Mexico City is currently dealing with air quality issues, particularly with the presence of ozone and particulate matter (PM10 and PM2.5) as reported by environmental authorities. Despite these concerns, authorities have confirmed that there will not be a Doble Hoy No Circula activation for environmental contingencies for February 20, allowing for normal traffic flow in Mexico City and the State of Mexico. This decision comes after the monitoring on February 19 indicated poor air quality but did not meet the threshold for additional restrictions.

Furthermore, residents who rely on public transportation should be aware that Line 2 of the Metro will be undergoing maintenance, and alternative transport services (RTP) will provide coverage for affected stations. Additionally, drivers in the State of Mexico are faced with increased fees for driver's licenses, adding to the challenges for motorists in the region. These developments reflect ongoing issues of urban mobility and environmental management in the heavily populated area.

The implications of poor air quality and the operation of the Hoy No Circula program are significant for public health and urban planning in Mexico City. Residents are urged to be conscious of air quality readings and to modify their travel plans accordingly. As the city grapples with air pollution, the balance between daily commuting needs and environmental concerns remains a pressing issue for the authorities and the public alike.
