What is the general age range for children to use car safety seats?

[LeGarrett]

Car safety seats are generally designed for children under eight years old and weighing less than 36 kilograms. The age until which a child should use a safety seat depends on the traffic regulations of each country, with some based on age and others on the child's weight. Below is relevant information about child safety seats: 1. Most national regulations mandate usage for children under 8 years old, though some specify 6 years old, often with additional weight requirements. Typically, children weighing under 36 kg must use them, while Americans customarily use them until a child reaches 100 lbs (45 kg). 2. China has not yet legislated mandatory child seat usage, so the appropriate age can only be referenced from other countries' standards. Considering the physical characteristics of Chinese children, those under 10 years old weighing less than 36 kg should still use them, while children over 5 years old exceeding 36 kg (excluding obese children) may discontinue usage.
