The LEZ in San Sebastián is an initiative aimed at improving air quality and promoting sustainable mobility. Below are detailed answers to frequently asked questions, with a special focus on tourists, including those with foreign-registered vehicles.

1. What is the LEZ in San Sebastián, and what area does it cover?
The LEZ is a designated area where the circulation of more polluting vehicles is restricted to enhance air quality. In Donostia / San Sebastián, the LEZ encompasses approximately 1.2 square kilometers in the city center.
2. Is it mandatory to display the environmental badge on vehicles within the Low Emission Zone?
No, displaying the environmental badge on your vehicle is not mandatory. However, it’s crucial to know your vehicle’s category according to the Spanish Directorate General of Traffic (DGT) to determine if it is permitted to access the LEZ.
3. Which vehicles are allowed to access the LEZ, and which are restricted?
Access depends on the vehicle’s registration country, type and the phase of the municipal rules. For vehicles registered in Spain, check the City Council’s current vehicle categories and access rules (in Spanish) and your DGT environmental category. If your vehicle has a foreign registration, prior authorization is required; see questions 4 and 5 below.
4. How does the LEZ affect vehicles with foreign license plates?
Every vehicle with a foreign registration must obtain authorization before entering the LEZ, including hybrid, gas-powered and electric vehicles. The City Council checks the vehicle type, fuel and first-registration date. Its current page lists these thresholds:
- Phase 1 (2025–2027): motorcycles and mopeds first registered from 1 July 2004; petrol and diesel cars and vans from 1 January 2006; petrol trucks, buses and coaches from 1 October 2001; and diesel trucks, buses and coaches from 1 October 2006.
- Phase 2 (from 2028): motorcycles and mopeds from 1 January 2007; petrol cars and vans from 1 January 2006; diesel cars and vans from 1 January 2014; petrol trucks, buses and coaches from 1 October 2009; and diesel trucks, buses and coaches from 1 October 2014.
Hybrid, gas-powered and electric vehicles still need prior authorization regardless of registration date. Check the City Council’s current foreign-vehicle rules before travelling, as the ordinance or its implementation may change.
5. How can I apply for authorization to access the LEZ with a foreign vehicle?
Apply before entering through the City Council’s foreign-registered vehicle authorization page. The procedure asks for the owner’s details, vehicle type and registration, first-registration date, fuel type and a copy of the technical data sheet. People applying under reduced-mobility or historic-vehicle provisions must provide the corresponding certificate. A separate confirmation is not normally sent if the submission meets the requirements; the City Council contacts applicants if information is missing or the vehicle does not meet them.
6. What transportation alternatives exist if my vehicle does not meet the LEZ requirements?
San Sebastián offers various sustainable mobility options:
- Public transport: Dbus operates the city bus network. Check its official website for current routes, timetables, alerts and fares.
- Walking: Many central sights are close to one another, so walking can be a practical way to continue your visit after parking outside the restricted area.
- Before setting off: Check the route and current traffic signs. Do not assume that a navigation app will account for every LEZ restriction.
7. Where can I park if my vehicle does not comply with the LEZ requirements?
Illunbe is one of the City Council’s park-and-ride facilities; its current information lists connections to the centre on Dbus routes 17 and 28. The city also lists other peripheral car parks and their public-transport connections. Check the official parking information before travelling, because operating arrangements can vary by season. A park-and-ride car park is not permission to drive into the LEZ: follow the signs and confirm your route.
8. What are the penalties for violating the LEZ regulations?
Entering the LEZ without the required authorization is a serious offence. The municipal FAQ states a €200 fine, which may increase by 30% for repeat offences (more than one infringement in a year). Check the City Council’s current LEZ FAQ for the latest official information.
9. When does the LEZ operate, and what if I need to enter in an emergency?
The access restriction applies every day, 24 hours a day. Signs before the entrances indicate the restriction, and cameras check vehicle registrations. Authorization should be arranged before entering. The City Council says applications related to an emergency may be submitted within 48 hours after access, but the reason must be justified (for example, a health emergency or an urgent repair). This is an exception for emergencies, not a general grace period.
10. How are motorcycles regulated within the Low Emission Zone (LEZ) in Donostia / San Sebastián?
Motorcycles and mopeds are included, but their registration-date thresholds are listed separately from those for cars and vans. If the vehicle has a foreign registration, it still needs prior authorization; check the phase-specific dates in question 4 and confirm the current requirements on the City Council’s foreign-vehicle page.
For the latest rules, maps and procedures, consult the official City Council information for foreign-registered vehicles.
Planning your visit with these regulations in mind will allow you to enjoy the city sustainably and without setbacks.
