Overview

• New limits set a 30 km/h maximum for units carrying dangerous materials, ban vehicles over 40,000 liters from the capital, restrict loads above 20,000 liters to 22:00–05:00 on primary roads, and bar more than 10,000 liters from secondary streets.
• Enforcement will include mobile speed radars at the five main entries to the city (México–Pachuca, –Querétaro, –Toluca, –Cuernavaca, –Puebla), random inspection points, and doubled fines for violations.
• Compliance steps add an E12 license requirement with a hazardous-materials driving course, ASEA-authorized technical inspections, proposed verifier reports under NOM-007-SESH-2010, and internal civil-protection programs for gas and hydrocarbon distribution.
• Officials say the package relies on modifications to the city’s traffic regulations rather than new laws, with operational rollouts expected in the coming days as agencies coordinate joint checks and potential permit revocations for repeat offenders.
• Prosecutors report initial forensic findings pointing to excessive speed with no road defects or mechanical failures; final peritaje results are due next week, the death toll stands at 31, and the president says federal energy and transport secretariats will unveil a nationwide standard on Thursday as a Morena deputy advances a bill to fix federal circulation hours.
