An amusement park in California is implementing a chaperone policy after increasing incidents of inappropriate behavior by minors across the industry.

The new policy at California's Great America in Santa Clara went into effect on April 22 and states that all guests ages 15 and younger must be with a chaperone who's at least 21 years or older to be admitted to the amusement park after 4 p.m.

People under 15-years-old who are in the amusement park past 4 p.m. are subject to removal, according to a statement.

Each adult ages 21 and over can chaperone 10 people, according to the policy.

A statement from the amusement park blames bad behavior by minors as a reason for the policy being implemented.

"The safety of our guests and associates has always been our top priority at California's Great America.  Over the past two years, there have been increasing incidents of unruly and inappropriate behavior across our industry and at other major entertainment venues.  We are committed to keeping California's Great America a place where families and friends come together to enjoy a one-of-a-kind park full of fun experiences and immersive entertainment," the statement reads.

"We believe these changes will help ensure that California's Great America continues to have a positive atmosphere where generations of families and friends can gather for a day of safe fun and good food. Millions of guests have counted on us for exactly that, and we will continue to deliver on that promise for generations to come," it continues.
