The Hoy No Circula program operates daily in Mexico City and the State of Mexico with the aim of reducing pollution levels in the Valley of Mexico and Toluca. On February 19, 2026, specific vehicles must cease operation based on the color of their sticker and the last digit of their license plate. The initiative highlights environmental regulation aspects in urban areas and impacts daily commuting for residents.

As part of this program, vehicles are designated on specific days when they are not allowed to circulate. The restrictions take into account various factors including the vehicle type, year of manufacture, and the fuel type used. Additionally, vehicles with clean technologies or electric vehicles may be exempt from these restrictions, showcasing an effort to encourage eco-friendly transportation choices.

Public transport is also emphasized as a recommended alternative to reduce contamination and promote more sustainable transport solutions.
