Understanding the Hoy No Circula Program: A Comprehensive Guide
As we approach the weekend, it’s important to understand the Hoy No Circula program that affects vehicle movement in Mexico City. This plan is enforced by the Secretaría de Medio Ambiente (SEDEMA) and aims to reduce vehicular emissions, thereby decreasing air pollution.
The basic premise of the program is straightforward: to limit the number of vehicles on the road based on their hologram classification and license plate numbers. If your vehicle falls into one of the restricted categories, you must refrain from driving it on designated days, particularly during the Saturday restrictions.
Why the Hoy No Circula Program Is Important
The Hoy No Circula program is a crucial element of urban management in Mexico City and the surrounding municipalities. By limiting vehicle movement, it seeks to engage in air quality improvement measures. As the program dictates, fewer vehicles equal reduced pollution levels. However, non-compliance could result in significant fines, so it’s essential to understand when and how it applies.
The program is enforced in Mexico City’s 16 boroughs and certain surrounding municipalities in the State of Mexico, which include:
- Atizapán de Zaragoza
- Coacalco de Berriozábal
- Cuautitlán
- Cuautitlán Izcalli
- Chalco
- Chicoloapan
- Chimalhuacán
- Ecatepec de Morelos
- Huixquilucan
- Ixtapaluca
- La Paz
- Naucalpan de Juárez
- Nezahualcóyotl
- Nicolás Romero
- Tecámac
- Tlalnepantla de Baz
- Tultitlán
- Valle de Chalco
The Restrictions of Hoy No Circula on Saturdays
Understanding how your vehicle may be affected by the Hoy No Circula program requires careful consideration of the restrictions that apply on Saturdays. There are specific classifications that vehicles must adhere to in order to know whether they can circulate freely or if they are required to remain stationary.
On any given Saturday, the following conditions apply:
- Vehicles permitted to circulate all Saturdays
- Vehicles that must remain at home
- Vehicles that alternate restrictions weekly
The enforcement of these restrictions takes place from 5:00 AM to 10:00 PM, allowing drivers the freedom to move their vehicles without fear of penalties during the nighttime hours.
Which Vehicles Are Affected?
To determine if your vehicle is subject to the restrictions, it is critical to check the hologram type and license plate number. For this specific Saturday , June 21, 2025, only vehicles with a hologram 2 will be restricted from circulation. In contrast, those with holograms 0 and 00 can drive without restrictions due to their lower emissions.
Vehicles bearing hologram 1 must consult the calendar for specific restrictions. On the aforementioned date, only vehicles with odd-numbered plates will be prohibited from circulation, while those with even-numbered plates will have the following Saturday restricted.
It’s important to note the exceptions that permit certain vehicles to circulate freely regardless of their hologram classification:
- Electric and natural gas vehicles
- Vehicles displaying handicapped plates
- Public transport and funeral service vehicles
- School and passenger transport vehicles
- Vehicles dedicated to public safety and civil protection

Should you violate these restrictions, fines can range from 20 to 30 times the Unidad de Medida y Actualización (UMA), which equates to between 1,924.40 pesos and 2,886.60 pesos . Such penalties serve to reinforce the importance of adhering to the program’s rules for the health and well-being of all residents.
In conclusion, understanding the Hoy No Circula program is vital for residents and drivers in Mexico City. Awareness of the restrictions and regulations could not only save you from hefty fines but also contribute positively to reducing air pollution. Be sure to verify your vehicle’s status and plan accordingly for seamless movement.
