Quick Summary:
- CDW limits what you pay if the rental car is damaged.
- Check the deductible amount, it sets your maximum out-of-pocket cost.
- Confirm exclusions like tyres, windscreen, roof, and underbody damage.
- Compare CDW with credit-card cover and your travel insurance terms.
When you arrange car hire in San Francisco, you will likely see CDW listed on the quote, the rental agreement, or at the counter. CDW usually stands for Collision Damage Waiver. It is not the same thing as standard vehicle insurance in the UK sense, but it often performs a similar job, it can reduce what you must pay if the rental vehicle is damaged in a collision, vandalised, or otherwise physically damaged while in your possession.
In practical terms, CDW is a waiver offered by the rental company. If damage occurs, and you have complied with the contract, the rental company agrees to waive some or all of its right to charge you for repairs. The important part is the “some or all”, because the exact coverage, exclusions, and the deductible, also called an excess, can differ by company, state, vehicle class, and the package you chose.
San Francisco driving brings a few specific risks that make it worth understanding CDW properly. Tight street parking, steep hills, tram tracks, heavy traffic around the Bay Bridge approaches, and high vehicle-repair costs in California can turn a minor scrape into a sizeable bill. CDW is meant to cap that exposure, but only when you follow the agreement’s rules.
What CDW typically covers in San Francisco car hire
Although wording varies, CDW for US rentals commonly relates to damage to the rental vehicle. That can include collision damage, damage caused by another party, and sometimes vandalism. It can also include loss-of-use charges in some packages, which are fees the rental company may add for the time the car is off the road.
Many travellers assume CDW also covers third-party injuries and property damage. Usually it does not. In the US, liability cover is separate. Your rental may include state-minimum liability, or it may be offered as an add-on called supplemental liability insurance. The key takeaway is that CDW is mainly about the rental car itself, not the other person’s vehicle or medical costs.
Another point that surprises people is that “included CDW” does not always mean “£0 if anything happens”. Often there is a deductible. For example, a policy might cap your responsibility at a set amount per incident. If the repair total is below that cap, you could still pay the whole amount.
CDW, excess, and deductibles, how the money part works
In UK English, most people think in terms of an excess. In US rental paperwork, you will often see deductible. Both describe the amount you may still owe even when CDW applies.
Here is how it usually plays out. If the car is damaged, the rental company assesses the damage, arranges repairs, and then charges you according to the agreement. With CDW, that charge may be reduced to your deductible amount, or waived entirely if you have “zero deductible” protection. Without CDW, you could be responsible for the full repair cost up to the vehicle’s value, plus potential administrative fees, towing, and loss-of-use.
Because California labour and parts can be expensive, even a dented bumper or scraped alloy can be costly. That is why it is worth focusing on the deductible figure, not just whether CDW is “included”.
Common CDW exclusions you should watch for
CDW generally works only if you comply with the rental agreement. If you breach the contract, the waiver can be voided, and you could be charged for the full loss. While each company differs, these are frequent exclusions and conditions you should check carefully:
Tyres, wheels, and underbody damage are often excluded or limited. This matters in San Francisco where kerb contact is common during parallel parking, and steep driveways can lead to scrapes.
Windscreen and glass may be excluded, partially covered, or covered only with an additional package. Stone chips can happen on freeways, particularly around construction zones.
Roof damage is frequently excluded. Low garages and height restrictions around city car parks can be an issue, especially with SUVs and vans.
Driving under the influence, reckless driving, or using the vehicle in prohibited areas can void CDW.
Unauthorised drivers are a big one. If someone not listed on the rental agreement drives, CDW might not apply at all.
Leaving the scene or failing to report an incident properly can also cause problems. In the US, prompt reporting is usually required, and a police report may be necessary for theft or significant damage.
CDW vs LDW, and why the wording matters
You may also see LDW, which stands for Loss Damage Waiver. LDW can be broader than CDW, because it may include theft of the vehicle as well as collision damage. Some rental companies use the terms interchangeably, others sell CDW for collision and a separate theft waiver.
The safest approach is to ignore the acronym and read the coverage description. Look for language about collision, theft, vandalism, and whether loss-of-use and administrative fees are included or excluded. If the paperwork mentions both CDW and theft protection separately, confirm whether you need both to reduce your exposure to an acceptable level.
Does your credit card cover CDW in San Francisco?
Some credit cards offer rental car cover, but the details matter. In many cases, card benefits cover damage to the rental car, and they may act as secondary cover, meaning the rental company’s CDW or your personal policy pays first. Some premium cards offer primary cover, but you often must meet conditions such as paying for the rental with that card, declining the rental company’s CDW, and ensuring all drivers are named.
It is also common for card cover to exclude certain vehicle types, for example large SUVs, vans, or luxury cars. If you are considering a bigger vehicle for family luggage or longer drives, cross-check the exclusions with your vehicle category. For California trips that include coastal routes or neighbouring cities, some travellers opt for an SUV for comfort. If that is relevant to you, you might compare categories on pages like SUV rental California LAX to understand typical class differences, then confirm how your card treats that class.
Finally, if you plan to rely on card cover, print the benefit letter or download the coverage certificate before you travel. If an incident occurs, the rental company may still charge your card first, and you then reclaim from the card insurer. That cash-flow impact is worth factoring in.
What to check at the counter, and what to document
San Francisco airport pickups and downtown counters can be busy, so it helps to know what you are checking for. Before you sign, confirm:
The deductible amount for CDW or LDW, and whether it is per incident.
Exclusions for glass, tyres, wheels, roof, and underbody.
Whether theft is included under the same waiver, or separate.
Who is an authorised driver, and what it costs to add a driver if needed.
Then document the vehicle condition. Take clear photos of all sides, the roof line, wheels, and windscreen, plus the dashboard showing fuel level and mileage if visible. In a dense city with frequent parking manoeuvres, a before-and-after photo set can prevent disputes about when damage occurred.
If you do have an incident, report it promptly as directed in the agreement. Keep copies of any police report, incident number, tow receipt, and correspondence. These documents can be essential if you are using third-party cover or making a reimbursement claim.
How CDW fits into the bigger car hire coverage picture
CDW is only one part of the overall protection setup for car hire in the US. In simple terms, think of three buckets:
Damage to the rental car, usually CDW or LDW.
Liability to others, usually separate from CDW.
Personal injury and belongings, sometimes covered by travel insurance, sometimes offered at the counter.
Because terms vary, it can help to compare how different US gateways package cover. While your question is about San Francisco, looking at how coverage is described on other destination pages can help you spot familiar terminology and optional add-ons. For instance, you might notice similar waiver language on car hire Houston IAH or Dollar car hire Newark EWR, even though local taxes and inclusions can differ.
If your plans include a larger vehicle, the same CDW questions apply, but exclusions can be more significant due to higher repair costs and height-related risks. It can be useful to read vehicle-category guidance, such as minivan hire Las Vegas LAS or van hire Nevada LAS, then bring that awareness back to your San Francisco rental discussion.
San Francisco-specific tips related to CDW
Street parking is the big one. Door dings, bumper scrapes, and kerb rash are common in tight spaces. If your CDW excludes wheels and tyres, consider how comfortable you are with that risk.
Steep hills affect clutch and brakes. While wear and tear is not typically a CDW issue, accidental impacts can happen if you are not used to hill starts or if the car rolls. Choose an automatic if that reduces stress.
Break-ins are a reality. CDW may not cover stolen personal belongings, and theft-related cover may have conditions. Keep valuables out of sight, and do not leave luggage in the car, even briefly.
Know where you are allowed to drive. Most rental agreements allow driving within California, but restrictions can apply for off-road routes. If you are heading to parks or scenic stops outside the city, confirm route permissions to avoid voiding the waiver.
