Renting a car is one of the best ways to explore Portugal at your own pace. A road trip through Portugal offers stunning coastal drives, historic towns, and mountain scenery. However, understanding the rental process and local requirements will help you save both money and time while ensuring a smooth experience.
Required Documents and Age Requirements for Car Rental
To rent a car in Portugal in 2026, you’ll need to meet specific requirements and provide certain documents:
Essential Documents:
- Valid driver’s license held for at least 1 year
- International passport or national ID
- Credit card in the main driver’s name (debit cards rarely accepted)
- International Driving Permit (IDP) – only required if your license uses non-Latin alphabet (Arabic, Cyrillic, Chinese, Japanese, etc.)
Age Requirements:
- Minimum age: 21 years old (some companies accept drivers from 19)
- Maximum age: 80 years old
- Young driver surcharge: Drivers under 25 typically pay €7-8 per day extra (capped at around €77 per rental)
- Premium vehicles may require drivers to be 25+ years old
Good news for international travelers: Portugal accepts licenses from EU countries, UK, USA, Canada, and Australia without requiring an International Driving Permit. However, carrying an IDP is recommended for extra peace of mind, especially if your license is not in English or Portuguese. You can apply for your International Driving License here.

Vehicle Inspection: Pickup and Return Procedures
When Picking Up Your Rental Car:
- Inspect the vehicle thoroughly for existing damage
- Document all scratches, dents, and marks in the inspection certificate
- Take photos or videos from all angles, including mirrors, tires, wheels, and undercarriage
- Verify the fuel level and record it
- Check for required safety equipment: reflective vest, warning triangle, and spare wheel
- Confirm the Via Verde transponder is installed and functioning
In Case of an Accident:
- Immediately contact your rental company for guidance
- They will coordinate with police and insurance companies
- Document the incident with photos and exchange information with other parties
- Keep all paperwork and receipts in a safe place
When Returning Your Car:
- Show the rental agent the vehicle’s condition
- Request written confirmation that there are no claims against you
- Return the car with a full tank to avoid refueling fees
Car Rental Insurance Options in Portugal
Understanding insurance is crucial for protecting yourself from unexpected costs during your rental period.
Standard Insurance (Usually Included):
- Third-party liability insurance (mandatory in Portugal)
- Theft protection (with excess/deductible)
- Collision damage waiver (with excess/deductible)
Additional Coverage Options:
- Full coverage without excess (highly recommended) – eliminates the deductible
- Personal accident insurance
- Roadside assistance
When booking through platforms like Rentalcars, Autoeurope, or Economybookings, standard insurance is typically included. Always verify what’s covered before finalizing your booking. The deposit blocked on your credit card usually covers the excess amount, fuel deposit, and VAT. Full insurance without excess reduces the deposit amount and provides peace of mind. Some credit cards offer rental car insurance – check with your provider before purchasing additional coverage.
Understanding Portugal’s Electronic Toll System (Via Verde)
Portugal uses a unique electronic toll collection system that differs from most European countries. As of 2026, all rental cars in Portugal are required by law to be equipped with Via Verde transponders.
How Via Verde Works:
- Electronic transponder mounted on the windscreen
- Automatically records toll road usage
- No stopping required at toll booths
- Use the green “V” marked lanes
- Charges billed to your credit card automatically
Via Verde Costs:
- Rental fee: €1.50-2.00 per day
- Maximum charge: Approximately €20 per rental period
- Toll road costs: Approximately €1 per 10 km of highway
- Example: Lisbon to Algarve toll roads cost around €30
Important: Some toll roads in Portugal accept payment ONLY through Via Verde – no cash or card options available. Accidentally entering these lanes without a transponder can result in fines sent to your home address months later. The Via Verde system is mandatory for all rental vehicles, making toll road travel convenient and hassle-free.
