The devastating crash occurred on Wednesday morning on the highway connecting Cuacnopalan and Oaxaca, as per information provided by local government official Samuel Aguilar Pala. Initial reports indicate that 18 victims succumbed to their injuries at the scene, with three more passing away in nearby hospitals. Local media reports that the incident began when a cement truck attempted to overtake a van but collided with a bus, subsequently resulting in a head-on crash with a transport van. The cement truck then fell into a ravine and erupted into flames. A local journalist captured footage showing plumes of smoke rising and extensive damage to the road infrastructure. Unfortunately, highway accidents have become increasingly common in Mexico, with a similar fatal bus crash occurring earlier this year in Tabasco, reinforcing the urgent need for improved road safety measures.
