The incident happened in Redcar, a seaside town in North Yorkshire in the UK, where Gracie Horn fell out of the ride and had to be dragged out of the way of other cars on the Race-O-Rama.
Her mother, Amelia Horn, said she was lucky to be alive.
“Gracie was in one of the cars with her cousin, and as it went round a corner she flew out and was laying on the floor,” she said to Gazette Live.
“The staff member who was running the ride didn’t even notice what had happened.
“Luckily a lady put her hand through the railings and pulled her to safety before one of the cars his Gracie.
“I jumped over the railings while the ride was still going and grabbed her.
“The staff member was crying after realising what happened and said she forgot to secure the kids with a seatbelt.”
The little girl suffered a few cuts and bruises and swollen foot, and is very shaken from the incident.
“If it wasn’t for the lady she could have been killed. I was crying my eyes out thinking about what could have happened, it was so dangerous.
“The manager then told us that Gracie could have as many free goes on the ride as she wanted, which is ridiculous as I’d never let her go on it again,” Amelia said.
