Overview
Greece operates one Low Emission Zone in Athens known as the Daktylios (Δακτύλιος, meaning "the Ring"). Established in 1982, it is one of Europe's oldest traffic restriction schemes, controlling vehicle access to central Athens based on license plate numbers and vehicle emissions.
The Daktylios restricts vehicles using an odd/even license plate system during winter months (October through March) and on days when air pollution exceeds safe thresholds. Vehicles with license plates ending in an odd number may drive on odd-numbered dates, and even-numbered plates on even-numbered dates.
In addition to the plate-based alternation, older vehicles that do not meet minimum emission standards may be permanently banned from the zone regardless of their plate number.
Regulations
The Athens Daktylios operates under a dual restriction system combining license plate alternation with emission-based rules:
- Odd/even plate rule: Vehicles with plates ending in an odd digit may enter on odd calendar dates; even-digit plates on even dates. This applies during activated periods (winter months and high-pollution days).
- Emission restrictions: Older petrol vehicles (pre-Euro 1) and older diesel vehicles (pre-Euro 3) may be banned from the ring zone entirely during activation periods.
- Activation: The scheme is activated during winter months (October–March) and on additional days declared by authorities when pollution levels are high.
Fines for violations range from €100 to €200, depending on the type of infringement and whether the vehicle is also in breach of emission requirements.
Foreign-registered vehicles are also subject to these restrictions when driving within the Daktylios zone.
Frequently asked questions
When is the Athens Daktylios active?
The Daktylios is typically activated during winter months from October through March. It can also be activated on additional days outside this period when air pollution levels exceed safe thresholds, as declared by Greek authorities.
How does the odd/even license plate system work?
Vehicles with license plates ending in an odd digit (1, 3, 5, 7, 9) may enter the Daktylios zone on odd-numbered calendar dates. Vehicles with plates ending in an even digit (0, 2, 4, 6, 8) may enter on even-numbered dates. This reduces traffic volume by roughly half each day.
Are foreign-registered vehicles affected by the Daktylios?
Yes. Foreign-registered vehicles must follow the same odd/even plate rules and emission requirements when driving within the Daktylios zone during activation periods. The last digit of your foreign plate determines your permitted days.
Are electric and hybrid vehicles exempt?
Yes. Electric vehicles (BEVs) and hybrid vehicles are fully exempt from all Daktylios restrictions, including the odd/even plate rule. They may enter the zone on any day during any activation period.
What is the fine for violating the Daktylios restrictions?
Fines range from €100 to €200 depending on the type of violation. Driving on the wrong plate day incurs a fine, and driving a vehicle that fails emission requirements may result in higher penalties.
