Driving in Kos: The Complete Local Guide

Kos is one of the easiest Greek islands to explore by car. It is compact, there are no toll roads, and a car gets you to the beaches, mountain villages and quiet corners that buses and taxis simply do not reach. But Greece has recently brought in some of the strictest driving laws in Europe, and Kos has its own local quirks — especially around parking — that catch visitors out every season. This guide covers exactly what you need to know before you drive in Kos.

Speed limits in Kos

• 30 km/h in towns and built-up areas.
• 50 km/h on the island's main road. This was recently reduced from 70 km/h, so many locals still drive at the old speed — do not assume the traffic around you is going the legal limit.

Overtaking is not allowed on most of the island

Solid white lines and road signs prohibit overtaking along most of the Kos main road. With the limit at 50 km/h, traffic can feel slow on some open stretches — and that tempts drivers to overtake. Don't: overtaking in these no-overtaking zones brings a hefty fine. And because you almost always have to speed up to do it, overtaking usually adds a second offence on top — a double infraction that can mean large fines and even a temporary licence suspension. The simple rule: be patient and stay in line.

Know the four signs

Parking is controlled by four round signs (red ring, blue field). The first two are the everyday ones; the last two run the local odd/even system.

• A single diagonal line means no parking — you may pause briefly to drop someone off or load, but not leave the car.
• A red cross (X) means no stopping at all — you cannot even pause there.
• A single white bar (I) means no parking during odd-numbered months; a double bar (II) means no parking during even-numbered months.

How the alternating I/II rule works

Kos has many one-way streets. On these, one side carries the I sign and the other the II sign, so the legal side swaps each month:

• Odd-numbered months (January, March, May, July, September, November): no parking on the I side → park on the II side.
• Even-numbered months (February, April, June, August, October, December): no parking on the II side → park on the I side.

So the legal side switches at the start of every month. This is the single most common reason visitors get parking tickets in Kos. Check the sign, then check the date.

Where you must never park

• Anywhere with a yellow curb line, plus bus stops, corners and junctions.
• The Port of Kos has no parking at all. Do not leave a car anywhere in the port area — an unattended car there can be fined. For Mascot port pick-ups and drop-offs, our team meets you and handles the handover, so you never need to park at the port.

• Scooters, quads and motorbikes are everywhere in summer — expect them to weave, and check your mirrors constantly, especially in Kos Town and around the beach resorts.
• The mountain road up to Zia and the Asfendiou villages is scenic but narrow and winding — take it slowly.
• Village lanes can be extremely narrow. Do not follow your GPS blindly into a one-car alley.
• Watch for pedestrians and cyclists on the flat coastal roads — the Tigaki to Marmari stretch is busy with both.
• On rural roads, expect the occasional animal or slow farm vehicle.

Some of the best beaches, especially around the south coast and the Kefalos peninsula, are reached by unpaved dirt tracks. A normal car can manage many of them carefully, but check your rental terms before taking a car off sealed roads. If you plan a lot of off-the-beaten-track exploring, choose your car group with that in mind.

Petrol stations are easy to find along the main road and around Kos Town and the larger resorts. They get sparser toward the far west around Kefalos, so fill up before a long day out. Many take cards, but carry some cash just in case, and note that smaller stations may close in the evening and on Sundays.

• 112 is the EU-wide emergency number for police, ambulance and fire — it works in English.
• In a breakdown or accident, get to safety, switch on your hazard lights, and contact us — our team helps you sort it out.

• Always take air conditioning — Kos summers are hot.
• Choose an automatic if you can — the mountain roads are far more relaxing without a clutch.
• Book early for July and August — demand peaks and the best cars go first.
• Do not rush. With 30/50 limits and no overtaking, journeys take a little longer — plan for it and enjoy the views.
