Metal detectors are now permanent fixtures outside three roller coasters at Universal Orlando.

According to the Orlando Sentinel, the detectors are in place "to deter visitors from taking keys, loose change, phones and selfie sticks onto the rides." 

Universal first tested the metal detectors last month, the report said. "It's in response to what people are carrying in their pockets these days," Universal Orlando spokesman Tom Schroder said. "All of us have seen the amount of stuff we carry increase with time. All these things are items that … have no place on high-speed rides. It's just too easy for them to come loose."

Schroder said Universal does not have immediate plans to install them at other rides, said the Orlando Sentinel.
