Two school buses collided after one school bus stopped after two other vehicles crashed along the Schuylkill Expressway in Philadelphia Monday morning. The wrecks left massive delays.
The vehicles – one turned the wrong direction – collided in the eastbound lanes of Interstate 76 near the South Street Exit shortly before 8 a.m. A large school bus managed to stop short of the wreck but a second smaller bus couldn't stop in time and struck the larger bus, said Pennsylvania State Police.
The wreck left at least four people -- including both bus drivers -- hurt, said firefighters and police.
