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.
It is considered safest and the best practice to keep children in the back seat until they reach age 13. Some states do prohibit transporting children in the front seat until they are 13 years old. If traveling to other states, be aware of their child passenger safety laws.
