State law does not prevent children from riding alone as long as they meet the basic height requirement - in this case, 36 inches with an adult or 42 inches unsupervised. Reuben was around 45 inches tall, Sophia Castillo said.
Cal/OSHA has the authority to stiffen those rules but has never before needed to with a Ferris wheel, Fryer said. Tougher rules could include requiring safety restraints, he said.
Joanne Deocampo, an administrator at the University of California, Davis, Center for Child and Family Studies, said height doesn't translate to a child's emotional ability to handle a ride. A young child can be taller than 42 inches and still be too young to handle the fear of heights that can set in on a Ferris wheel and other tall rides, she said.
