Mexico City breathed a collective sigh of relief on Thursday, January 2nd, 2025, as authorities lifted a temporary air quality alert. The initial alert, triggered by elevated levels of PM2.5 particulate matter,had prompted concerns about public health. However, improved air quality in the afternoon of January 1st led to the suspension of Phase I environmental contingency measures. The “Hoy no Circula” program, restricting vehicle use based on license plate numbers, returned to its standard schedule.
On Wednesday, January 1st, monitoring stations in the Iztapalapa borough, specifically Nezahualcóyotl and Santiago Acahualtepec, recorded PM2.5 levels exceeding 100 micrograms per cubic meter. This prompted the initial alert. However,by 6:00 p.m. that same day, most monitoring stations across the Mexico City metropolitan area showed acceptable to good air quality for both PM10 and PM2.5 particles.
The Environmental Commission of the Megalopolis (CAMe) attributed the improvement to “the ventilation that has been presented in the last few hours and improvement in meteorological conditions that has allowed the dispersion of pollutants,” according to an official statement. This highlights the critically important impact weather patterns can have on air quality, a factor familiar to many U.S. cities that experience similar fluctuations.

With the lifting of the emergency measures, the standard “Hoy No Circula” restrictions were reinstated. Vehicles with green verification stickers, ending in plate numbers 1 and 2, and displaying hologram 1 or 2 were prohibited from driving. This is comparable to some U.S. cities’ efforts to manage traffic congestion and improve air quality through vehicle restrictions.
Vehicles Allowed on January 2nd, 2025
- Electric and hybrid vehicles
- Vehicles with ecological license plates
- Vehicles with exempt hologram stickers
The situation in Mexico City underscores the ongoing challenges many global cities face in balancing economic activity with environmental protection. The experience offers valuable lessons for U.S. cities grappling with similar air quality issues and the need for lasting transportation solutions.
Navigating complex transportation regulations can be challenging. this guide clarifies exemptions for vehicles subject to restrictions, offering a clear understanding for drivers.
Exempt Vehicle Categories
Several types of vehicles are frequently enough exempt from certain driving restrictions, depending on local regulations. These exemptions typically aim to address essential services and individual needs.
- Vehicles with Specific Holograms: Cars displaying designated holograms, such as those indicating compliance with emissions standards, are usually exempt. Think of this as similar to the inspection stickers many states require for vehicle registration.
- Emergency and Essential Services: Vehicles used by healthcare workers (“Vehicles for the private use of workers in the health sector in all its specialties, paramedical and administrative, that have a valid credential, as well as ambulances”), school buses, and funeral processions are typically granted exemptions due to their critical roles.
- Disability Access: Vehicles transporting individuals with disabilities, possessing the necessary documentation (“Cars for people with disabilities that have the ‘Permission to exempt Hoy No Circula'”), are frequently enough exempt to ensure accessibility.
- Public Transportation: Public transportation vehicles, including buses and vans, that meet specific registration and licensing requirements (“All vehicles identified with a public passenger and tourism service registration card (vans, minibuses and buses or trucks) with a federal or local license plate, which comply with current verification provisions”), are generally exempt.
- Tourism and Special Permits: Vehicles with valid tourist permits or those granted special permission by relevant authorities (“All the motorcycles or cars they carry one Current Tourist Pass or with permission granted by the secretary of the Environment”) are often excluded from restrictions.
- Color-Coded Permits: In some areas, vehicles displaying specific colored stickers (“All cars that have the sticker pink, blue, yellow and red”) may be exempt. This system is comparable to some U.S. cities using color-coded parking permits.
It’s crucial to remember that these exemptions are illustrative and may vary based on specific local ordinances. Always check with your local department of Motor Vehicles or equivalent agency for the most up-to-date information on vehicle exemptions in your area.Understanding these regulations ensures compliance and helps maintain the smooth flow of traffic.
Such as, in many U.S. cities, vehicles with handicapped placards or license plates are exempt from parking restrictions. Similarly, emergency vehicles are always granted right-of-way.These are analogous to the exemptions described above.

Mexico City’s “Hoy No Circula” Program: What drivers Need to Know about Emergency Phase Suspensions
Mexico City’s ongoing efforts to combat air pollution often include temporary restrictions on vehicle use, known as the “Hoy No Circula” program. While these restrictions are designed to benefit public health and environmental quality, they can also lead to confusion for drivers, especially when emergency measures are triggered.Dr. Adriana Lopez, an expert in urban air quality and transportation policy at the National Autonomous University of Mexico, joins us today to shed light on the recent suspension of Phase I contingency measures and clarify the “Hoy No Circula” program’s nuances.
Understanding the Alert and its Suspension
Senior Editor: Dr. Lopez, thank you for joining us today. Can you help our readers understand the circumstances that led to the temporary air quality alert in Mexico City and its subsequent suspension?
Dr. Lopez: Certainly. On January 1st, monitoring stations in several boroughs detected critical levels of fine particulate matter, specifically PM2.5, forcing authorities to issue a Phase I environmental contingency alert. These alerts are triggered when air quality poses a serious risk to public health. Thankfully,by the evening of January 1st,favorable weather conditions helped disperse the pollutants,leading to a noticeable improvement in air quality. As a result, the alert was lifted on January 2nd, allowing the “Hoy No Circula” program to revert to its regular schedule.
the Role of “Hoy No Circula” in Managing Air Quality
Senior Editor: Can you explain the purpose of the “Hoy No Circula” program and how it helps in mitigating Mexico City’s air pollution challenges?
Dr. Lopez: The “Hoy No Circula” program, meaning “Today Dose Not Circulate,” is a key strategy for managing traffic and reducing emissions. It restricts the circulation of vehicles based on their licence plate numbers and hologram stickers on certain days. This helps control the number of vehicles on the road, which, in turn, reduces emissions and improves air quality.
Senior Editor: Many drivers in Mexico city are familiar with the standard “Hoy No Circula” restrictions. Though, there are exemptions for certain vehicle categories. Can you shed some light on these exemptions for our readers?
Dr. Lopez: Absolutely. While the program primarily targets vehicles with older emissions standards, there are exemptions for vehicles meeting specific criteria. These include:
electric and Hybrid Vehicles: These environmentally-friendly vehicles are generally exempt from “Hoy No Circula” restrictions.
Vehicles with Ecological License Plates:
Vehicles registered with ecological license plates, designated for low-emission vehicles, are also exempt.
* Vehicles with Exempt Hologram Stickers: Certain vehicles displaying designated hologram stickers, indicating compliance with stringent emissions standards, are allowed to circulate regardless of license plate number.
Senior Editor:
It seems like Mexico City continually evaluates and adjusts its strategies for managing air quality.This recent instance highlights the dynamic nature of these challenges and the importance of communicating any changes clearly to the public.
Dr. Lopez: You’ve articulated it perfectly. The ongoing dialogue between policymakers, experts, and the public is crucial for developing effective and sustainable solutions. we need continuous research, policy adaptation, and, most importantly, public understanding and cooperation to ensure cleaner air for all.
