Think renting a car in Portugal is straightforward? Think again, especially if you’re planning a family road trip with kids in tow.
Between sky-high deposits, hidden fees, car seat rules, and toll systems that confuse even locals, it’s easy to blow your budget or your patience.
We’ve lived in Portugal for over a year and a half without owning a car, but we’ve rented plenty for family weekend getaways and road trips across the country.
Along the way, we’ve discovered how to fill up the gas tank with the correct fuel type, how Portugal’s toll roads really work, and whether you’re better off driving manual or automatic here.
In this guide, we’ll break it all down: the best times to rent, how to book a car in Portugal, what paperwork you’ll need, and how to dodge the costly mistakes that catch many tourists (and families) off guard.
Should You Rent a Car in Portugal?
Renting a car in Portugal can make your road trip easier, but it depends on where you’re going and how you like to travel.
After living in Porto for a while, we started feeling antsy to get out and explore more of northern Portugal. So we rented a car and took weekend trips to nearby places in northern Portugal, such as Viana do Castelo and Guimarães. Both were doable by train, but having a car made the trip way more flexible, especially with kids and a packed cooler in the trunk.
Here’s when it makes sense to rent a car:
- You’re exploring the Algarve, especially smaller beach towns or inland villages
- You want to visit rural areas like the Alentejo or Douro Valley, or islands such as Madeira and Azores, where public transport is limited
- You’re planning a road trip and want the flexibility to stop along the way
And here’s when it doesn’t:
- You’re staying mostly in Lisbon or Porto—traffic is stressful, parking is a pain, and public transit is fast and cheap
- You’re visiting places like Sintra, Coimbra, or Braga, which are easy to reach by train or bus
What About Families?
With kids, a rental car can be a lifesaver, especially if you’re bringing strollers or want to skip long train rides with transfers. That said, lugging a car seat around (or paying rental fees for one) can be annoying. And in cities, the car often just sits in a garage while you walk or take transit.
Bottom line: Opt for car rental if you’re heading outside the big cities. Otherwise, skip it.
What You Need to Rent a Car in Portugal
Renting a car in Portugal is pretty straightforward, but there are a few rules to know before you show up at the counter.
Driver’s License and IDP
If you’re from the U.S., Canada, the UK, or most EU countries, your regular driver’s license is enough—no international driving permit needed. Just make sure your driver’s license is:
- In Roman characters (not just Cyrillic or other alphabets)
- Valid for the entire rental period
We’ve always used our U.S. driver’s license and never had an issue; no one ever asked for an international driving permit. Still, it’s a good idea to double-check the rental company’s terms when you book, just in case.
Minimum Age to Rent
Most rental companies require drivers to be at least 21 years old. Some bump that up to 23 or 25, especially for larger vehicles. If you’re under 25, expect a young driver surcharge.
Credit Card Requirements
You’ll need a credit card in the main driver’s name. Debit cards usually don’t work for the security deposit unless you’re renting through a company that explicitly allows them. The card must have enough available credit to cover the security deposit, which can range from €800 to €2,000.
Other Documents to Bring
Have these ready when you pick up your car:
- Your passport or national ID
- Your driver’s license
- The credit card you used to book (or one in the driver’s name)
- Your rental confirmation with any included coverage
Skip any of these, and you might not get the keys.
Booking Your Rental Car in Portugal
If you want the best deal and the best car for your car rental in Portugal, book early. Prices can jump fast, especially during summer and school holidays. But if you’re traveling in the off-season, you might still score a good deal at the last minute.
When to Book
In the off-season, we’ve had good luck booking car rental last-minute from the Porto Airport. Prices were reasonable, and availability wasn’t an issue. But note that my husband and I can drive manual cars.
But during busy times, like summer or Easter break, it’s a different story. Options go fast, especially for automatics or larger vehicles.
To be safe, book at least a few weeks in advance for peak travel periods.
Where to Book
Start with comparison sites like Discover Cars, Auto Europe, or Kayak to find deals across different companies. Then check if it’s cheaper to book directly with the rental company. Some offer free cancellation or include extras like a free second driver.
One-Way Rentals and Drop-Off Fees
When we first moved to Portugal, we rented a car in Lisbon to help transport some of our things north while our big items came separately by van. Dropping the car off at Porto airport worked great, but it did cost more.
One-way rentals are convenient, but they usually come with a drop-off fee (often €50 to €150), depending on the distance and company.
Airport vs. City Center Pickups
- Airport pickups are easy if you’re flying in or starting a road trip. That’s what we usually do when we need a rental, especially from Porto Airport, Lisbon Airport, or Faro Airport.
- City center pickups might be cheaper, but locations can be harder to get to, and hours are more limited.
Pro tip: If you’re spending a few days in Lisbon or Porto first, wait to rent until you’re ready to leave the city. It saves money and stress since you won’t be driving or parking in busy urban areas.
Automatic vs. Manual
Most rental cars in Portugal have manual transmission, and if you don’t specifically book an automatic transmission, you’ll probably end up with a stick shift. Automatic transmissions exist, but they’re limited and more expensive.
What’s Common in Portugal
Manual transmission cars are the norm. They’re cheaper, easier to find, and locals drive them without a second thought. Automatic transmission cars can cost €10 to €30 more per day and tend to book up fast, especially during peak season.
Our Experience
Thankfully, both my husband and I know how to drive manual, so we’ve always gone that route. It’s usually fine, until I hit one of those killer Porto hills and instantly regret everything 🤣. If you’re not confident driving a stick, don’t try to wing it. It’s not worth the stress.
Tips if You Only Drive Automatic
- Book early, especially in summer. Automatics go fast.
- Use filters on booking sites to show only automatic options.
- Always double-check your confirmation to make sure it lists the transmission type.
- Don’t count on switching to an automatic at the counter; chances are, they won’t have one.
If you’re not used to shifting gears, it’s worth paying extra for the comfort (and hill-free driving).
Choosing the Right Rental Car
The car you choose matters, especially in Portugal. Narrow roads, tight parking spots, and winding countryside drives all play a role. And if you’re traveling with kids, you’ll need to factor in extra space for gear.
Size Matters
Portuguese towns weren’t built with SUVs in mind. Many old streets are narrow, and parking garages are tight. Economy cars are easier to manage, especially in places like Guimarães, Óbidos, or Algarve where alleyways double as roads.
Our Experience
With two kids, we’re always trying to balance size and space. We need something small enough to fit through tight streets, but also big enough for two child safety seats and luggage. We usually end up with a mid-sized sedan, and they’ve worked out great. Just enough trunk space without the stress of navigating a boat through medieval alleys.
Driving in the Mountains or Countryside
If you’re heading to places like Douro Valley or Serra da Estrela, a car with a bit more power helps. A small engine can struggle on steep or twisty roads. Compact SUVs or mid-size models give you a smoother ride without being too bulky.
Bottom line: Go as small as you can without sacrificing what your family actually needs.
Understanding the Costs
The base rate might look cheap when you’re booking a car rental, but that’s rarely what you actually pay. Car rentals in Portugal come with a lot of extras, and the total can creep up fast if you’re not careful.
Base Rate vs. Final Price
We’ve definitely been duped by the base cost before. A car rental listed at €15 a day ended up doubling after insurance, toll devices, and fees. That being said, when we’ve rented during the off-season, we’ve found prices to be pretty reasonable, especially compared to other parts of Europe.
Always click through to the final price before booking and check what’s included, and what isn’t.
Excess Waiver Insurance
Your rental will include basic coverage, but the deductible (or excess) can be steep (sometimes €1,000 or more). You can:
- Pay extra for collision damage waiver coverage through the rental company
- Use a credit card that offers rental insurance
- Buy third-party insurance (cheaper but requires paying upfront and filing claims later)
Fuel Policy
Most rentals are full to full for the fuel policy; you pick it up full, and you return it full. It’s the best deal. Some companies push prepaid fuel, but unless you’re returning the car on fumes, it usually costs more.
Toll Charges
Portugal has electronic tolls on toll roads that don’t take cash or cards, just license plate scans or Via Verde transponder boxes.
- If your rental has a Via Verde transponder, you’ll be billed for tolls automatically, plus a small daily fee.
- If not, tolls will be charged later, often with a service fee.
Ask how tolls are handled before you leave the lot.
Extra Costs to Watch For
- GPS/satnav: €5–€10/day. Use your phone instead.
- Extra driver: Usually €5–€10/day.
- Young driver surcharge: If you’re under 25, expect €15–€25/day.
- Child safety seats: €5–€15/day. Bringing your own might be cheaper.
- Cross-border fee: Driving to Spain? Some companies charge €20–€60 extra.
Cancellation Policies
Cheap rates often come with strict cancellation rules. If your plans might change, pay a bit more for a flexible booking.
Tip: Read the fine print and total everything before booking. That way, you’re not surprised, and you’ll know if the deal is really worth it.
Getting Gas for Your Rental Car
Fuel policy might sound simple, but in Portugal, there are a few quirks to know (especially if you don’t want to end up putting the wrong stuff in the tank or overpaying).
Fuel Types
Most cars run on either:
- Gasoline (Gasolina)—usually marked as 95 or 98 octane
- Diesel (Gasóleo)
Always check the sticker on the gas cap or your rental agreement so you know what to use. Putting diesel into a gas car, or vice versa, can cause major (and expensive) problems.
Prepaying vs. Filling Up Yourself
Some rental companies offer prepaid fuel, where you pay for a full tank upfront and return the car empty. We never go for this. Unless you’re sure you’ll bring it back running on fumes, it usually costs more than just filling up yourself.
The better option:
- Choose Full to full (pick up the car full, return it full)
- Save your receipt from the gas station as proof in case they question the level later
Gas Stations in Portugal
- Many stations are self-service, but some still have attendants
- Prices vary a lot, especially near highways or touristy areas
- You usually pay after you fill up, either inside or at the card machine by the pump
If you’re driving long distances, don’t wait until the tank is almost empty; rural areas can have fewer stations than you’d expect.
Tip: Gas stations near airports often charge more. Fill up a few kilometers away to save a few euros.
Insurance in Portugal
Rental car insurance can feel overwhelming with all the acronyms and upsells. But once you know what’s required and what you can skip, it’s easier to make the right call without blowing your budget.
What’s Required by Law
Every rental car in Portugal includes basic liability insurance. This covers damage or injury to others but not the rental car itself.
Common Types of Insurance
Here’s what you’ll usually see at checkout:
- Collision damage waiver (CDW): Limits what you pay if the car is damaged. Still comes with a high deductible.
- SCDW (Super CDW): Reduces or removes that deductible. It’s the pricey “full coverage” option.
- Theft Protection: Covers the car if it’s stolen, but not your stuff inside.
- PAI (Personal Accident Insurance): Covers medical costs for you and passengers. Not needed if you already have travel insurance.
Third-Party and Credit Card Coverage
Many travelers use third-party insurance or their credit card benefits instead. Here’s how that works:
- Buy standalone insurance ahead of time (like through DiscoverCars or RentalCover) for much less
- Use a credit card that includes rental coverage; check the details before you travel
Important: If you use your own insurance, the rental company may still charge your credit card for damage. You’ll need to pay first, then file a claim.
Our Experience
Thankfully, our credit cards offer strong rental car insurance, so we’ve never paid extra at the counter or had a large security deposit held for the car rental. We always politely decline the upsell and have never had an issue with the rental reps, even when we picked up from airports.
Just be sure to:
- Check your credit card’s terms (you often need to pay with the same card and decline the rental company’s coverage)
- Confirm that it covers Portugal and includes collision and theft
Before you decide, compare the total cost, your risk comfort, and how much time you’re willing to spend dealing with claims.
Driving in Portugal: What to Know
Embarking on a road trip in Portugal is manageable, but there are a few local habits and rules to get used to. The roads are generally in good shape, but the driving style can feel fast, especially if you’re new to European roads.
Road Signs and Language
Most signs are in Portuguese, but they follow international symbols. Key words to know:
- Saída = Exit
- Portagem = Toll
- Atenção = Caution
Even if you don’t speak Portuguese, the signs are easy to follow once you’ve seen a few.
Speed Limits and Cameras
Portugal’s speed limits are:
- 50 km/h in towns
- 90 km/h on rural roads
- 120 km/h on highways
Speed cameras are common and fines can be mailed to you, even after you’ve returned home.
The left lane of a highway is strictly for passing, not cruising. If you hang out there too long, expect a tailgater flashing their lights.
Tolls and Payment
Portugal’s toll roads include some with ticket booths, but many use electronic tolls only. If your rental has a Via Verde transponder, tolls get charged automatically to your bill with a small daily fee. If it doesn’t, you may get billed later with an added service charge.
Ask your rental company how tolls are handled before you hit the road.
Roundabouts, Parking, and City Driving
- Roundabouts are everywhere, and yes, they can be stressful at first. They used to give me anxiety too, but knowing the rules helps: cars already inside the roundabout have the right of way, and using your turn signal makes it easier for everyone.
- Parking can be tough in historic centers. Blue lines mean paid parking. White lines are free (if you can find them). Parking garages are tight but often your best bet.
- In cities, pedestrians always have the right of way, and they take it. Be ready to stop, especially at crosswalks without traffic lights.
Drinking and Driving Laws
Portugal’s legal limit is 0.05% BAC, lower than in the U.S. For newer drivers (under 3 years experience), it drops to 0.02%. Best advice? If you’re driving, skip the wine.
Take it slow, plan your route, and don’t let aggressive drivers rush you. With a little patience, you’ll settle in quickly.
Tips for a Smooth Rental Experience
A few simple steps can save you a lot of hassle and money when renting a car in Portugal. Here’s what to do before you even pull out of the lot.
Inspect the Car Before You Leave
Walk around the car and look for dents, scratches, or curb rash. Check the mirrors, bumpers, and hubcaps. If you see anything, make sure it’s marked on the rental form before you drive off. This is especially crucial for your car rental at busy pickup locations like Lisbon Airport.
Take Photos of Everything
Snap photos of:
- Any visible damage
- The fuel gauge
- The mileage
- The full exterior of the car
Do it before you start the engine. These pictures can save you if you get blamed for damage you didn’t cause.
Know Who to Call
If something goes wrong:
- Emergency number in Portugal: 112 (for police, fire, or ambulance)
- For roadside assistance, check your rental contract; many include a direct number
- If there’s an accident, call the police, even for minor damage. You may need a police report to file an insurance claim
Keep a printed or saved copy of your rental agreement in the glovebox. And if you’re using third-party insurance, know what info you need to submit a claim later.
A little prep upfront makes the whole experience smoother and helps you focus on the fun parts of your trip.
FAQs about Renting a Car in Portugal
Do I need an international driver’s license?
Probably not. If your license is from the U.S., Canada, the UK, or an EU country—and it’s in Roman letters—you’re good to go. Some rental companies might ask for an international driving permit, but it’s rare. If your license is in another alphabet, you’ll need one.
Is it safe to drive in Portugal?
Yes. Roads are well-maintained, and drivers generally follow the rules. The biggest issues tend to be fast drivers on highways or tight streets in historic towns. Use common sense, and you’ll be fine.
Is it hard to find parking?
It can be, especially in old towns and cities like Porto, Lisbon, or the Algarve. Look for underground garages or paid street parking zones. Avoid parking in unauthorized areas—fines are real, and cars do get towed.
Can I rent a car with kids?
Yes, but you’ll need the right gear. Kids under 12 must use a child safety seat or booster. You can rent one from your car rental company (for a fee), but the quality varies. If you’re picky or want to save money, bring your own.
What’s the cheapest way to rent a car in Portugal?
–Book early, especially for automatic transmission cars (rarer and pricier than manual transmission)
-Use comparison sites to check deals
-Pick up in the city, not the airport, if prices are lower
-Avoid add-ons like GPS or prepaid fuel
-Use a credit card with rental insurance to skip high coverage fees
Ready to Hit the Road?
Car rental in Portugal gives you the freedom to explore beyond the usual tourist spots, but only if you know what to expect. From understanding insurance options to avoiding surprise fees, a little prep goes a long way.
Whether you’re cruising through the Algarve or road-tripping up to the Douro, now you’re set up for a smoother experience.
