Saturday 'Hoy No Circula' Restrictions Enforced in Mexico City and State of Mexico

Overview of Saturday Restrictions

On March 21, 2026, authorities in Mexico City and the State of Mexico implemented the scheduled 'Hoy No Circula' (Today It Doesn't Circulate) program. This environmental initiative is designed to reduce vehicular emissions and manage traffic congestion within the Valley of Mexico Metropolitan Area.

Program Scope and Compliance

The Saturday edition of the program applies specific restrictions based on the vehicle's hologram and the final digit of the license plate. Compliance is mandatory for most vehicles, with exceptions generally reserved for electric, hybrid, or vehicles with specific emissions exemptions. Key aspects of the enforcement include:

• Restrictions for vehicles with Hologram 1 and specific license plate endings.
• Total circulation bans for vehicles with Hologram 2 on designated Saturdays.
• Monitoring by traffic authorities across the 16 boroughs of Mexico City and 18 municipalities in the State of Mexico.

Environmental Context

The 'Hoy No Circula' program is managed by the Environmental Commission of the Megalopolis (CAMe). The commission monitors air quality levels continuously, and while Saturday restrictions are routine, they can be intensified if atmospheric conditions deteriorate. Officials emphasize that the program is a critical tool for maintaining public health standards in the region.

Driver Guidance

Authorities reminded motorists that failure to comply with these restrictions results in fines and the potential impoundment of the vehicle. Drivers are encouraged to consult the official 'Hoy No Circula' website or use the dedicated mobile applications to verify their vehicle's status before traveling. As one official noted, 'Adherence to these measures is essential for the collective well-being and air quality of our metropolitan area.'
