Madrid Central is a low-emission zone in the city center. It is an area restricted to traffic with the aim of combating pollution and promoting sustainable mobility. Vehicles with an ECO label are allowed to access and circulate in Madrid Central, even during high pollution restrictions. This means they can freely drive through the area and park there, always complying with applicable regulations, such as the maximum allowed parking time. On the other hand, vehicles without an environmental label (the most polluting ones) are not allowed to access or circulate in Madrid Central. Vehicles with B and C environmental labels have restrictions on access and circulation within the Madrid Central area. If your car has a B or C label, you should check the specific regulations for your case.
