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.
Vehicle manufacturers also display warnings against allowing children to sit in the front seat due to the danger posed by air bags. Colorado law stipulates that children younger than 1 year and lighter than 20 pounds must ride in the back seat; however, the safest practice is to keep children in the back seat until they turn 13.
