Portugal for Australian Drivers — You Swap to the Right Here

Portugal is one of Europe’s easiest countries to tour by car, with a coastline made for road trips and a motorway network that actually works. For an Australian driver the licence and the rules feel familiar — it is the side of the road that demands attention.

Right-hand traffic is the real adjustment

Australia drives on the left; Portugal drives on the right. Coming from home, your reflexes are wired the wrong way for the first day or two — the moment that catches people is pulling out of a petrol station or onto a roundabout, where instinct points you into the oncoming lane. Take your first stretch on a quiet road rather than straight into Lisbon or Porto traffic, and make a habit of double-checking which lane is yours at every junction until it feels natural.

Licence and permit

Your Australian licence is valid for short tourist stays, and an International Driving Permit is recommended — it is a recognised translation that rental desks and police like to see alongside your licence and passport. Organise it before you leave Australia, since you cannot get one once you have arrived. The Driving Permit Checker confirms exactly what your trip needs.

The drink limit is one less thing to worry about

Here is a rare bit of good news: Portugal’s blood-alcohol limit is 0.05, the same as in most of Australia. There is no new threshold to memorise — the safe approach you already follow at home applies. Enforcement is routine, so keep it at zero if you are driving.

Speeds, tolls and the costs to expect

Motorways allow 120 km/h, slightly higher than the 110 you are used to, with rural roads at 90 and towns at 50. The thing that genuinely surprises Australian visitors is not speed but the electronic toll system — many motorways have no booths, and charges are read automatically from a transponder. Make sure your rental is set up for it, or you will get a bill weeks later. Speeding penalties commonly run from EUR 60 to 300; you can estimate one with the Speeding Fine Calculator, and our guide on who pays driving fines abroad explains how rental-company charges reach you back home. Petrol is around $1.88 a litre.
