On February 11, 2023, the Hoy No Circula program will be in effect in Mexico City (CDMX) and the neighboring State of Mexico (Edomex), prohibiting vehicles with red license plates ending in 3 and 4 from circulating to help reduce air pollution. The restrictions will be in place from 5:00 AM to 10:00 PM, and failing to comply can result in fines across the 16 boroughs of CDMX and the 18 municipalities in the State of Mexico. Additionally, some areas of the Metro are under construction affecting transit for daily commuters.

The Hoy No Circula initiative aims to improve air quality in the Metropolitan Valley of Mexico, which has been facing significant challenges related to pollution levels. With the inclusion of fines for non-compliance, residents are encouraged to find alternative transportation methods, particularly given that the Metro line impacts may disrupt normal commuting patterns. Public transportation services like RTP are being enhanced to accommodate those affected during this period.

Moreover, alongside the vehicle restrictions, residents of Edomex are confronted with increased costs for driver's licenses, adding to the financial burden of owning a vehicle. This combination of regulatory measures reflects ongoing efforts by local authorities to tackle environmental issues and manage urban mobility more effectively, highlighting the interconnected nature of transportation, public health, and environmental policy in this urban setting.
