Vehicle Restrictions

Following the activation of Phase I on December 25 due to Christmas fireworks and bonfires, Mexico State suspended the Atmospheric Environmental Contingency on December 26, 2025, as PM2.5 levels improved to acceptable ranges. The Alert Phase persists in Valle de Toluca and Santiago Tianguistenco due to ongoing pollutants, with normal Hoy No Circula rules in effect—no double restrictions.
