Understanding the Hoy No Circula Program

The program applies to vehicles registered in CDMX and Edomex, and it’s enforced through checkpoints and electronic surveillance. Vehicles that violate the restrictions face fines and potential impoundment.
The program’s effectiveness is often debated, but it remains a key component of the region’s air quality management strategy. Factors such as weather conditions and pollution levels can trigger additional restrictions, including the activation of environmental contingency plans.
Vehicles with a zero-emission verification sticker are exempt from the restrictions, as are certain emergency vehicles, public transportation, and vehicles used for specific purposes. However, the vast majority of privately owned vehicles are subject to the rules.
