Mexico City and the State of Mexico enforced the 'Hoy No Circula' vehicular restriction on April 2, limiting the circulation of vehicles with certain license plate endings and hologram classifications from 5:00 to 22:00 to combat air pollution, according to El Financiero. This measure affects various municipalities including Atizapán de Zaragoza and Coacalco, with exceptions for vehicles holding 00 and 0 holograms.
The vehicle restriction program has been active since at least March 18 and continues throughout the Semana Santa vacation period, with prior enforcement dates including March 19, 21, 25, 26, 28, and April 1, as reported by El Financiero. The regulation systematically restricts vehicles based on the last digit of their license plate and hologram color codes, with red sticker vehicles often targeted for reduced circulation.
Authorities indicate that the restrictions are part of ongoing efforts to improve the air quality within the Valley of Mexico metropolitan area, which experiences frequent pollution challenges. The measures may be intensified during periods of environmental contingencies, signaling a flexible approach to air quality management depending on real-time air pollution levels.
This sustained application of 'Hoy No Circula' restrictions underscores a broader strategy to address urban air pollution and could influence future environmental policies in Mexico City and its neighboring state. Officials and environmental agencies are expected to monitor pollution data closely in the coming weeks to determine the program’s ongoing effectiveness and potential adjustments.
