When you collect car hire in California, the counter agent may offer LDW (Loss Damage Waiver) or CDW (Collision Damage Waiver). These are not the same as traditional insurance, they are waivers that reduce what the rental company can charge you if the vehicle is damaged or stolen. Many travellers already have cover through a third-party policy, such as a standalone car hire excess policy, a credit card benefit, or travel insurance with rental car protection. The practical question is simple, what proof will the rental desk accept if you want to decline LDW/CDW, and how do you avoid being pressured into buying it anyway?
The key is understanding two things. First, in California, rental companies can sell optional damage waivers, but they do not have to accept your alternative cover as a substitute. Second, even when they do not require LDW/CDW, they may still require a security deposit and they will still hold you responsible for damage first, then you claim back from your insurer. Your proof is mainly for your own confidence, for speeding up any desk conversation, and for making sure you have the documents you would need if a claim happens.
If you are collecting at major hubs, the process can be fast paced. For location context, Hola Car Rentals has pages that describe pickup points and suppliers at places like Los Angeles Airport (LAX) and San Francisco Airport (SFO), where queues and upsell scripts are common. Being prepared helps you keep the discussion factual and brief.
LDW, CDW, and “third-party cover” in plain terms
LDW and CDW are umbrella terms used differently by different rental companies. Typically, they limit your financial exposure for damage to the rental vehicle, and sometimes theft, subject to exclusions. “Third-party cover” in this context usually means any protection you arranged independently that would reimburse you for the costs the rental company charges you, such as the excess, loss of use, towing, and admin fees. It may also refer to a liability policy, but note that liability (injury or property damage you cause to others) is separate from LDW/CDW and is handled differently in the US.
In California car hire, you should separate these decisions:
Vehicle damage and theft, often addressed by LDW/CDW at the desk, or by your own policy that reimburses you.
Third-party liability, typically provided at a basic level by the rental company as required, with optional top-ups. Your UK motor policy rarely extends to US rentals, and many credit card benefits do not cover liability.
This article focuses on proof for declining LDW/CDW, but always confirm your liability position too.
What counts as acceptable evidence to decline LDW/CDW
There is no single universal “accepted proof” standard across all California rental counters, because the waiver is optional and the desk is not obliged to validate your alternative cover. That said, the following documents are the most effective at demonstrating you understand your protection and can support your decision.
1) Insurance certificate or policy schedule naming the cover
The strongest document is a policy certificate or schedule that clearly states what is covered. For declining LDW/CDW, the desk conversation goes better when your document includes:
Your name, matching your driving licence and passport.
Cover type, such as “rental vehicle excess reimbursement”, “collision damage reimbursement”, or “damage to rental vehicle”.
Territory, explicitly including the United States, USA, or worldwide including USA and Canada.
Policy dates, showing it is valid during the rental period.
Benefit limit, high enough to cover common charge scenarios. Rental companies can bill for repairs, loss of use, towing, and admin.
Key exclusions, ideally referenced or available, so you can confirm it applies to the vehicle class you are hiring.
A printed copy is helpful, but a PDF on your phone is usually sufficient. The most important part is that the information is readable quickly, without you having to scroll through dozens of pages.
2) Credit card benefit letter or guide to benefits
If your cover comes from a credit card, bring the “guide to benefits” or a benefit letter that shows rental car coverage terms. Agents often ask whether the card provides primary or secondary coverage, and whether it covers the full value of the vehicle. You do not need to win an argument, but you do need to understand what you have.
For credit card cover to be meaningful, you typically need to pay for the rental with that card and decline the rental company’s waiver. Some benefits exclude certain vehicles, including large SUVs or premium models, and some exclude specific locations or types of use. If you are picking up in Orange County, pages like Santa Ana (SNA) and SUV hire from SNA are a reminder to check vehicle-class exclusions before you reach the counter.
3) Insurer contact details and claims instructions
Desk staff may not read a full policy, but they will respond well to confident, practical preparation. Have a page or screenshot with:
Insurer name and policy number.
24-hour claims line and email.
What to do after an incident, for example, police report requirements, photos, or timelines.
This is not “proof” in a legal sense, but it is evidence you can handle the process. It can reduce back-and-forth if the agent is probing whether you understand what declining means.
4) Proof of identity consistency, and named drivers
One common reason desk interactions get tense is not insurance at all, it is mismatched names. If your policy is in a slightly different name format than your booking, the agent may question it. Ensure your documents match across:
Passport.
Driving licence.
Rental voucher and booking confirmation.
Insurance document.
Also, if there are additional drivers, your third-party cover may only apply to the policyholder or named drivers. If the second driver is likely to drive most of the time, make sure the cover applies to them too.
5) Evidence your cover includes common rental company charges
When travellers say they have “excess cover”, they often mean it only reimburses the excess. Rental companies in California can charge additional items after damage, such as:
Loss of use, the time the car is unavailable for hire.
Diminution of value, the reduced resale value after repairs.
Towing and storage.
Administrative fees.
If your policy covers these, having that line highlighted in the policy wording is useful. If it does not, be realistic about the risk you are retaining when you decline LDW/CDW.
How to present your proof at the counter without inviting extra pressure
The fastest way to avoid counter pressure is to keep your explanation short and avoid debating policy details. A practical approach is:
State your decision once, for example, “I will decline LDW and CDW, thank you.”
If asked why, say you have your own cover and can show the certificate.
Show the schedule page with name, dates, territory, and benefit limit.
Ask for confirmation in writing that you declined the waiver, then review the contract before signing.
Remember that desk agents often work from scripts and may be measured on sales. You do not need to justify your personal risk decision beyond confirming you understand you are responsible for damage and will be charged first.
How to handle common counter statements calmly
“Your insurance will not be accepted here.” They may mean they cannot treat it as a substitute for their waiver. You can still decline, but you may face a higher deposit. Ask what the deposit will be without LDW/CDW and confirm it is available on your card.
“If anything happens, you will pay the full value.” This is often true operationally. The rental company charges you, then you seek reimbursement. Make sure your policy limit is high enough for the vehicle class you are hiring.
“Your credit card won’t cover it.” Ask which part they believe is excluded. If you have the benefit guide and it clearly applies, you can proceed. If you are uncertain, decide based on your risk comfort, not on pressure.
“Sign here, it’s just standard.” Do not sign without checking whether LDW/CDW has been added. Look for line items that include LDW, CDW, DW, or similar abbreviations, and confirm the total daily rate matches what you expect.
Practical checklist before you travel to California
Prepare these items so you are not searching in the queue:
One-page summary of your third-party cover with name, dates, territory, limit.
Full policy wording saved offline, for exclusions and claims steps.
Payment card readiness, ensure the card has enough available credit for the deposit.
Vehicle class fit, ensure your policy includes SUVs, convertibles, or premium cars if relevant.
Incident kit, know you may need photos, a police report number, and written confirmation from the rental company after any damage.
If you want to compare how suppliers present terms at different California locations, Hola Car Rentals publishes local pages such as Alamo at LAX and Enterprise in San Diego, which can help you anticipate the pickup flow and typical add-ons shown at the desk.
Important caveats: when declining is unwise or may not work smoothly
Even with perfect documents, there are situations where declining LDW/CDW may be riskier. If your cover is reimbursement-only, you must be able to tolerate a large temporary charge. If your policy excludes certain roads, off-road use, single-vehicle incidents, glass, tyres, underbody, or roof, your “proof” will not help if the claim is denied. Also, if you arrive without a major credit card or your card cannot support the deposit, the rental company may require you to take their waiver or may not release the vehicle.
Finally, be careful with language. In the UK, “excess waiver” is a familiar phrase, but US counters may use different terms. Focus on the concrete items, the waiver line item on the contract, the deposit amount, and what you are agreeing to pay if something happens.
What to check on the rental agreement before you leave the lot
After the desk, review the agreement on paper or on-screen:
Waiver status, it should show declined, rejected, or not selected for LDW/CDW.
Price breakdown, confirm no daily charge for the waiver is included.
Deposit or authorisation, confirm the amount and that it is an authorisation, not a purchase.
Driver details, confirm all named drivers are listed if they will drive.
Damage inspection, photograph all sides, wheels, glass, interior, and note existing marks.
These steps do more to protect you than any argument at the counter. Proof is helpful, but documentation of the vehicle’s condition and a clean contract are what prevent disputes later.
FAQ
Do rental companies in California have to accept my own insurance as proof to decline LDW/CDW?
Not usually. LDW/CDW is typically optional, and the rental company may still let you decline, but they are not obliged to validate or “accept” your third-party cover as a substitute for their waiver.
Is a PDF on my phone enough, or do I need printed documents?
A clear PDF is usually enough if it shows your name, dates, territory, and benefit limit. Printing can help if your phone battery dies or signal is poor, but readability is what matters most.
What if the agent says I will be charged for any damage if I decline?
That is often correct operationally. The rental company may charge you first, then you claim reimbursement from your insurer. Make sure you can cover the deposit and any temporary charges.
Does credit card cover count as proof for declining LDW/CDW?
It can, if you can show the benefit guide and you meet the conditions, such as paying with the card and declining the waiver. Check exclusions for vehicle types and any limits that may be too low.
How do I stop LDW/CDW being added “by mistake”?
Ask the agent to mark it declined, then review the itemised charges before signing. After signing, check the final agreement for any daily waiver line items and query them immediately.
