MUNSTER, Ind. (AP) — Indiana officials are working to ensure the safety of amusement rides in the state.

The (Northwest Indiana) Times reports that the elevator and amusement ride division of the Indiana Department of Homeland Security is responsible for inspecting all mechanical amusement rides in the state once a year.

Michigan-based Skerbeck Entertainment Group provides amusement rides for the LaPorte County Fair. The company’s director of marketing Sonja Skerbeck says there haven’t been significant incidents on their rides in recent years. However, she says the company has seen an increasing problem with cellphone usage on rides.

She says some riders will use their phone on a ride and a few have lost grip of their device, leading to minor injuries. She says because of the incidents, cellphones aren’t allowed on certain rides.
