Insurance traps, airport surcharges, cross-border restrictions — and the road trips that make it all worth it. Everything you need to rent confidently.
Compare Car Rental DealsSome destinations are built for cars. The great American road trips — Las Vegas to Los Angeles, the Pacific Coast Highway, the desert highways of the Southwest. The Algarve coast. The villages above Seville. The Amalfi coast roads above Rome. No train reaches these places at the pace they deserve.
But renting a car abroad comes with a set of pitfalls that can turn a great experience expensive: insurance upsells at the counter, airport pickup fees nobody told you about, and rental agreement clauses that void coverage in ways you didn't expect. This guide walks through all of it.
A rental car is transformative in some destinations and completely unnecessary in others. The rule of thumb: if the destination has excellent public transit and walkable attractions, skip the car (and the parking headache). If the best things are spread across a region or require getting off the main routes, a car earns its keep immediately.
The United States is the definitive car rental country. Distances are vast, public transit outside cities is minimal, and the most iconic landscapes are only reachable by road. A few routes worth planning around:
The best of southern Europe is scattered across coastlines, hilltop villages and wine regions that no train timetable connects efficiently. A car in Portugal or Andalusia unlocks the kind of trip that looks impossible on paper.
The rental counter is where most car rental trips go wrong financially. The agent will offer multiple insurance products, sometimes at high-pressure speed. Understanding what each one actually covers makes this a non-event.
CDW (Collision Damage Waiver) — reduces or eliminates your liability for damage to the rental car from a collision. Most standard rental rates include CDW with a significant excess (the amount you still pay before the waiver kicks in). You can purchase "excess reduction" or "super CDW" to bring this excess to zero.
LDW (Loss Damage Waiver) — similar to CDW but also covers theft of the vehicle. In some markets these are bundled; in others they're separate.
Third-party liability — covers damage you cause to other vehicles or property. This is legally mandatory everywhere and should always be included in the base rental rate. Confirm this before accepting a rate that seems unusually low.
PAI (Personal Accident Insurance) — covers medical costs for you and your passengers in an accident. If you have comprehensive travel health insurance or your home country's health system covers you abroad, this is generally unnecessary. It is the easiest upsell to decline.
Some premium credit cards offer CDW-equivalent coverage when you pay for the rental with the card. This is often genuine coverage — but it comes with important exclusions: many cards don't cover SUVs or luxury vehicles, some require you to decline the rental company's CDW entirely (not just the excess waiver), and coverage may not apply in certain countries. Get the specifics from your card issuer in writing before relying on it.
Airport car rental locations charge concession fees on behalf of the airport — typically 10–25% on top of the base rate. If you arrive at a major city, taking public transport to a city-centre branch and picking up there can meaningfully reduce the total cost.
The exception: arriving late at night, or at smaller airports where the city branch is an inconvenient distance away. In those cases, the airport premium is the practical choice.
For most destinations, booking 2–4 weeks in advance gets the best rates. Supply is most constrained in peak summer months (June–August) in southern Europe, and around major US public holidays. Last-minute availability exists but category selection is limited — and automatic transmission cars (if you need one) run out first.
Use a comparison platform to book, then check the rental company's own site for the same vehicle and dates. Occasionally direct booking is cheaper or offers better cancellation terms.
Full-to-Full is the best deal for you: you pick up with a full tank, you return it full. Simple, fair. Always choose this option when available.
Full-to-Empty is frequently offered as a "convenient" pre-purchase option — you pay for a full tank upfront at a slightly above-market rate and return empty. You almost never use the full tank, so you pay for fuel you don't burn. Decline unless genuinely necessary.
In Europe, the vast majority of rental cars are manual. Automatic cars exist but carry a significant premium and limited availability — particularly in smaller vehicle categories. If you can only drive automatic, filter explicitly when booking and confirm your selection before paying.
If you're driving in a new country (especially left-hand traffic countries like the UK, Ireland, Australia, Japan), the mental load is already high. Automatic removes one variable and is worth the extra cost for first-time visitors.
Many rental agreements explicitly prohibit taking the car out of the country of rental without prior written permission. Common restricted destinations include Morocco, Ukraine, Kosovo, and parts of the Caucasus depending on the operator. Crossing a restricted border can void your insurance entirely. Always confirm permitted countries with the rental company before your trip if you plan to cross borders.
EU, UK, Australian and most international licences are accepted at rental desks without an IDP. Driving is on the right. Speed limits are in mph (USA) and km/h (Canada). Right turns on red lights are generally permitted in the USA unless signed otherwise. Traffic can be heavy in major cities; outside them, distances between services can be significant — plan fuel stops on highway drives.
Japan requires an International Driving Permit (IDP) alongside your national licence — this is mandatory, not optional. Driving is on the left. Roads are excellent and well-signposted in both languages. Expressways require prepaid IC cards (in Japan) or cash for tolls. South Korea accepts most international licences but an IDP is advisable for rental desks.
EU licence holders drive freely throughout the EU. Non-EU visitors (US, UK, Australian, Canadian) are accepted at most rental desks without an IDP, but some countries technically require one — Italy and Spain are the most commonly cited. An IDP is cheap to obtain and takes 15 minutes; it's worth getting one for peace of mind.
Watch for: low-emission zones (ZFE in France, LEZ in UK, ZTL in Italy) that restrict older vehicles in city centres; motorway vignettes in Austria, Switzerland, Czech Republic and others.
Road conditions and driving culture vary significantly. UAE and South Africa have well-maintained roads with major rental presence. Self-drive in Morocco is popular but conditions differ from European norms. An IDP is recommended for most countries in both regions. Check travel advisories for your specific destinations before booking.
