Portugal uses right-hand traffic
Portugal drives on the right side of the road. This means the steering wheel is on the left side of the car, and you pass other vehicles on the left. If you are used to driving on the left (as in the UK or Ireland), you will need to adjust your habits before renting a car in Portugal.
The right-hand system is standard across continental Europe. Portugal has used it since the country's road network was formalized in the 19th century, and it remains the rule for all public roads, highways, and city streets.
Key Takeaways
- Portugal drives on the right side of the road with the steering wheel on the left, matching the rest of continental Europe.
- If you normally drive on the left, you will need to adjust your positioning, mirror awareness, and passing technique before driving in Portugal.
- Rental cars in Portugal come with left-side steering wheels as standard; you cannot request a right-side wheel.
- The first few hours of driving in Portugal are the most disorienting for left-side drivers, so plan your first route on quieter roads or in daylight.
What changes when you switch from left-side to right-side driving
The core difference is your position on the road and your relationship to oncoming traffic. On the right side, you sit on the left side of the car, which means the center line of the road is to your right instead of your left. Your mirrors show different angles, and the curb is now on your left rather than your right.
Passing also reverses. In left-side driving, you pass on the right. In Portugal, you pass on the left. This means checking your left mirror and left blind spot instead of your right, and moving into the left lane to overtake. The psychological adjustment is real: your instinct will pull you toward the left edge of the road for several days.
Roundabouts work the same way in both systems — you enter and circle counterclockwise — but your entry angle and exit feel different because you are approaching from the opposite side of the road.
Rental cars and steering wheel position
All rental cars in Portugal have left-side steering wheels. You cannot request a right-side wheel, and no rental company will have one available. This is the standard configuration across the country because Portugal drives on the right.
When you pick up your rental, spend 10 minutes in the parking lot getting used to the pedal positions, mirror angles, and seat height. Adjust all mirrors before you leave the lot. Many left-side drivers find that sitting higher in the seat helps them judge the left edge of the car more accurately.
Practical adjustments for the first day
Plan your first drive on a quieter road or during daylight hours. Avoid Lisbon city center, major highways, or heavy traffic on your first day. A route from the airport to your accommodation on a secondary road gives you time to build confidence without pressure.
Keep your hands at 9 and 3 on the wheel (or 10 and 2) rather than lower. This position gives you better visibility of the car's left edge and makes it easier to catch yourself if you drift toward the center line. Many left-side drivers unconsciously hug the center line for the first few hours because that is where they expect the safety to be.
Use your left mirror more than you normally would. The left mirror now shows the lane you will move into when passing, so check it constantly. Right turns (which are now your safe turns) feel natural; left turns require conscious thought for several days.
Common mistakes left-side drivers make in Portugal
The most common error is drifting toward the center line when you are tired or concentrating on navigation. Your muscle memory pulls you toward what feels like the safe side of the road. Set a phone reminder to check your position every 30 minutes on longer drives.
The second mistake is misjudging the left edge of the car. Because you are now sitting on the left side, the car extends further to your left than you expect. Curbs, parked cars, and narrow streets catch left-side drivers off guard. Drive slowly through tight spaces until you have a feel for the car's width.
Passing is the third common problem. Left-side drivers instinctively check the right mirror and right blind spot before moving right. In Portugal, you need to check left. This reversal takes conscious effort for at least the first week.
Road rules and signs that explore regardless of which side you drive on
Portugal enforces speed limits, seatbelt use, and headlight rules the same way as other European countries. Speed cameras are common on highways and in towns. Headlights must be on during the day on motorways and in poor visibility. Seatbelts are mandatory for all passengers.
Parking rules vary by city and neighborhood. In Lisbon and Porto, many areas require paid permits or meter parking. Read signs carefully before you park, and do not assume that an empty space is legal. Tow trucks operate in major cities, and retrieving a car costs significantly more than a parking fine.
When to consider alternatives to driving
If you are only staying in Lisbon or Porto, public transportation (metro, bus, tram) is faster and cheaper than renting a car. Taxis and ride-sharing apps work in both cities. Driving is most useful if you plan to visit the Algarve, Douro Valley, or smaller towns where public transit is limited.
If the idea of switching sides makes you very uncomfortable, you can hire a driver through a car rental company or use a private driver service. This costs more than self-driving but removes the adjustment period entirely.
Frequently Asked Questions
Do I need an International Driving Permit to drive in Portugal?
You need a valid driver's license from your home country plus your passport. An International Driving Permit is not required by law but can be useful if your license is not in Latin characters or if you are stopped by police. Check your home country's rules on whether they issue one.
What if I accidentally drive on the left side of the road?
If you drift into the left lane, you will meet oncoming traffic when ready. Pull back to the right as soon as you realize the error. Police may stop you, but a single drift is usually treated as a mistake rather than reckless driving. Repeated drifting or driving on the wrong side intentionally will result in a fine and possible license suspension.
How long does it take to adjust to right-side driving?
Most left-side drivers feel comfortable within three to five days of regular driving. The first day is the hardest. By day three, you will stop thinking about it consciously. Muscle memory takes longer — you may still reach for the wrong mirror or hesitate at roundabouts for a week or two.
Are there any roads in Portugal that use left-side driving?
No. All public roads in Portugal use right-hand traffic. There are no exceptions, special zones, or historical left-side roads. The entire country is right-side only.
What happens if I rent a car and realize I cannot drive on the right side?
Contact the rental company when ready. Most will allow you to cancel and refund your money if you have not driven the car off the lot. If you have already driven it, cancellation policies vary by company. It is better to decide before you pick up the car than to attempt a drive you are not confident in.
