The child restraint law is this: RSMo 307.179 - A child under the age of four or less than 40 pounds must be in an approved car seat. A child four, but less than eight, must be in an approved booster seat, except when they are over 80 pounds and taller than 4â9â. Then they can be in a seat belt. Every child who is between eight and 16 years of age must be in a seat belt regardless of where they are sitting in the vehicle.
