance you're already paying for and avoid paying for duplicate insurance.

If you own or lease a car and/or have homeowners insurance, call your insurer to first check the following:

• How much coverage you currently have on your own car – In most cases, whatever auto insurance and deductibles you have on your own car would apply when you rent a car (providing you are using the rental car for recreation and not for business).

• If you still have collision or comprehensive – If you dropped these coverages on your own car as a way to save money on your car insurance, you may not be covered if your rental car is stolen or damaged. Insurance rules vary by state, so it is best to check with your insurance professional for the specifics of your policy.

• If you are covered for administrative fees, loss of use or towing charges – Check to see whether your insurance company pays for—or provides a rider for—additional fees.

• Whether your homeowners or renters insurance covers the loss of possessions – These policies (not your car insurance) generally cover your belongings if they are damaged or stolen out of your vehicle.

The credit card you use to rent a car may also provide some insurance. Though coverage is likely to be limited—for example, it may only cover the deductible if you make a claim—it's worth knowing what protections it will provide.

• Know that benefits differ – Insurance coverage can depend on the company or bank that issues the card or even the level of card. For example, a platinum card may offer more robust coverage than a green card. If you have more than one card, you may want to compare what insurance they offer for car renters.

• Contact the credit card issuer to find out what they cover – If you are depending on a credit card for insurance protection, ask the company or bank that issued the card to send you their coverage information in writing.

• Credit card insurance benefits are usually secondary – That is, they will kick in after your personal insurance policy or the insurance coverage offered by the rental car company are utilized.

Insurance if you're renting from a brick-and-mortar car rental

Brick-and-mortar car rental companies are generally found at airports, train stations or other locations where travelers converge. These traditional rental companies allow you to simply reserve or select a vehicle from one of the many generally available on any given day. The insurance you'll be offered is fairly standard (though, like all car insurance, it varies by state).

Depending on what type of auto and/or homeowners insurance you carry, you may want to consider some of the insurance coverage provided by the rental car company. While auto insurance regulations, costs and coverage will vary by state and insurer, consumers renting from traditional companies can generally choose from the following coverages:

• Loss Damage Waiver (LDW) – Also referred to as a collision damage waiver, an LDW is not technically an insurance product—it is designed to relieve or “waive” renters of financial responsibility if their rental car is damaged or stolen. Waivers may also provide coverage for “loss of use,” in the event the rental car company charges for the time a damaged car cannot be used because it is being fixed, as well as towing and administrative fees. The LDW may become void if the accident was caused by speeding, driving on unpaved roads or driving while intoxicated. However, if you carry comprehensive and collision auto insurance, you may already be covered for damage to a rental car.

• Liability Insurance – By law, rental companies must provide the state required minimum amount of liability insurance coverage—often this does not provide enough protection. If you carry your own auto insurance and have opted for higher liability limits (which is recommended), you’ll be adequately covered. Non car-owners who are frequent renters have the option of purchasing a non-owner liability policy, which can provide the additional liability needed.

• Personal accident insurance – This covers the driver and passengers for medical and ambulance bills for injuries caused in a car crash. Whether or not you should consider this depends on your health insurance and the personal injury protection (PIP) provided by your auto insurance, which will likely cover medical expenses.

• Personal effects coverage–This provides insurance protection for the theft of items from a rental car. Consider this if you do not carry homeowners or renters insurance to cover this type of loss.

Insurance if you're using a car sharing service

With car sharing programs, for a monthly or annual membership fee, consumers can pick up a vehicle at a wide range of locations for periods ranging from minutes to days. These programs are popular in urban settings where owning a car can be expensive or difficult, but where it's convenient have a car available when it's needed. Coverage options vary widely, but there is usually some insurance included.

The insurance offered by these types of companies is not standardized so read the insurance coverage information carefully (it can usually be found on the service's website). If you have any questions, call the company's customer service line. And contact your auto insurer if you feel you need more information to make an educated insurance coverage decision.

• Car sharing programs (like ZipCar) generally include insurance costs in the fee. However, if the car is involved in a collision or is stolen, the renter may be billed for a specific dollar amount that is stated in the membership agreement. For an additional cost, customers can purchase a “waiver” to avoid paying the accident fee.

• Many car sharing programs limit coverage for young drivers to the minimum state required amount of liability. Renters under the age 21 should read the insurance coverage carefully. If it's not adequate to their needs, they can look into whether their parents’ auto insurance would cover them for the difference, or purchasing their own non-owner liability policy.

Insurance if you're renting from a peer-to-peer service

Peer-to-peer car rental networks enable consumers to rent personally owned cars from others. Insurance coverage varies widely, depending on location and service.

• Peer-to-peer rental services (like Turo) may offer a range of insurance options and, under some circumstances, the driver may decline coverage.
