On the evening of November 7, 2026, a tanker truck carrying approximately 25 tons of anhydrous ammonia overturned on the 150D Ciudad Mendoza-Cordoba highway in Veracruz. The accident occurred near kilometer 265+900 in the Curva del Pocito area, affecting the municipalities of Nogales, Huiloapan, and Rio Blanco.

The driver sustained injuries and received medical attention. In response to the hazardous chemical, authorities from three levels of government, including the National Guard, firefighters, and Civil Protection, established an 80-meter security perimeter and suspended traffic in both directions. 

While officials stated there was no immediate risk to nearby residents, the leak caused significant disruption, paralyzing a major connection between Veracruz and Puebla for nearly 16 hours. Traffic was eventually restored on Sunday morning after emergency crews worked to control the leak and remove the vehicle.
