LIGONIER, Ind. (AP) — A northeastern Indiana foundation is teaming up with a school district to use billboards to remind motorists to stop for school buses when their stop-arms are down.

The Community Foundation of Noble County has agreed to fund the public safety campaign enlisting 13 billboards, in cooperation with the West Noble School Corporation.

The campaign comes after three young siblings were struck and killed in October by a pickup truck as they crossed a Fulton County road to board their school bus.

The (Kendallville) News-Sun reports the billboards will feature a school bus, three children boarding it and the message, “Slow Down and Caution: It’s the law.”

West Noble Transportation Director Jim Best says he hopes the billboards educate motorists to stop when buses are picking up or dropping off students.
