What you need to rent a car in Spain
To rent a car in Spain, you must be at least 18 years old and hold a valid driver's license. Most rental companies require an International Driving Permit (IDP) alongside your home country license — this is a translation document, not a separate license. You can obtain an IDP from your local automobile association before you travel; it costs between $15 and $30 depending on your country and takes a few days to arrive by mail.
You will also need a valid passport and a credit card in your own name to find the rental. Debit cards are rarely accepted as the primary payment method. Some companies ask for a second form of ID, such as a national ID card. If you are under 25, expect to pay a young driver surcharge — typically €15 to €25 per day — and some companies may refuse to rent to you at all.
Your home country driver's license is legally valid in Spain for up to 12 months, so you do not need to exchange it. However, rental companies often treat the IDP as mandatory, so bring it even if Spanish law does not strictly require it.
Key Takeaways
- You need a valid driver's license, an International Driving Permit, a passport, and a credit card in your name to complete a rental.
- Rental prices vary widely by location, season, and company; airport rentals typically cost 20 to 40 percent more than city-center locations.
- Collision damage waivers and theft protection are optional add-ons that can double your daily cost, but your home insurance or credit card may already cover rental cars.
- Picking up and returning a car at different locations (one-way rental) adds a drop-off fee that ranges from €30 to €200 depending on distance.
- Spanish traffic rules include mandatory headlight use during the day, a 0.05 percent blood alcohol limit, and speed cameras on most highways.
Where to rent and what prices look like
Major rental chains operate at Spanish airports, train stations, and city centers. The largest are Hertz, Avis, Europcar, and Budget, plus local companies like Pepecar and Centauro. Airport locations are convenient but charge premium rates — often 30 to 40 percent higher than the same car from a downtown office. If you have time, taking a taxi or bus to a city-center branch can save €10 to €30 per day.
Daily rates for a compact car range from €25 to €60 in low season (November to March) and €50 to €120 in high season (June to September), depending on the city and rental company. Barcelona, Madrid, and Málaga tend to be more expensive than smaller cities. Booking online in advance usually costs less than walking in on the day. Weekly rates often include a discount — renting for seven days may cost only 4.5 times the daily rate rather than seven times.
One-way rentals (picking up in one city and returning in another) add a drop-off fee. This fee ranges from €30 for a short distance to €150 or more if you are returning to a different region. Some companies waive the fee if you book a week or longer, so ask when you reserve.
Insurance and damage coverage you should understand
Rental companies offer Collision Damage Waiver (CDW) and Theft Protection as separate add-ons, each costing €8 to €20 per day. CDW covers damage to the rental car if you cause an accident; Theft Protection covers loss if the car is stolen. Together, these can add €16 to €40 daily to your bill. However, your home car insurance policy or credit card may already cover rental cars abroad — check your policy documents or call your insurer before you travel.
If you decline the rental company's insurance and cause damage, you are liable for the full repair cost. The company will charge your credit card after you return the car, sometimes weeks later. Read the rental agreement carefully to understand what damage you are responsible for — some contracts exclude damage to the windshield, tires, or undercarriage even if you buy CDW.
Third-party liability insurance (covering damage you cause to other vehicles or property) is usually included in the base rental price and is required by Spanish law. Verify this on your contract before you sign.
Fuel, tolls, and other costs that add up
Most rental companies offer a full-to-full fuel option: you pick up the car with a full tank and return it full, paying only for what you use. Some offer a pre-purchase option where you pay for a full tank upfront at a fixed rate, usually higher than local gas prices. Avoid the pre-purchase option unless you know you will use nearly all of it. Gas stations are common along highways and in towns; fuel costs roughly €1.40 to €1.60 per liter depending on the station and fuel grade.
Spain's highway system uses tolls on most major routes. The toll system is electronic; rental companies typically equip cars with a transponder that charges tolls to your credit card automatically. You will see the charges on your final bill. Tolls range from €5 to €30 depending on the distance traveled. Some routes, particularly in Catalonia and around Madrid, are toll roads — there is no free alternative, so budget for this cost.
Parking in city centers can be expensive and complicated. Many towns use permit zones where you must display a ticket or pay via an app. Parking garages charge €1 to €3 per hour in most cities. Always lock the car and remove valuables, as theft from vehicles is common in tourist areas.
Spanish traffic rules and what happens if you break them
Spain requires headlights to be on during the day on highways and in poor visibility — this is a legal requirement, not optional. The speed limit is 50 km/h in towns, 90 km/h on regional roads, and 120 km/h on highways unless signs indicate otherwise. Speed cameras are widespread, especially on highways and near towns. Fines for speeding start at €100 and increase with how much you exceed the limit.
The blood alcohol limit is 0.05 percent — lower than many other countries. Police conduct random breath tests, particularly at night and on weekends. Driving under the influence carries fines starting at €600 and can result in license suspension or vehicle impoundment.
Seatbelts are mandatory for all passengers. Using a mobile phone while driving is illegal unless it is hands-free. Parking violations result in fines of €30 to €200, and the rental company may pass the fine to you weeks after you return the car. If you receive a traffic fine during your rental, the rental company will contact you with the amount owed.
How to book and what to check before you drive away
Book online through the rental company's website or through comparison sites like Rentalcars.com, Kayak, or Costco Travel (if you are a member). Booking directly with the company sometimes offers better rates or loyalty discounts. Compare the total price including insurance, tolls, and any young driver fees — do not compare base rates alone.
When you arrive to pick up the car, inspect it thoroughly before signing the rental agreement. Take photos or video of any existing damage — dents, scratches, missing trim, or interior stains. Point out damage to the staff and ask them to note it on the contract. This protects you from being charged for damage you did not cause. Check that the fuel gauge reads full, the spare tire is present, and the emergency kit is in the car.
Read the rental agreement line by line. Confirm what insurance is included, what your liability is if you cause damage, and what the fuel policy is. Ask about the toll system and how charges will appear on your bill. Keep your rental agreement, keys, and receipts until you return the car and receive your final bill.
Returning the car and avoiding surprise charges
Return the car on time and with a full fuel tank if you chose the full-to-full option. Late returns are charged at the daily rate or higher. Fill up at a gas station near the rental office — do not rely on the rental company's fuel service, which charges significantly more per liter than public stations.
Inspect the car one final time before handing over the keys. Take photos of the odometer reading and fuel gauge to document the condition. The staff will inspect the car and note any new damage on a form. If they claim damage you did not cause, dispute it when ready and ask to see photos or video evidence. Do not sign a form you disagree with.
Keep your receipt and final bill. Charges for tolls, fines, or damage may appear on your credit card days or weeks after you return the car. Review these charges against your rental agreement and dispute anything that seems incorrect.
Frequently Asked Questions
Do I need an International Driving Permit if I have a valid license from my home country?

Can I rent a car if I am under 25?
Yes, but you will pay a young driver surcharge of €15 to €25 per day, and some companies set a minimum age of 21 or 23. Book in advance and confirm the company accepts your age before you commit.
What happens if I get a speeding ticket or parking fine?
The rental company will receive the fine from Spanish authorities and charge your credit card. You are responsible for paying it. Fines range from €30 for parking violations to €600 or more for serious traffic offenses.
Is it cheaper to rent at the airport or in the city?
City-center rentals are typically 20 to 40 percent cheaper than airport locations. If you have time to take a taxi or bus to a downtown office, you can save €10 to €30 per day on the rental rate alone.
Are tolls included in the rental price?
No. Tolls are charged separately to your credit card through the rental car's electronic transponder. Budget €5 to €30 depending on which highways you use. Some routes have no toll-free alternative, so you cannot avoid this cost.
