A northern Indiana woman charged in a school bus stop crash that killed three children appeared in court Thursday for her first hearing in the case.

A tragic school bus related accident that killed three Indiana children and critically injured a fourth this week has spurred conversations among school districts and lawmakers about bus and driver safety.

The cameras would be mounted to the outside of school buses and take photos of drivers that pass when the stop arm is deployed.

A voluntary survey from the Indiana Department of Education in 2018 shows more than 3,000 vehicles illegally passed stopped school buses in just one day.

A spokesperson for the NTSB says it's investigating the crash as an isolated incident and looking into the safety of children getting on and off buses.

State Police say three children were struck and killed by a pickup truck in northern Indiana as they were about to board a school bus.

The cameras will be fitted on each of the district's 36 daily route buses and a few alternate buses over the summer.

State officials say the cleaner-burning fuel will decrease children's exposure to particulate matter and lower maintenance costs.

Like most states, Indiana doesn't require seatbelts on school buses. Two bills in the Legislature calling for school bus seatbelts to be required didn't receive committee hearings this year.

The competitive grant program, operated by the state Office of Energy Development, will dole out shares from a $300,000 pool of state money.
