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.
In almost every case, don't let your child ride in the front seat until he's at least 13 years old â and passenger safety organizations such as SafetyBeltSafe U.S.A. go even further and recommend keeping your child in the backseat until he's old enough to drive himself.n a head-on crash (the most common â and deadly â type of collision), a child in the front seat can be thrown into your car's dashboard or through the windshield. Even if he's properly buckled in, he's at much greater risk of being hurt by objects intruding into the car in the front than in the back.
