Overview
- The fourth‑Saturday pattern ran on January 24 from 5:00 to 22:00 across the ZMVM, ZMVT and ZMST metropolitan areas.
- Vehicles with Holograma 1 and even plate endings (0, 2, 4, 6, 8), all Holograma 2 units and foreign‑plated cars were barred from circulating.
- Allowed vehicles included Holograma 1 with odd plates, Holograma 00 and 0, and exempt categories such as electric and hybrid cars, emergency and public transport units, motorcycles and disability‑plated vehicles.
- Air monitors reported poor conditions driven by PM10, but levels stayed below phase‑1 contingency thresholds, so no additional restrictions were activated.
- Noncompliance risks fines commonly cited at 20–30 UMAs and possible towing, and the program operates Monday through Saturday, with no restrictions on Sundays.
