Kythera’s road system is good but drivers must be careful. Although distances are short roads often run along the edge of the cliff and have many bends, making driving difficult. Also, as the island's inhabitants are used to seeing fewer cars on the road in the wintertime, they often drive dangerously.
In Kythera as in the rest of Greece you drive on the right-hand side of the road. All distances are expressed in kilometers. Priority must be yielded to those coming from your right-hand side. The speed limit on main roads varies between 80 and 100 km/h (48 to 60 mph). In towns and populated areas the speed limit is 50 km/h (30 mph). Drivers and all passengers must fasten their seatbelts. Do not drink any alcohol when driving in Kythera. Legislation on driving under the influence is very strict.
Anyone riding a motorcycle or a bicycle must wear a helmet. Bicycles require front and back lights at night. Motorcycles must have their front light switched on at all times.
You must have your driver's license with you when driving. You cannot drive any other type of vehicle than the one you are allowed to drive in your country. You must be at least 21 to rent a car in Kythera.
