What is Collision Damage Waiver (CDW) for Car Rentals?

A Collision Damage Waiver (CDW) in the United States is not insurance but a waiver offered by rental companies that limits or removes your financial responsibility for repair and replacement costs if a rental car is damaged, stolen, or totaled. Depending on the rental company and location, it may also cover loss-of-use fees and administrative charges. It may cost you around USD 30 to USD 40+ extra per day.

However, it is slightly different from the Loss Damage Waiver (LDW). While the terms are sometimes used interchangeably, CDW typically covers collision-related damage, whereas LDW may include theft and additional losses. Therefore, before you consider it, you must know the meaning, coverage, cost, key exclusions (such as reckless driving or unauthorized drivers), and other relevant aspects.

What is Collision Damage Waiver?

A Collision Damage Waiver (CDW), sometimes referred to as a physical damage waiver, is offered by rental companies to reduce or eliminate your financial responsibility if the rental vehicle is damaged or stolen. Here are some notable points:

  • CDW is not an insurance policy but a contractual waiver between you and the rental company.

  • It is an optional add-on that helps limit out-of-pocket costs resulting from damage, theft, or loss of the rental vehicle.

  • Liability coverage is not included.

  • Certain items, such as lost keys, tires, windshields, or accessories, may not be covered, and restrictions often apply to cross-border travel (e.g., driving into Mexico), depending on the rental company’s terms.

How Does Collision Damage Waiver Work?

A collision damage waiver is like a contract between you and the car rental company. To know how it works, look at the following points:

collision damage waiver explained

  • You will need to pay a daily fee for CDW.

  • The cost depends on the type of car rental, location, and more.

  • This means the CDW cost for rental cars in different locations (such as Dallas) varies.

  • Once you have it, you will generally not be responsible for most damage or theft of the rental car, subject to the terms and conditions.

  • However, it covers the cost of accidental damage to the vehicle.

  • Additionally, it may cover “loss of use” and towing fees, depending on the rental company.

  • You may get partial CDW with some rental car agencies.

  • However, the benefits are not always the same as full CDW and may offer limited coverage.

Tip: You can consider alternate options, such as personal auto policy, credit card coverage, and third-party insurance for rental cars for extended benefits.

What is Covered and What is Excluded?

Collision damage waiver is similar to the comprehensive coverage that you get with your existing rental insurance. Keep in mind that it does not cover everything. So, knowing what the damage waiver covers and what is excluded will help you make a wise choice:

What is covered?

  • Accidents involving rental cars with another vehicle, irrespective of who was at fault.

  • The rented car being stolen.

  • The rental car hitting stationary objects, such as mailboxes or fence posts.

  • Damage due to natural disasters or weather-related events, like flooding or hail.

  • The rented car caught fire.

What is not covered?

  • Damages and accidents caused by driving under the influence of alcohol or similar substances.

  • Costs of damages due to reckless driving.

  • Damage to the rental car while violating the rental contract, i.e., giving the car to a person with a learner’s permit or an underage driver.

  • Any damage that results from breaking traffic rules or laws.

Should You Buy CDW Coverage?

Getting a collision damage waiver is completely optional in the USA. However, you must compare the following scenarios to decide when you can decline the CDW and when you should get it.

When to decline?

  • If you have a personal auto policy that covers rental cars, you can decline CDW.

  • However, it is advised to contact your insurance provider to know the deductibles and coverage limits.

  • Some credit cards also offer secondary coverage.

  • While using a credit card for security deposits, be sure to check this coverage as well.

When to purchase?

  • If you do not have an auto insurance policy, CDW is recommended.

  • You can use it to fill gaps if the existing policy has limited coverage and higher deductibles.

  • To keep your personal auto policy safe, you can opt for CDW for collision coverage.
