A collision damage waiver is not an insurance policy but a promise: the car rental company waives its right to charge you the full value of the vehicle, provided you pay an excess. That excess, commonly 800 to 2500 euros on a French rental, is what CDW leaves uncovered, and theft protection carries a second one.
The short version
- The collision damage waiver, or CDW, is included in almost every rate advertised in France. The excess it leaves you owing is not.
- The excess is the maximum you pay if the rental car is damaged or stolen, and it is the sum blocked on the main driver credit card.
- Super CDW sold at the counter removes that financial responsibility for a cost of 15 to 30 euros a day, and over two weeks it often exceeds the price of the car.
- Standalone car hire excess insurance bought online provides the same coverage for a fraction of the counter price, but it reimburses you afterwards.
- Tyres, glass, roof and undercarriage sit outside standard CDW at most car rental companies, and they are the parts that get damaged.
What a collision damage waiver actually is
The collision damage waiver, shortened to CDW everywhere in Europe, is a contractual waiver rather than an insurance product. Under the rental agreement you are liable for the vehicle from the moment you take the keys, and that responsibility runs to its full value. CDW limits it: the car hire company waives the balance above an agreed ceiling, and that ceiling is the excess. Nothing is insured in the legal sense, which is why the wording on your rental contract says waiver and not policy.
The distinction matters when something goes wrong. An insurer investigates a claim, applies a policy and pays a third party. A rental company simply charges the card it holds, up to the excess, and releases the rest. There is no claim to file and no insurance cover to invoke, so the argument you may have to win is about the damage itself, not about the terms of a policy.
You will also see LDW, or loss damage waiver, used interchangeably in documents written for American renters. In practice a French rental bundles CDW with theft protection, so the two abbreviations describe the same package: the car hire company drops its claim on the vehicle if it is damaged, and drops it again if the car is stolen.
The excess: the part of the damage you still pay
Every waiver keeps a floor of liability with the renter, and that floor is what the industry calls the excess, the deductible in North American wording. It is the amount the hire company is entitled to claim from you whatever happens to the car, and it is the single number that decides whether a cheap rate is genuinely cheap.
How much excess to expect in France
Excess levels track the car category rather than the length of the rental. A compact hatchback commonly carries an excess around 800 to 1200 euros, an estate or a small SUV climbs towards 1500 to 2000, and a premium model or a nine seat van reaches 2500 euros or beyond. The figure appears on the rental agreement, and the same sum is pre-authorised on the credit card of the main driver at pick-up, which is why a card with a modest limit can block a booking that was otherwise paid for.
Read the number rather than the reassurance. Rates advertised as fully inclusive still carry an excess in the large majority of cases, and a counter agent describing the car as covered is describing the waiver, not the excess underneath it.
Checking the excess before you book
The figure is published, though never prominently. On a booking page it sits in the terms and conditions of the rate, under a heading naming what is included and what is not, and two rates for the same car from the same company can carry different ceilings. The cheaper one is frequently the one with the higher excess. Be aware of that difference when comparing quotes, and write the amount down next to the daily price. Business travellers booking through a corporate tool should ask for the same detail, since a negotiated rate sometimes includes an excess reduction that makes the counter offer pointless.
Theft protection and its own excess
Theft protection, often labelled TP or THW, works on the same principle for a different risk. If the rental vehicle is stolen, the company waives the value of the car above a ceiling, and that ceiling is a separate excess with its own amount. Theft cover is normally conditional on producing the car key and a police report, and losing the key with the vehicle is the classic way to find that the protection no longer applies.
The two ceilings are not cumulative in ordinary use, since a car is either damaged or stolen, but they are quoted separately on the rental contract and they are rarely identical.
CDW and excess insurance are not the same product
These two terms get used as if they were interchangeable, and they describe opposite mechanisms. CDW is granted by the car hire company and reduces what it may claim from you. Excess insurance is bought from an insurer and reimburses what the rental company has already taken. One caps a liability, the other refunds a payment.
The practical consequence is who holds the money in the meantime. With CDW alone, a scratched bumper means the rental company charges the repair to your card, up to the excess, and the matter ends there. With a standalone hire excess insurance policy, the same charge still leaves your account: you then send the repair invoice and the rental agreement to your insurer, and the refund arrives weeks later. Anyone travelling on a tight balance should plan for that gap rather than assume the cover is instant.
What a French rental already includes
Third party liability insurance is compulsory under the French Code des assurances and comes with every vehicle rented in the country. It pays for injury and damage you cause to other people, and its limits are high. What it never does is pay for the car you are driving, and that single gap is the whole reason CDW exists.
Beyond third party liability, most rates advertised in France include the collision damage waiver and theft protection as standard, plus roadside assistance and unlimited or generous mileage. The excess is the deliberate exception. It is what allows a rental company to advertise a low daily price while keeping a real financial exposure on the renter, and it is where the counter conversation about extras begins.
Cover is also territorial. A rental authorised for France alone loses its damage waiver the moment the car leaves the country without permission, so anyone planning to drive a rental car abroad from France needs the journey recorded on the rental agreement first.
Three ways to cover the excess
Once the excess is known, the question is whether to carry it yourself or transfer it. Three options exist, and the difference in cost runs to an order of magnitude for a comparable result.
| Route | Typical cost | Who pays first | Main limit |
|---|---|---|---|
| Super CDW at the counter | 15 to 30 euros a day | Nobody, the excess is waived | Keeps the standard exclusions |
| Standalone excess insurance | A few euros a day, single trip or annual | You, then reimbursed | Paperwork and a delay |
| Credit card coverage | Included with the card | You, then reimbursed | Conditions on card and vehicle |
Super CDW bought at the desk
Super CDW, sold as excess reduction or full protection, is the optional extra the agent offers while printing the rental agreement. It cuts the excess to a token sum or to zero, takes effect immediately and involves no claim of any kind. That simplicity is what you are buying, and the price reflects it: 15 to 30 euros a day for a compact car, more for a larger vehicle. On a fourteen day rental the total frequently exceeds the price of the car itself, and it is charged whether or not the vehicle comes back untouched.
Standalone car hire excess insurance
A standalone hire excess insurance policy is bought online from a specialist insurer before departure, as a single trip or as an annual contract covering every rental in the year. It costs a fraction of the counter price for a comparable ceiling, and the annual version pays for itself over two short trips. The catch is the reimbursement model described above, plus the exclusions written into the terms and conditions: read what the insurance policy says about vans, about drivers under 25 and about rentals longer than a month before assuming it applies. Scope varies as well: a European contract costs less than a worldwide one, several insurers require you to be resident in the country of purchase, and the larger vans fall outside the definition of an eligible vehicle.
Credit card coverage
Premium cards frequently include rental car insurance as a cardholder benefit, and the cover can be substantial. American Express and the higher tiers of Visa and Mastercard are the usual examples. Three conditions apply almost universally: the rental must be paid in full with that card, the card must belong to the main driver, and certain vehicle categories are excluded. Credit card companies also expect you to decline the counter product, so buying super CDW on top can void the benefit rather than double it. Call the card issuer, ask for the terms in writing, and keep them with the rental documents.
What the damage waiver does not cover
Standard CDW carries a list of exclusions that survives most excess reduction products, and it is remarkably consistent from one car hire company to the next. Tyres and wheels, glass including the windscreen, the roof, the undercarriage, the interior, mirrors, lost keys and mis-fuelling are the recurring entries. These are not marginal risks: they are precisely what happens on narrow village streets, on gravel car parks and in underground garages with low ceilings.
Two further exclusions carry real financial weight. Damage caused while breaching the rental contract, which covers driving on unsurfaced roads, undeclared border crossings and an unregistered second driver, voids the CDW entirely. Driving under the influence belongs to the same category, and no excess reduction product, bought at the desk or online, restores anything once that is established. And loss of use, the daily amount the company charges for the time the car spends off the road, is billed on top of the repair in many rental agreements even when the excess has been reduced to zero.
The defence is dull and it works. Photograph the vehicle from every angle before leaving the airport parking, film a slow walk around it, include the roof and the wheels, and repeat the exercise on return with the return time visible. A dated set of images has settled more disputes than any insurance cover ever will.
The other extras offered at the counter
Excess reduction is not the only line the agent reads out. Two further types of insurance are commonly offered on a French rental, and neither has anything to do with the bodywork. Personal accident insurance, abbreviated to PAI, provides a lump sum in case of injury or death of the occupants, and it duplicates what most travel policies and many employer schemes already provide. Personal effects cover applies to luggage left in the car, with a low ceiling and a long list of excluded items, jewellery and laptops among them.
Neither is worthless, but both deserve a comparison with what you already hold before you say yes. A comprehensive travel policy bought for the trip normally covers the same people and the same bags, and the money saved at the desk is real. The third common extra, an additional driver, is a fee rather than a type of cover: it registers a second name on the rental agreement so that the damage waiver keeps applying when that person is at the wheel. Skipping it to save twelve euros a day is the most expensive shortcut on the list.
After an accident: how the charge and the refund work
Knowing which product applies matters less than knowing what to do in the twenty minutes after a bump. Call the rental company from the roadside rather than that evening. Complete a European accident statement with the other party if one is involved, since the constat amiable is the document every insurer in France expects to see. Photograph the scene, the plates and the damage before anything is moved, and write down the place and the time.
The charge itself is automatic. The company assesses the repair, applies it to the card it holds and sends an invoice, without asking anyone. If you bought excess reduction at the desk, that is the end of the story. If your coverage comes from a standalone provider or from a bank, the reimbursement is yours to claim: send the invoice, the rental agreement, the accident statement and the photographs to the insurer, usually through a form on the insurer site, and expect a decision within a few weeks. Missing paperwork, far more often than disputed liability, is what delays a refund.
Two details cost people money at this stage. An administration fee is billed on top of the repair by most car hire companies, and it frequently sits outside the coverage you bought, so check whether the contract names it. And the sum finally charged can differ from the first estimate, depending on what the workshop finds once the panel is off, which is why the final invoice rather than the counter estimate is the document to send.
Questions asked at the rental desk
Is CDW mandatory in France?
No, but declining it is rarely an option in practice. French rental rates come with the collision damage waiver built in, and the companies that allow you to refuse it require proof of alternative cover plus a deposit equal to the full value of the vehicle. Third party liability, by contrast, is compulsory and cannot be removed.
Does my travel insurance cover the rental excess?
Very rarely. Travel insurance covers people, not vehicles, and the few policies extending to car hire excess treat it as an optional module you have to add and pay for. Check the schedule rather than the brochure, and do not assume the annual travel policy bought for flight delays reaches the rental car.
Why is the excess blocked on my credit card?
The pre-authorisation is how the rental company secures the excess without taking the money. The amount is frozen on the card for the duration of the rental and released afterwards, typically within a few working days of the return. It reduces the credit available to you in the meantime, which matters if the same card is funding the rest of the trip.
Can I buy excess insurance after picking up the car?
Yes with most online insurers, provided nothing has happened yet. Cover usually starts the day after purchase rather than immediately, so a policy bought at the airport does not protect the drive out of the car park. Buying before departure removes the question.
What happens if the rental car is stolen?
Theft protection waives the value of the vehicle above the theft excess, so you pay that excess and nothing more, provided the conditions hold. You will need the police report and the car key. Without the key, most car rental companies treat the loss as negligence and the protection lapses, leaving the full value payable.
Does the excess apply per rental or per incident?
Per incident, in nearly every rental agreement. Two separate events during the same hire mean the excess is charged twice, which is a good reason to look closely at the ceiling rather than at the daily rate when comparing quotes.
The arithmetic is usually straightforward once the numbers are on the table: the excess, the daily price of the counter product and the cost of the same protection bought elsewhere. Renting a small car for a weekend rarely justifies more than the standard package; a fortnight in a large vehicle usually does, and that peace of mind is worth buying at the online price rather than the desk price. Our guide to car rental insurance in France sets out what each line of the quote pays for, and the main car hire pages cover collection, fuel and the rest of the practical detail.
