In CA at what age can a child sit in the front seat of car?

In California, there's no specific age limit for children riding in the front seat of a car. However, children must be properly restrained in a car seat or booster seat according to their age and weight as mandated by California law. Until they meet the height and weight requirements to use just a seatbelt, they cannot sit in the front seat. This usually means they must be at least 8 years old and 4'9" tall.
