Madrid has multiple Low Emission Zones (ZBE), including two specially protected areas. Entry and circulation within the city and on the M-30 ring road are banned for vehicles without a DGT environmental badge that are not registered in the capital. Each violation carries a fine of €200 (€100 if paid promptly). When passing through the A-42 tunnel connecting the Toledo highway to the M-30, cameras record violations in two ZBEs simultaneously, resulting in two fines totaling €400. Drivers are advised to bypass the M-30 using the M-40 or M-50, which are not part of the ZBE.
