Yes, you typically need to rent a vehicle. The rental rate rarely includes the mandatory liability coverage required by state law. You must provide proof of acceptable coverage through your personal auto policy, purchase it from the rental company, or rely on certain credit card benefits. Driving without proper coverage exposes you to significant financial risk for damages and injuries.
For example, in California, state law mandates that all drivers carry automobile liability insurance. As the original content notes, this "Automobile Liability and Property Damage Protection is not included in the rental rate." The customer must either have a personal policy that extends to rental cars or purchase the rental company's Additional Liability Insurance (ALI). This is a common model across the U.S., though minimum coverage requirements vary by state.
Your personal auto insurance policy often covers rental cars. Most comprehensive and collision policies extend to rental vehicles for personal use, providing similar coverage levels for your deductible and liability limits. However, you must confirm this with your insurer before renting. Business trips or renting certain vehicle types (like luxury cars or trucks) may not be covered. If you rely on this, bring your insurance card or a declaration page as proof.
Rental companies offer several insurance products. Common options include:
Many premium credit cards offer primary or secondary rental car collision coverage as a cardholder benefit. Primary coverage pays for damage before your personal auto insurance, avoiding a claim on your policy. Secondary coverage only pays costs your primary insurance doesn't cover, like your deductible. This benefit usually applies only when you decline the rental company's LDW/CDW and pay for the entire rental with that card. Terms vary greatly, so review your card's guide to benefits.
The core risk of declining all coverage is assuming full financial liability. If you cause an accident without sufficient liability insurance, you could be personally sued for medical bills and property damage you caused to others. Without collision coverage, you are responsible for the full value of the damaged or stolen rental vehicle. Relying solely on credit card coverage requires understanding its precise terms, as it typically never includes vital liability coverage.

As someone who rents cars for work trips every month, my rule is simple: I never buy the rental company's extra . My own auto policy back home covers me, and my corporate credit card provides primary collision coverage. I always carry a digital copy of my insurance card on my phone.
Before my first business rental, I called my insurance agent. She confirmed my liability, comprehensive, and collision coverage extends to rental cars for both business and leisure. That conversation saved me thousands. I politely decline all offers at the counter, knowing I’m already protected. The key is verifying your coverage in advance, not at the rental desk.

We learned this lesson the hard way on a family vacation. We assumed our card had us covered. When a shopping cart dented the door, we found out our card’s coverage was only secondary. We had to file a claim through our personal insurance, pay the deductible, and our premiums went up at renewal.
Now, I research before every trip. I check my auto policy’s rental car clause and call my credit card company to ask three questions: Is it primary or secondary coverage? What vehicle types are excluded? What documentation do I need if I have a claim? For peace of mind with the kids in the car, I sometimes buy the rental company’s supplemental liability for the trip. It’s a small daily cost compared to potential disaster.

I’m a retiree who enjoys long road trips. I don’t own a car anymore, so I have no personal auto to fall back on. For me, purchasing the rental company’s insurance is non-negotiable and part of my travel budget.
I typically buy the Collision Damage Waiver and the Supplemental Liability Insurance. It makes the process seamless. If anything happens, I deal directly with the rental company. I don’t want to risk my savings or deal with complicated claims processes while I’m supposed to be relaxing. For infrequent renters without a personal policy, the rental coverage, while costly, provides essential and straightforward protection.

My perspective comes from frequently renting for both adventure travel and daily use. The “need” depends entirely on your existing assets. If you have a robust personal auto , you might only need to consider topping up liability limits. If you have a weak policy or none, you’re effectively insuring yourself.
Here’s my practical approach. First, know your state’s minimum liability requirements. Second, honestly assess your personal risk tolerance and finances. Could you afford a $40,000 bill to replace a totaled SUV? Or a $500,000 lawsuit? Third, dissect the rental agent’s offer. The Loss Damage Waiver is often the most expensive part. See if your credit card matches it. The liability insurance, however, is critical if you’re underinsured.
I mix and match. I use my credit card for damage waiver coverage and my personal policy for liability. On longer trips, I add the rental company’s supplemental liability for higher limits. It’s about building a tailored shield, not accepting or rejecting the offer outright.
