A school bus crash involving multiple vehicles stalled traffic in Southwest Miami-Dade Monday morning on the first day of classes.
Three cars and a bus collided on U.S. 1 and SW 136th Street after one of the cars rammed the back of the school bus, blocking two westbound lanes, according to Miami-Dade Fire Rescue.
Aerial footage does not show any children exiting the bus following the crash, but officials have yet to confirm whether or not there were students on board.
Rescue vehicles can be seen transporting patients from the scene, but is unclear how many were injured in the crash.
