In almost every case, don't let your child ride in the front seat until he's at least 13 years old — 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.f, despite these very real dangers, you absolutely must put a non-rear-facing child in the front seat, turn off your car's air bag if it has an on-off switch. If your car doesn’t have an on-off switch, you can get one installed.
