Do I Need Car Rental Insurance? What's Included and What's Not

Insurance is where car rental gets confusing and expensive. The counter staff will offer you cover that “reduces your excess to zero” for a daily fee, and in the moment it’s genuinely hard to know whether you need it. Here’s what’s actually included in a European rental, where the gaps are, and how to decide without overpaying — or driving off underprotected.

What’s already included

Every rental in Europe comes with three layers of cover built into the price:

• CDW (Collision Damage Waiver) — limits your liability for damage to the car.
• Theft Protection (TP) — limits your liability if the car is stolen.
• Third-party liability — covers damage you cause to others, and is mandatory by law.

So you’re never driving completely uninsured, whatever the counter implies. The catch is the excess.

The excess is the real issue

CDW doesn’t make damage free — it leaves you responsible for an excess (also called the deductible): the first slice of any repair bill, typically €800–2,000 depending on the car category and country.

Here’s how it bites in practice. At pickup, the company blocks a deposit on your credit card, usually around the excess amount. If the car comes back scratched, dented or with a cracked windscreen, the cost (up to the excess) is taken from that hold. Reducing or removing the excess is the entire point of every “extra” insurance you’ll be offered.

Your options to cover the excess

There are three realistic ways to deal with it:

1. Full coverage / Super CDW at the counter. The rental company drops your excess to zero for a daily fee, often €10–25/day. Convenient, sold hard, and the most expensive route.
2. A standalone excess policy. Bought separately beforehand (annual or per-trip), these usually cost a fraction of the counter’s version and reimburse the excess if you’re charged. The trade-off: you still pay the deposit hold at the counter and claim the money back later.
3. Your credit card. Many premium cards include rental excess cover. If yours does, basic CDW is often enough — just confirm the terms, what you’d need to claim, and that you pay for the rental on that card.

So, do you actually need it?

It comes down to what cover you already hold and your appetite for risk:

• If you have a credit card with verified rental excess cover, the included CDW is usually enough. Don’t pay twice.
• If you don’t, take some excess protection. A standalone policy is normally the best value; the counter’s full coverage is the convenient, pricier fallback.
• For a short, cheap rental, the maths can favour just accepting the excess risk — but remember a single scrape can cost more than the whole trip’s cover.

The one thing to avoid is paying the counter for cover you already hold through your card.

Read the exclusions (this is where people get caught)

“Full coverage” rarely means everything. Even the pricey counter option commonly excludes:

• Tyres, windscreen, undercarriage and roof — the parts most likely to get damaged.
• The interior and lost keys.
• Damage from off-road driving, wrong fuel, or breaching the contract (an unauthorised driver, a border you weren’t allowed to cross).

Always read what’s not covered before you assume you’re untouchable.

Practical tips

• Photograph the car at pickup and drop-off — bodywork, existing scratches, the fuel gauge and the odometer. Disputed damage is the single most common excess charge.
• Check your card’s terms before you travel, not under pressure at the desk.
• Keep all paperwork if you plan to claim on a standalone policy or your card.
• Decide in advance. Walking up to the counter with a plan is what stops you being upsold.

When comparing rates you can check what each booking includes and see full-coverage options before you arrive, so you decide calmly. It also pairs with the wider ways to save on your rental.

The bottom line

You don’t need to buy the counter’s insurance — basic CDW and theft cover are always included — but you do need a plan for the excess. If your credit card covers it, you’re set. If not, a standalone excess policy usually beats the counter on price. Either way, decide before you travel, photograph the car, and you’ll never be talked into cover you already have.
