Which Vehicles Are Off the Road This Monday

The Hoy No Circula program will prohibit a specific set of vehicles from circulating in Mexico City and the State of Mexico this Monday, July 27, 2026. The restriction applies to all cars with a yellow sticker (engomado amarillo), license plates ending in 5 or 6, and a 1 or 2 hologram. The ban runs from 5:00 a.m. to 10:00 p.m., covering all 16 boroughs of the capital and the 18 conurbated municipalities of the State of Mexico that participate in the program.

The rule is part of a fixed weekly rotation designed to cut emissions and traffic. Each weekday targets a different color and plate ending: Tuesday restricts pink stickers with plates ending in 7 and 8, Wednesday restricts red with 3 and 4, and Thursday restricts green with 1 and 2. Vehicles with a 0 or 00 hologram (usually newer or lower-emission models) are exempt, as are vehicles for people with disabilities that meet official norms.

Authorities have urged drivers to stay alert to announcements from the Megalopolis Environmental Commission (CAMe). If an environmental contingency is declared—typically due to high ozone or particulate levels—the regular weekday schedule can be overridden and additional restrictions may be imposed. That means even cars that normally can drive on Monday could be pulled off the road at short notice.

A Routine Restriction That Can Sharpen Overnight

Why the Monday Restriction Is Business as Usual — Until a Contingency Hits

This Monday’s ban is not a new policy; it is simply the routine application of a permanent program. The restrictions rotate by sticker color and plate digit, so they are predictable. However, the program’s real bite comes when the metropolitan area’s air quality worsens beyond a threshold. During a Phase 1 or Phase 2 contingency, the CAMe can extend the no-drive order to additional vehicles, sometimes doubling the number of cars kept off the road. For drivers, that means the difference between a planned no-drive day and a sudden, unplanned commuting scramble.

The logic behind the system is environmental: Mexico City’s valley geography traps pollutants, and the vehicle fleet contributes roughly half of the area’s volatile organic compounds and nitrogen oxides. The measure is therefore both a routine daily cap and a pressure valve for extreme pollution episodes. For tens of thousands of commuters, the practical consequence is a need to check not just the calendar but also the air-quality forecast before leaving home.

CAMe’s contingency alerts are issued the evening before or, in worsening conditions, early on the affected day. They are binding, and fines for non-compliance can reach several thousand pesos, with some municipalities also employing vehicle towing. The program therefore weaves a layer of regulatory uncertainty into daily mobility that residents learn to navigate through habit and quick information checks.

Commuter Checklist for Monday

  • Check your sticker, plate, and hologram. If you have a yellow sticker, plates ending in 5 or 6, and a 1 or 2 hologram, your vehicle cannot circulate during the restricted hours.
  • Plan alternative transport. For those affected, public transit, cycling, or carpooling with an exempt vehicle are the main options to avoid fines.
  • Watch for CAMe contingency announcements. Even if Monday is not your normal no-drive day, an environmental alert can change the rules. Check CAMe’s official channels in the evening or early morning.
  • Know the weekly rhythm. Tomorrow (Tuesday) the restriction shifts to pink stickers and plates ending in 7 or 8, so owners of those vehicles should prepare accordingly.
