Blazing out-of-control bus catches fire, crashes into power pole: video

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.

Frightening footage showed the abandoned bus then rolling down the street as fire and plumes of black smoke exploded through the vehicle’s roof and windows.

After the blaze was eventually extinguished, all that remained of the gutted bus were the steel frames of the seats.

Police said miraculously no one was injured.

Authorities are still probing the cause of the fiery wreck.
