Renting a Car Abroad — 15 Essential Tips for 2026

Renting a car abroad — the quick answer

The cheapest advertised rental is rarely the cheapest you pay — the money hides in the extras: excess-waiver insurance, the fuel policy, and young-driver or one-way fees. Photograph the car before you drive off, skip the desk’s over-priced cover for a standalone excess policy, and return it with a full tank. Fifteen ways to dodge the traps are below.

Every year, millions of travellers pay hundreds of euros more than they should for rental cars — through unnecessary insurance upsells at the counter, damage claims for pre-existing scratches, fuel policy traps, and cross-border surcharges they were not told about. This guide arms you with the 15 essential tips to rent a car abroad confidently and cost-effectively.

Tip 1: Book in Advance Through a Comparison Site

Never walk up to a rental counter at the airport without a reservation. Walk-up rates are almost always significantly higher — often 50-200% more than online advance rates.

Use comparison sites to find the best deal:

• Rentalcars.com — Largest aggregator with good cancellation policies
• AutoEurope — Strong in European markets
• DiscoverCars — Growing platform with competitive rates
• Kayak — Good for comparing across platforms

Timing: Book 3-8 weeks before your trip for the best rates. Very early bookings (3+ months) do not always yield better prices. If plans change, most comparison sites offer free cancellation up to 48 hours before pick-up.

Tip 2: Understand the Insurance Layers

Rental car insurance is the single most confusing and costly aspect of car hire. Understanding the layers is essential:

Layer 1: CDW / LDW (Collision Damage Waiver / Loss Damage Waiver)

Usually included in the basic rental price. It covers damage to the rental car BUT leaves you liable for the excess (deductible), which can be EUR 800-2,500.

Layer 2: Excess Reduction / Super CDW

Purchased from the rental company to reduce the excess to zero or a small amount (e.g., EUR 100). The cost is typically EUR 10-25 per day — adding up to more than the rental itself on longer trips.

Layer 3: Third-Party Excess Insurance

A standalone policy from a third-party provider (Insurance4CarHire, iCarhireinsurance, RentalCover) that covers the excess. Costs EUR 3-8 per day and often covers items excluded by the rental company’s policy (windscreen, tyres, roof, undercarriage). This is usually the best value option.

Layer 4: Credit Card Coverage

Many premium credit cards include rental car CDW coverage. Check with your card issuer for:

• Which countries are covered
• Whether you must decline the rental company’s CDW (some cards require this)
• What is excluded (tyres, glass, undercarriage, loss of use)
• The claims process (reimbursement, not direct coverage)

The Counter Upsell

Be prepared for a high-pressure insurance upsell at the counter. Staff may suggest your existing coverage is inadequate, or that you will be personally liable for thousands of euros. Know your coverage before you arrive and decline politely but firmly if you are already covered.

Tip 3: Inspect the Vehicle Thoroughly

This is perhaps the most important tip. Rental car damage disputes are the number one source of complaints among renters.

Before Driving Away

1. Walk around the entire vehicle slowly, examining every panel.
2. Check: doors, bumpers (front and rear), bonnet, boot, roof, wing mirrors, all wheels (including alloys for kerb damage), windscreen, and all glass.
3. Photograph everything. Take photos of all four sides, the roof, each wheel, and any existing damage close-up. Include a timestamp.
4. Take a video. Walk around the car recording a continuous video.
5. Mark all damage on the rental form. Be specific — “scratch on rear bumper, left side” not just “scratches.”
6. Check the interior: seats, dashboard, boot, and floor mats.
7. If in doubt, ask a staff member to confirm and sign off on existing damage.

When Returning

1. Repeat the photo and video process.
2. Return the car during staffed hours if possible. Damage claims are harder to dispute if the car was returned to an empty car park after hours.
3. Get a signed receipt confirming the vehicle was returned in good condition.
4. Save all photos and the rental agreement for at least 6 months.

Tip 4: Choose the Right Fuel Policy

Full-to-Full (Best Option)

You receive the car with a full tank and must return it full. The most transparent policy. If you return it less than full, you will be charged for missing fuel at a premium rate (often EUR 2-3 per litre).

Strategy: Fill up at a petrol station close to the return location before dropping off.

Pre-Purchase (Avoid If Possible)

You pay for a full tank at the start. You can return the car at any fuel level with no charge. The problem: you pay for fuel you do not use, and the price per litre is often higher than the pump price. Only choose this if you are certain you will use nearly the full tank.

Same-to-Same / Partial Fuel

The car is given with a partial tank and should be returned at the same level. Gauges are imprecise, making this policy prone to disputes. Avoid if possible.

Tip 5: Get an International Driving Permit

Even if not legally required in your destination country, many rental companies demand an IDP if your licence is not in the local language or uses non-Latin characters.

Being turned away at the counter because you lack an IDP is frustrating and wastes your time and money. An IDP costs less than GBP 6 / USD 20 and takes minutes to obtain. There is no reason not to have one.

For complete information, see our International Driving Permit guide.

Tip 6: Declare Cross-Border Travel

If you plan to drive your rental car into another country, you must declare this at the time of booking. Most companies allow travel within the EU/EEA but charge a cross-border fee (EUR 20-100 per country).

Common Restrictions

• Eastern Europe: Some companies prohibit taking vehicles into Romania, Bulgaria, Serbia, Bosnia, Albania, and other Balkan countries.
• Ferries: Taking a rental car on a ferry (e.g., to Sardinia, Corsica, Greek islands) usually requires explicit permission.
• UK-Europe: Driving between the UK and continental Europe via Eurotunnel or ferry typically requires declaration and may incur additional fees.
• One-way international drop-offs: Picking up in one country and returning in another is possible but expensive (EUR 100-500+ surcharge).

Driving to a restricted country without authorisation voids your insurance entirely. If anything happens, you are personally liable for the full value of the vehicle.

Tip 7: Beware of Additional Driver Fees

Adding a second driver typically costs EUR 5-15 per day. However:

• Some companies include one additional driver free (especially with full-price bookings).
• In some countries (e.g., Spain with certain companies, or included in some comparison site deals), additional drivers are free.
• All drivers must present their licence and IDP at the counter.
• Unlisted drivers are not insured. If an unlisted driver is involved in an accident, all insurance coverage is void.

Tip 8: Understand the Toll Situation

Before driving in toll countries, clarify how tolls are handled:

Electronic Toll Transponders

In Portugal, parts of Italy, and other countries with electronic tolling, rental cars may come equipped with a transponder. Clarify:

• Is the transponder included or charged separately?
• How are tolls billed? (Real-time billing, post-rental charge to credit card, etc.)
• Is there an administrative fee per transaction?

Manual Toll Roads

In France, Italy, Spain, and Croatia, keep cash and credit cards accessible for manual toll booths. See our European Road Trip Checklist for estimated toll costs.

Vignettes

In Switzerland, Austria, Czech Republic, and other countries requiring motorway vignettes, check if the rental car already has one. In Switzerland, the annual vignette should be included. In other countries, you may need to purchase one — see our road trip checklist for details.

Tip 9: Check Age Restrictions and Surcharges

Young Driver Surcharge

Most rental companies charge a surcharge for drivers aged 21-24 (sometimes up to 25). This can be EUR 10-30 per day. Some vehicle categories are restricted to drivers aged 25+.

Minimum Age

The minimum rental age is typically 21, but can be 18-25 depending on the country and company.

Senior Driver Surcharge

Some companies impose surcharges or restrictions for drivers over 70 or 75. This varies significantly by company and country.

Tip 10: Book the Right Transmission

In Europe, manual (stick-shift) transmission is the default. If you cannot drive manual, you must specifically book an automatic. Automatics are:

• More expensive (often 20-50% more)
• Less available, especially outside major airports
• More likely to be unavailable if your reserved vehicle is not available and you are given an alternative

Book automatic vehicles well in advance if needed.

Tip 11: Decline the GPS — Use Your Phone

Rental companies charge EUR 8-15 per day for a GPS navigation unit. Instead:

• Use your smartphone with Google Maps, Waze, or Apple Maps
• Download offline maps before your trip in case of signal issues
• Bring a phone mount for the windscreen or dashboard
• Ensure you have mobile data or an international roaming plan

The GPS rental fee for a two-week trip can exceed EUR 150 — more than the cost of a budget phone mount and mobile data plan.

Tip 12: Handle a Breakdown or Accident Properly

Breakdown

1. Pull over safely, activate hazard lights, and place warning triangles.
2. Put on high-visibility vests before exiting the vehicle (mandatory in most EU countries).
3. Call the rental company’s emergency number (found on the key tag or rental agreement).
4. Do not authorise repairs yourself — the rental company must approve any work.

Accident

1. Ensure the safety of all persons involved. Call emergency services (112 in Europe) if anyone is injured.
2. Exchange information with the other driver: name, licence, insurance details, registration number.
3. Take photos of both vehicles, the accident scene, road conditions, and any relevant signage.
4. Complete the European Accident Statement form (usually in the rental car’s glovebox).
5. Call the rental company and your insurance provider.
6. Do not admit fault at the scene.
7. File a police report — this is mandatory in some countries for any accident, and required by most rental companies.

Tip 13: Factor in One-Way Fees

Picking up a rental car in one city and dropping it off in another within the same country typically costs EUR 50-200 extra. International one-way rentals can cost EUR 200-800+.

Strategies to minimise one-way fees:

• Return to the same location if feasible.
• Check if certain routes have lower or no one-way fees (popular routes sometimes have balanced demand).
• Compare companies — one-way fees vary significantly between rental agencies.

Tip 14: Know the Local Driving Rules

Before driving in a foreign country, familiarise yourself with:

• Speed limits — they change at every border. See our European speed limits guide.
• Driving side — are you switching from right to left or vice versa? See our left-hand drive countries guide.
• Mandatory equipment — warning triangles, vests, first-aid kits. See our road trip checklist.
• Tyre requirements — winter tyre laws vary by country. See our tyre laws directory.
• Drink driving laws — BAC limits range from 0.00% to 0.08%. See our drink driving guide.
• ZTL zones — restricted city centre areas in Italy and other countries. Fines are automatic via camera.
• Parking rules — blue zones, disc parking, paid parking hours.

Use our country driving guides for comprehensive information on any country.

Tip 15: Keep Records of Everything

Throughout your rental, maintain a file of:

• Rental agreement (photograph each page)
• Pre-rental and post-rental vehicle photos and video
• All receipts (fuel, tolls, parking)
• Communication with the rental company
• Insurance policy documents and confirmation numbers
• The return receipt

Keep these records for at least 6 months after returning the vehicle. Damage claims sometimes arrive weeks or months later, and having thorough documentation is your best defence.
