10 Things to Check Before You Drive Off in a Rental Car

Most rental car problems happen before you even leave the parking lot. A dent that was already there. A scratch nobody documented. A tank that’s not full.

You’re responsible for all of it unless you can prove otherwise.

Here’s what to do before you drive off.

1. Walk Around the Car — Slowly

Don’t just glance at it. Walk around every side. Check the hood, the roof, the bumpers. Look under the car if you can. Look for scratches, dents, chips, scuffs, and any damage to the undercarriage visible from the side.

Any damage you find: photograph it. Timestamp on. Multiple angles. Close up and from a distance to show location.

This five minutes is the single most valuable thing you can do. It’s not optional.

2. Check the Existing Damage Report

The rental company should give you a damage form. Compare it to what you actually see on the car. If something is missing from the form — any scratch, any dent, however small — add it, or get a staff member to confirm it in writing before you leave.

No form provided? Insist on one. Return without one is where disputes start.

In many countries, particularly in Southern Europe and Southeast Asia, this is where rental companies make money. A chip in the windshield that was already there suddenly becomes your problem. Don’t give them the opportunity.

3. Check the Fuel Level

Full tank = return it full. Half tank = return it half. Sounds simple. It isn’t.

Write down the exact level. “Half” is vague — one person’s half is another person’s three-eighths. Take a photo of the fuel gauge with the odometer visible before you drive out of the lot. If they claim you returned it with less fuel, that photo is your defense.

Watch out for the pre-paid fuel option. It sounds convenient but usually isn’t — you pay for a full tank upfront and lose whatever you don’t use.

4. Test Everything That Moves

Windows up and down. Wipers (front and rear). Lights — headlights, fog lights, hazard lights, turn signals. Air conditioning. The horn. The trunk release. All mirrors.

If something doesn’t work, you want to know now — not at the border crossing at 11pm. Get it fixed or swapped before you leave.

5. Look for Tire Damage

Flat spots, cracks in the sidewall, uneven wear — especially on the inner edge where you can’t easily see it. Tire damage isn’t always covered by standard CDW insurance. A blowout on a rental car with bad tires can be an expensive and inconvenient lesson.

Check the spare tire too. Some rental companies provide a full spare, some only a temporary inflation kit. Good to know before you need it on a mountain road.

6. Understand Your Insurance Coverage — Before You Sign

What’s the deductible (excess)? What’s excluded? Glass, tires, and the roof are commonly excluded from standard coverage.

Many credit cards offer rental car coverage — but usually only as secondary insurance, meaning your card covers what the rental company’s insurance doesn’t. And often not for SUVs, vans, premium vehicles, or off-road use. Know exactly what your card covers before you decline the rental company’s own coverage.

Full-cover insurance with zero deductible is available from third-party providers (Allianz, Coverage Genius, others) and is often cheaper than buying it at the counter. Book it in advance.

7. Know the GPS and Data Situation

Navigation included in the car or not? Works offline or requires a SIM data connection?

Cheaper option: download Google Maps or Maps.me offline for your destination before you travel. It costs nothing, works without a signal, and is often more up-to-date than built-in car navigation. See also our guide 7 Airport Tricks That Save Time for how to prepare before arriving somewhere new.

8. Check Your Coverage for Cross-Border Driving

Planning to drive into another country? Many rental agreements explicitly prohibit this or require a written cross-border permit and an extra fee. Albania, Kosovo, Bosnia, and some Eastern European countries are frequently restricted even from neighboring countries.

Check before you go. The question at the border — “is this vehicle allowed here?” — is not one you want to be answering for the first time.

9. Know Exactly Where and When to Return It

Airport returns, city returns, after-hours returns, one-way fees. If you’re dropping the car at a different location from pickup, confirm the one-way surcharge in writing. These fees can be substantial — sometimes several hundred euros — and aren’t always visible in the base price.

For after-hours returns: get written confirmation of the procedure. Some companies inspect the vehicle when you drop it — others when they feel like it, hours or days later. A timestamped photo set at drop-off protects you.

10. Photograph Everything — At Return Too

Already said it for pickup. Worth saying again for return: before you hand over the keys, photograph every panel, the fuel gauge, the odometer, and the condition of the car. If a dispute arises after you’ve left — and this happens — your photos at both ends are the evidence.

Send them to yourself by email immediately so they’re timestamped and backed up.

Most rental car problems are predictable. Ten minutes at the lot saves you hours later — and often real money.

Frequently Asked Questions

What does credit card rental car insurance actually cover?

It depends on the card and the country. Premium cards (Amex Platinum, some Visa Signature cards) offer primary coverage — they pay first, before any personal auto insurance. Standard cards offer secondary coverage only. Most cards exclude certain vehicle types and countries. Read the card’s benefits guide carefully, or call the number on the back to ask specifically about rental car coverage in your destination.

What’s the cheapest way to rent a car in Europe?

Compare through aggregator sites (Rentalcars, DiscoverCars, AutoEurope) — they often undercut booking directly with the rental company. Book early — prices rise significantly as the date approaches. Pick up away from airports if possible (airport location surcharges are real). Consider smaller local companies for longer rentals, but check reviews carefully.

What happens if there’s damage you didn’t cause?

Document everything. If a dispute arises, you’ll need your pre-rental photos, the damage form, and any witness accounts. Contact your credit card company or third-party insurer immediately — don’t let the rental company charge your card first and argue later. If you have zero-excess insurance, the process is simpler.

Which European countries allow cross-border rental car driving?

In most of Western and Central Europe, yes — EU countries, Switzerland, Norway, and others are generally permitted. Restrictions usually apply to Albania, Kosovo, Bosnia & Herzegovina, Ukraine, Belarus, and Russia. Always confirm in writing with the rental company before booking.
