Background on CAMe and its Role

The Comisión Ambiental de la Megalópolis (CAMe) is a crucial organization responsible for monitoring and managing air quality in the Greater Mexico City area. Comprising representatives from the environmental authorities of Mexico City and the State of Mexico, CAMe plays a vital role in ensuring cleaner air for millions of residents.

Contingency Suspension Details

On January 8, CAMe announced the suspension of Phase 1 of the environmental contingency due to ozone levels in the Zona Metropolitana del Valle de México (ZMVM) at 18:00 hours. This decision came after noticing improvements in weather conditions, including reduced atmospheric stability and increased wind speeds starting from 16:00 hours, which helped decrease ozone levels.

Impact on “Hoy No Circula” Program

The suspension of the contingency means that the “Hoy No Circula” (No Driving Today) program will operate normally on Saturday, January 9. Authorities anticipate better conditions for dispersing pollutants, ensuring a smoother traffic flow.

Vehicle Restrictions for Saturday, January 10

Since the contingency has been lifted, the “Hoy No Circula” restrictions will apply normally. Given that it’s the second Saturday of the month, the following vehicle restrictions will be in effect from 5:00 AM to 10:00 PM:

  • Hologram 1: Vehicles with license plates ending in the numbers 2, 4, 6, 8, and 0 are not allowed to drive.
  • Hologram 2: All vehicles with this hologram cannot circulate, regardless of their license plate ending.

However, electric and hybrid vehicles are exempt from these restrictions and can drive freely.
