(AP) — Nebraska schools would have to conduct at least three tornado drills a year and establish a response plan for when tornado sirens are sounded as part of a new bill in the Legislature.

Sen. John Murante of Gretna said Thursday that he introduced the measure after speaking with students and administrators in his district.

Murante says many schools already have tornado-response plans, but are concerned that they aren’t running enough drills. He says the state currently requires fire drills, but has no rules in place for tornadoes.

The bill would require schools to post routes to tornado shelters and practice moving students in an orderly fashion.
