Overview

• The government published two emergency standards—NOM-EM-006-ASEA-2025 for transport and NOM-EM-007-ASEA-2025 for distribution—taking effect Oct. 3.
• All units must install speed governors and GPS with signals tracked from a national monitoring center run by the Energy Ministry, with visible QR identifiers for field checks.
• Companies must file maintenance compliance reports with ASEA and submit equipment to internal inspections and periodic hydrostatic pressure tests, moving beyond prior visual-only reviews.
• Driver training becomes mandatory under a certified competence standard (Conocer), with nationwide application to roughly 35,000 transport and distribution units.
• Compliance windows are four months for transport fleets and for distribution units over 5,000 liters and at least 10 years old, and six months for the rest, alongside coordinated inspections by Sener, ASEA, CNE and SICT; Mexico City has added 13 local controls including lower speed limits, time-and-route restrictions and doubled fines after prosecutors tied the Iztapalapa crash to speeding.
