Houston bus union pushes new seat belt laws after deadly crash

As the memorial grows for four students involved in a deadly school bus crash in Houston, the bus union is calling for stringent new seat belt laws in Texas.

The Houston Educational Support Personnel Union held a press conference this morning to call for seat belts in all Texas school buses after two students were killed and two were injured Tuesday morning when their bus plunged off the 610 Loop at Telephone Rd.

Louisa Pacheco, the bus driver at the center of that deadly accident, said it was a miracle she survived the crash and credits her safety belt in protecting her as the bus hurdled to the feeder road below.
