A New Jersey lawmaker is calling for a hearing into school bus safety after a crash left a student and teacher dead and dozens injured.

The chairman of the committee and the senate president both say they support the idea.

The bus carrying 38 fifth-graders and seven adults was traveling on Interstate 80 in Mount Olive when it hit a dump truck.

Investigators are working to determine why a school bus taking a group of fifth-graders on a field trip collided with a dump truck and tipped over on a busy New Jersey highway, killing a student and a teacher.

The crash happened Thursday morning on Interstate 80 in Mount Olive, about 50 miles (80 kilometers) west of New York.

Police declined to release details about how the crash happened, but it occurred on a stretch of highway just past the exit for Waterloo Village, where the group from East Brook Middle School was headed.

The bus wound up on a guardrail close to a spot for emergency vehicles to make a U-Turn onto the highway. A sign there reads “No Turns.”

The impact of the accident tore apart the bus.
