Many roads are three lanes wide: the middle lane is used for passing in both directions. If there is little room to pass on the road, fast drivers expect slow drivers to pull onto the shoulder in order to let them by.

Multitone horns are illegal. Use of a vehicle's horn in towns is allowed only in cases of immediate and extreme danger.

Passing is illegal when approaching a train crossing that isn't equipped with a barrier.

Fines should be paid to the public treasury, not to a police officer.

Greek-registered vehicles owned by persons who do not reside within the centre zone of Athens (the designated area or daktilio) cannot enter that zone, but this restriction does not apply to vehicles rented or those bearing foreign plates and, in either case, belonging to a person staying for less than forty days. Persons who reside in the centre (daktilio) of Athens and own a vehicle with Greek plates can drive that vehicle in that area only on even or odd dates - depending on whether their plate number is even or odd, respectively - or outside the hours between 8am and 8pm. These centre-zone restrictions are lifted during August.

Parking
You are not supposed to park within 3 metres of a fire hydrant, within 5 metres of an intersection, or within 15 metres of a public transportation stop, though practically no one follows this rule. If you park in a No Parking zone in Athens or certain other areas, the police may remove your licence plates if you owe a traffic fine or fines.
