Car Rental in Portugal, Portugal: A Practical Guide

This guide covers everything you need to secure your vehicle and drive legally in 2026.

Navigating a car rental in Portugal, Portugal is straightforward if you prepare for local legal requirements. Whether you plan to explore the historic center of Portugal or take day trips across the region, having your own vehicle offers unmatched flexibility. However, driving here involves specific regulations that differ from other European destinations. Since January 2023, all rental vehicles must be equipped with an automatic toll transponder, changing how drivers handle motorway fees. Additionally, rental agencies enforce strict rules regarding security deposits, driver age, and licensing. This guide outlines the essential steps to secure a car hire in Portugal, Portugal, helping you avoid common pitfalls at the rental counter. From understanding speed limits to preparing the correct credit card, here is what you need to know before hitting the road in 2026.

L'essentiel

When arranging a car hire in Portugal, Portugal, you must meet specific legal and rental agency requirements. The legal minimum driving age in Portugal is 18 years. However, most rental agencies require drivers to be between 18 and 21 years old, with a license held for at least one year. If you are under 25, expect a young driver surcharge.

For documentation, drivers with an EU/EEA driving license do not need an International Driving Permit (IDP). Non-EU drivers typically require an IDP alongside their national license, especially if the home country's license is not written in the Roman alphabet (though requirements also depend on the issuing country and specific international agreements).

On the road, keep speed limits in mind: 50 km/h in urban areas, 90 km/h on open roads, and a maximum of 120 km/h on motorways. Note that motorways also enforce a minimum speed limit of 50 km/h. When parking, look for designated zones and pay attention to local signage to avoid fines.

Security Deposits and Booking Policies

Securing your rent a car in Portugal, Portugal requires a valid credit card. Rental agencies do not universally accept debit cards for security deposits; instead, they strictly require a credit card issued in the primary driver's name.

When you pick up the vehicle, the rental company will place a temporary hold on your card. Security deposits typically range between €300 and over €1,000, depending on the vehicle class and the provider's terms. This hold is released after you return the car undamaged.

To secure the best rates and ensure vehicle availability, it is highly recommended to book your car rental in advance. While booking, check if the agency includes basic insurance coverage and clarify their fuel policy (usually full-to-full) to avoid unexpected charges at the end of your rental period.

Where to Pick Up Your Car

If you are looking to secure a car rental in Portugal, Portugal, you will find rental offices positioned at key transit points. The most convenient locations for pickup include the local airport terminals, central train stations, and downtown rental depots.

Major international rental brands and local Portuguese providers operate desks directly inside the airport arrivals area, allowing you to collect your keys immediately after landing. If you prefer to pick up your vehicle later, downtown offices offer a convenient alternative, though they may have shorter operating hours compared to airport locations. When booking, verify the exact address of the rental desk and check if the provider offers out-of-hours pickup services if your flight or train arrives late in the evening.

Navigating Tolls and Road Trips

Portugal's toll system can be complex, featuring both traditional barrier toll booths and electronic-only (SCUT) motorways. Under Decree-Law No. 84-C/2022, effective January 8, 2023, all car rental companies in Portugal must equip their vehicles with an automatic electronic toll payment system (a Via Verde device).

This transponder automatically records your toll usage as you pass through electronic toll gantries or dedicated Via Verde lanes at traditional booths. The rental agency will bill these charges to you. Note that rental car drivers can no longer pay electronic-only tolls post-trip at CTT post offices, as this option was officially removed for rental vehicles by the 2022 decree. The exact daily administration fee for the Via Verde device and the specific toll tariffs vary depending on your route and vehicle class, so confirm these details with your provider at pickup.

Where to go by car

Tolls: motorway estimate (~€0.11/km) — free secondary routes often exist.
