What is the minimum age to ride as a passenger on a motorcycle driven by someone other than the minor's parents or guardian, or by an authorized adult?

Correct answer: 12 years old.

12 years old. From that age, any driver may carry the child as a passenger if the motorcycle can carry a passenger. Age 7 is enough only when the driver is the child's father, mother, guardian, or an adult authorized by them. The law does not require the child to be 14.
