LAGRANGE, Ind. (AP) — Authorities in a northeastern Indiana county are launching an effort to crack down on motorists who pass stopped school buses.

LaGrange County’s chief deputy prosecutor, Travis Glick, says local enforcement will randomly place police officers on school buses to watch for motorists who violate Indiana’s school bus stop arm law.

He says those officers will radio information about any violators to other officers in marked police cars, who will stop and cite those vehicles.

Glick tells The (Kendallville) News-Sun that school bus stop arm violations are a problem in LaGrange County, where eight cases are pending.

Three siblings were struck and killed in October in Fulton County by a pickup truck as they boarded a school bus that had stopped and lowered its stop arm.
