Riders had to be escorted off a roller coaster at Disney's California Adventure on Friday after the ride stopped due to a technical problem, a park spokesman said.
The California Screamin' ride stopped at 7:30 p.m. at the Anaheim park, said park spokeswoman Suzi Brown.
It stopped automatically as it’s supposed to in response to a "minor technical matter" involving the ride, Brown said.
Krista Slade was at the park celebrating her 15th birthday.
"I was really high up. I was scared. It was nerve wracking," Slade said.
Guests were escorted off without issue by park employees, used steps in place on the ride’s tracks for walking down.
Passengers on four vehicles were escorted off. The number of riders was unknown.
They were given cold water when they got off and no one seemed upset, Brown said.
The ride was being tested afterwards.
It was expected to resume normal operations Saturday, Brown said.
California Screamin' is the park's fastest ride with a top speed of up to 55 mph.
Slade tweeted "that was the scariest thing ever, but we are alive."
Disneyland offered the riders a guest pass as compensation for the coaster scare.
