Driving a car rental in Greece is certainly the most convenient way to see the country’s attactions, fabulous coastlines and landscape. Greece has a well-maintained roadway system that makes it quite easy for travelers who rent a car. The highways from Athens to Thessaloniki and from Athens to Corinth, Tripolis and Kalamata are excellent, while northern Greece is crossed by the recently-completed Egnatia Road. More highways are under construction, for example the road from Corinth to Patras.The most challenging parts of driving a car hire in Greece are the narrow roads in the countryside and in the Greek islands. These roads usually have one line per direction and they are windy due to the mountainous landscape of the country. You are adviced to drive slowly in these roads, keep the speed limits and pull over to allow oncoming traffic from local cars.Also in the highways, keep cash on hand for paying tolls. Toll rates are about 2.5-3.5 euros for a normal passenger car. Certainly it is illegal to use the cell phone while driving and you may be stopped and fined if you violate this law. As for parking your car rental, better make sure that your hotel has a parking space because on-street parking may be hard to find in large cities or during high season.
