Terrifying video shows the moment an out-of-control public bus engulfed in flames crashed into a power pole in Brazil — triggering a massive explosion.

The fiery ordeal erupted when the passenger bus, operated by SPTrans, suffered an electrical malfunction in Sao Paulo on Monday, local outlet Revista Oeste reported.

The driver miraculously managed to evacuate all of his passengers just moments before the flames started to rip through the vehicle’s interior, according to authorities.
