What age and weight should a child be to rid in the front seat US?

In the U.S., children are typically allowed to ride in the front seat at age 13, but laws can vary by state. Additionally, it's important that children meet the weight and height requirements for the vehicle's seat belt; they should weigh at least 80 pounds and be tall enough to sit properly against the seat back with the seat belt fitting correctly. Always check local regulations and guidelines for the safest practices.
