1. The main A22 highway that runs across southern Portugal and connects cities such as Faro and Lagos is a toll road. Confusingly for visitors, though, there are no tollbooths. Instead, you’ll either need to pay at a Payshop or – and this is far more convenient – ask your Algarve car rental company for an electronic device that automatically pays the toll. Don’t be tempted to skip payment, as you’ll find a fine waiting for you when you return to the UK along with extra administrative charges from your car hire provider.
2. Bear in mind that the drink-driving limit in Portugal is 50mg of alcohol per 100ml of blood, which is significantly less than the UK limit of 80mg per 100ml. If in doubt, it’s probably best to abstain from the booze completely.
3. Most petrol stations will level a small charge (usually around €0.50) for customers who pay by credit card. Keep some cash handy while driving to avoid shelling out extra.
