PHOENIX -- Arizona is now the first state in the U.S. to regulate indoor trampoline parks, thanks to a bill signed into law Thursday.
HB 2179 is informally called Ty's Law, named after Ty Thomasson who died tragically at a Phoenix trampoline park in 2012.
"This is a very bittersweet law and it will not help my son," Maureen Kerley, Thomasson's mother, said.
Kerley said she hopes the law will spare other mothers and families throughout Arizona from the pain she has felt. Thomasson died from blunt force trauma to the head after diving into a foam pit at an indoor trampoline park.
"It will really help the families out there never to have to, hopefully, live this continual nightmare," she said.
Ty's Law requires trampoline parks to officially register with the state, conduct annual inspections at each site, secure insurance of at least $1 million for bodily injuries and keep mandatory records.
Kerley warned, however, it is not just Arizona's responsibility to keep indoor trampoline park patrons safe while they jump.
"Think before you bounce," she said.
