Renting a car can seem simple: reserve the vehicle, show a driver’s license, and decide whether to accept the protection offered at the counter. The insurance question is less straightforward because coverage may come from several sources, and each source protects against different risks.
For residents of Memphis, TN, the short answer is: you may already have some coverage, but you should confirm the details before declining rental-car protection. Your personal auto policy, credit card, renters insurance, health insurance, and the rental agreement may all play different roles.
Does Tennessee require insurance for a rental car?
Tennessee requires financial responsibility for vehicles operated on its roads. The state’s minimum liability limits are $25,000 for one person’s injury or death, $50,000 for injuries or deaths in one accident, and $25,000 for property damage.

That does not necessarily mean a renter must purchase a separate policy at the counter. A personal auto policy may provide liability coverage while driving a rental vehicle, but the policy’s terms control. A rental company may also offer liability protection as part of its optional products or may require renters to meet its own conditions.
The legal minimum is not the same as complete protection. If a serious crash causes injuries or extensive property damage, minimum limits can be used quickly. A renter should know both the amount of liability coverage available and whether the policy applies to the type of rental vehicle being used.
Does personal auto insurance cover a rental car?
Often, a personal auto policy extends coverage to a temporary replacement or rented vehicle, but this is not automatic for every policy or every situation. Coverage can depend on:
- Whether the rental is for personal use
- The type and size of vehicle
- The policy’s definition of a covered auto
- The length of the rental
- Whether the renter has liability, collision, and comprehensive coverage
- Exclusions for business use, moving trucks, luxury vehicles, or other specialty vehicles
If the personal policy includes collision coverage, it may help pay for damage to the rental car after a covered accident. Comprehensive coverage may apply to certain non-collision losses, such as theft, vandalism, fire, or weather-related damage. The deductible usually follows the policy, meaning the renter may have to pay that amount before insurance contributes.
The Tennessee Department of Commerce and Insurance’s auto consumer guide specifically lists “If I rent a car, will my policy cover me?” as a question consumers should ask when reviewing their coverage.

What does the rental counter protection cover?
Rental companies commonly offer several separate products. They are not interchangeable.
Collision or loss damage waiver
A collision damage waiver, sometimes called a loss damage waiver, is generally a contract with the rental company rather than traditional auto insurance. It may waive the renter’s responsibility for damage or theft involving the rental vehicle, subject to exclusions and conditions.
This protection may be useful when a renter does not carry collision and comprehensive coverage, has a high deductible, or does not want a claim involving a personal auto policy. It may also address certain rental-company charges that a personal policy does not fully cover, such as loss-of-use charges, administrative fees, or diminished value. The exact agreement should be read carefully.
Supplemental liability protection
This may provide liability coverage above what comes from the renter’s personal auto policy or may serve as primary protection in some circumstances. It can matter for renters who have no personal auto insurance, carry low limits, or are concerned about a large claim.
Personal accident protection
This may help with medical expenses for the renter and passengers after a crash. Existing health insurance, medical-payments coverage, or other benefits may already address some of these costs, but exclusions and deductibles vary.
Personal effects protection
This generally concerns belongings stolen from or damaged inside the rental vehicle. A homeowners or renters policy may already cover personal property away from the residence, subject to limits, exclusions, and the policy deductible. Tennessee insurance guidance notes that renters policies often cover belongings outside the home, including items stolen from a vehicle.

Does a credit card cover rental-car damage?
Some credit cards provide rental-car collision or theft benefits, but the protection is governed by the card’s benefit guide—not by the fact that the reservation was paid with the card.
Important questions include:
- Is the cardholder required to pay the entire rental charge with that card?
- Must the renter decline the rental company’s collision waiver?
- Is coverage primary or secondary?
- Are certain vehicle types excluded?
- Is theft covered?
- Are administrative fees, towing, diminished value, or loss of use covered?
- Is there a maximum rental period?
- Must the cardholder report the incident within a specific number of days?
The National Association of Insurance Commissioners explains that credit-card rental benefits are often secondary, meaning they may pay only after other applicable insurance has been used. It recommends confirming the benefits directly with the card issuer before relying on them. ([content.naic.org](https://content.naic.org/consumer/auto-insurance.htm?utm_source=openai))
A credit card’s rental protection also usually does not replace liability insurance. It may protect the rental vehicle while leaving injuries or damage to another person’s property to the renter’s auto policy or the rental company’s liability option.
What if you do not own a car?
Someone who does not own a vehicle may have no personal auto policy to extend to a rental. A non-owner auto policy can provide liability protection for certain situations involving vehicles the policyholder does not own. It generally does not insure the rental vehicle itself for physical damage.
The NAIC notes that non-owner insurance may provide benefits beyond rental-car use, but renters should still determine whether they need separate protection for damage to the rental vehicle. ([content.naic.org](https://content.naic.org/consumer/auto-insurance.htm?utm_source=openai))
Without personal auto or credit-card protection, a renter may need to consider both liability coverage and a collision or loss damage waiver from the rental company.
What Memphis renters should check before driving away
Seasonal storms, heavy rain, road debris, and sudden changes in traffic conditions can increase the chance of vehicle damage during a rental period. A careful pickup inspection is useful regardless of which coverage is selected.
Before leaving the lot:
- Photograph or record existing scratches, dents, wheel damage, windshield chips, and interior issues.
- Confirm the return location, time, fuel requirements, and mileage terms.
- Ask whether another driver is covered and make sure that person is listed if required.
- Check whether the agreement restricts travel outside a particular area or state.
- Keep the rental agreement, inspection report, and proof of insurance accessible.
- Confirm the deductible and whether towing, roadside assistance, loss of use, or administrative fees are covered.
A frequent misunderstanding is that “full coverage” means everything is covered. That phrase is informal and can conceal major differences in deductibles, exclusions, liability limits, and claim procedures.
When is buying the rental company’s protection more reasonable?
Purchasing additional protection may be worth considering when the renter has no personal auto insurance, carries only liability coverage, has a high deductible, relies on uncertain credit-card benefits, or wants to avoid submitting a claim under a personal policy.
Declining it may be reasonable when the renter has confirmed that a personal auto policy and credit-card benefit work together, the rental vehicle qualifies, the liability limits are adequate, and the renter understands the remaining deductible and exclusions.
The best decision depends on the specific policy documents and rental agreement—not simply on whether the renter owns a vehicle or has used the same card before.
