Height Requirements. A child must be at least 4 feet 9 inches tall and age 13 to safely ride in the front seat, according to the Centers for Disease Control and Prevention. If your child reaches this height but hasn't reached his eighth birthday yet, he still needs to sit in a booster in the backseat.
Apparently, the legal requirement is over 80 pounds/age 8. However, kids should sit in the rear seat with a seat belt on until they are at least 13 years old. Some experts say older, but no younger than 13 in the front seat. Keep in mind what is the minimal legal requirement is not necessarily the best safety practice.
