Roads in Portugal are in quite good condition. Your travel is the fastest when you choose the motorway. Using  the motorway is about 20€ for 300km for example from Lisbon to Porto or from Lisbon to Albufeira (motorway in the south going from the east to the west is free of charge)

Free local roads are often narrow and winding but if you want to get to smaller towns you have to use them. Unleaded petrol (gasolina sem chumbo) is about 1,4€.

Car parks in the city centres are about 1,00€ per hour on weekdays from 8a.m. to 8p.m.

Local drivers are used to pedestrians who walk in the streets paying no attention to traffic and traffic lights so sudden braking is not rare. 

Seat - belts fastening is obligatory on both front and back seats.

Maximum permissible alcohol in blood level is 0,5 promille.

Talking on the phone while driving is forbidden.

Caution! Strict regulations concerning checking the validity of obligatory insurance policies where introduced in December 2005. If you do not have a valid policy you may pay a road ticket 500€ to 2500€ and have your car confiscated until you pay all the costs connected with restoring the validity of your policy.
