Hertz Collision Damage Waiver: What It Covers, What It Doesn't, and What Shapes Your Decision
When you rent a car from Hertz, one of the first things the counter agent will offer you is the Collision Damage Waiver, commonly called the CDW. It sounds like insurance, it's priced like insurance, but technically it isn't — and that distinction matters more than most renters realize.
What Is the Hertz Collision Damage Waiver?
A Collision Damage Waiver is a contractual agreement in which Hertz agrees to waive its right to charge you for damage to the rental vehicle if it's involved in a collision — up to the limits defined in the agreement. You're not buying an insurance policy. You're paying Hertz to release you from financial responsibility for physical damage to their car.
This distinction matters legally and practically. Because it's a waiver rather than insurance, it doesn't travel with you the way a personal auto policy does. It applies specifically to that rental, from that company, under the terms printed in your rental agreement.
What the CDW Typically Covers
When you accept the CDW, Hertz generally agrees not to bill you for:
- Collision damage to the rental vehicle, regardless of fault
- Theft of the vehicle (this may be listed separately as a Theft Protection add-on)
- Vandalism or weather damage in some versions of the waiver
- Loss of use charges — fees Hertz charges while a damaged vehicle is being repaired and can't be rented to someone else
That last item — loss of use — is one renters frequently overlook. Your personal auto insurance or credit card coverage may handle repair costs but still leave you exposed to loss-of-use fees, which can be substantial.
What the CDW Does Not Cover
The CDW is not a blank shield. Standard exclusions typically include:
- Damage caused by driving under the influence
- Damage from driving on unpaved roads if the rental agreement prohibits it
- Damage to tires, glass, the undercarriage, or the interior (these often require separate coverage)
- Damage that occurs when the vehicle is being used for commercial purposes or by an unauthorized driver
- Incidents involving gross negligence or intentional acts
Reading the actual rental agreement matters here. Exclusions vary by rental location and sometimes by state, and what's covered under one Hertz agreement may differ from another.
The Coverage You May Already Have 🔍
Before adding the CDW, it's worth understanding what you might already carry:
Personal auto insurance: If you have comprehensive and collision coverage on your own vehicle, your policy may extend to rental cars — but coverage limits, deductibles, and exclusions from your personal policy still apply. Whether your insurer covers loss-of-use charges varies by carrier.
Credit card benefits: Many travel-oriented credit cards offer rental car collision coverage as a cardholder benefit, provided you pay for the rental with that card and decline the rental company's CDW. This is typically secondary coverage, meaning it kicks in after your personal auto insurance pays — though some cards offer primary coverage.
International vs. domestic rentals: Credit card coverage often works differently or not at all outside the U.S. If you're renting abroad, the assumptions that apply domestically may not hold.
What the CDW Typically Costs at Hertz
CDW pricing varies by rental location, vehicle class, and market conditions. As a general reference point, CDW charges at major rental companies have historically ranged from roughly $15 to $30+ per day, with higher-end vehicles or specialty rentals often priced at the upper end or beyond. Rates also vary by state, as some state regulations affect how rental companies structure and price these add-ons.
Over a week-long rental, that can add $100–$200 or more to the total cost — which is why renters paying out of pocket often investigate whether existing coverage makes it redundant.
Key Variables That Shape Whether the CDW Makes Sense
No single answer fits every renter. The relevant factors include:
| Variable | Why It Matters |
|---|---|
| Your personal auto insurance | Whether you have comp/collision, your deductible, and how your insurer handles rentals |
| Your credit card benefits | Primary vs. secondary coverage, exclusions, vehicle type limits |
| Rental duration and vehicle value | Longer rentals and more expensive vehicles raise potential exposure |
| Rental location | State regulations and local pricing affect CDW terms and cost |
| Rental purpose | Business vs. personal use can affect both your policy and card coverage |
| International travel | Many standard coverages don't apply outside the U.S. |
How State Rules Factor In 🗺️
A handful of states have laws that limit what rental companies can charge you for damage — or require them to disclose the CDW terms more explicitly. Some states cap the total amount a rental company can recover for a damaged vehicle. These rules don't eliminate exposure, but they can change the math. State-level rules aren't uniform, and they change periodically.
The Gap This Creates
Understanding how the CDW works is only half the equation. Whether it duplicates coverage you already have — or fills a real gap in your protection — depends on the specific terms of your auto insurance policy, which credit cards you carry and their exact benefit language, the state where you're renting, and the type of vehicle you're renting.
Those pieces aren't something a general explanation can resolve. They live in your policy documents, your card's benefits guide, and the rental agreement in front of you.
