Mexico City’s “Hoy No Circula Program”: Key Rules, Exceptions, and Benefits
Mexico City, one of the largest and most populous cities in the world, has long struggled with air pollution. With the constant flow of vehicles on its streets, smog and poor air quality have become part of daily life for millions of residents. To combat this issue, the city launched the “Hoy No Circula” (or “No-Drive Day”) program in 1989.

HOW DOES IT WORK?
“Hoy No Circula” Is a program that restricts the circulation of certain vehicles on designated days based on their license plate numbers. The goal is to reduce air pollution, decrease traffic congestion, and promote the use of public transportation or alternative means of getting around the city, like bicycles or walking.
The program works by restricting vehicles from circulating on specific days based on the last digit of their license plate number. This means that every car in Mexico City is subject to a rotation where certain vehicles can’t operate on particular weekdays.
The restriction schedule is as follows:
- Monday: Vehicles whose license plates end in 5 or 6
- Tuesday: Vehicles whose license plates end in 7 or 8
- Wednesday: Vehicles whose license plates end in 3 or 4
- Thursday: Vehicles whose license plates end in 1 or 2
- Friday: Vehicles whose license plates end in 9 or 0.
Additionally, some exceptions apply, such as for electric cars, hybrids, or vehicles that meet specific environmental standards. These vehicles are often exempt from the restrictions, as they have a lower environmental impact.
ENVIRONMENTAL AND HEALTH BENEFITS
The primary benefit of the Hoy No Circula program is its positive effect on air quality. With fewer cars on the streets, pollution levels tend to drop, leading to cleaner air for the 21 million people living in Mexico City and the surrounding areas. This is especially important since the city often experiences smog, which is caused by a mix of vehicle emissions, industrial activity, and high temperatures. Prolonged exposure to air pollution has been linked to a variety of respiratory diseases, heart problems, and other serious health conditions.
By reducing the number of vehicles on the road, the Hoy No Circula program has contributed to a noticeable improvement in air quality over the years. According to reports, the program has helped reduce vehicle emissions, lower the number of respiratory-related hospital admissions, and improve overall public health.
PUBLIC TRANSPORTATION AS A KEY ALTERNATIVE
While the Hoy No Circula program is crucial in reducing pollution, it’s not without its challenges. With millions of people depending on their cars to commute, there has been concern over the program’s impact on people’s daily lives. In response, the Mexican government has emphasized the importance of public transportation as an alternative.
Mexico City boasts an extensive and affordable public transportation network, including buses, the metro system, and a bike-share program. During Hoy No Circula restrictions, many residents turn to these modes of transport to avoid the inconvenience of not being able to drive. The city has also encouraged the use of carpooling and ride-sharing services as part of its effort to reduce individual car use.
