Authorities reported that the multiple collision on the Mexico–Querétaro Highway in Huehuetoca occurred when a trailer failed to brake in time, crashing into several vehicles and ending up blocking all north–south lanes. Initial investigations point to excessive speed, insufficient braking distance, and possible driver error as contributing factors. Other elements under review include road conditions, traffic congestion at the time, and a potential mechanical failure of the trailer’s braking system. The exact cause will be confirmed once official investigations are completed.
