What age must a child be to ride in the front passenger seat?

The age at which a child can ride in the front passenger seat varies by state. In general, children must be at least 12 years old to ride in the front passenger seat, and they must be properly restrained in a seat belt. However, some states have exceptions to this rule, such as allowing children under the age of 12 to ride in the front passenger seat if they are accompanied by an adult. It is important to check the laws in your state to determine the age at which a child can ride in the front passenger seat.
