What is the weight to sit in the front seat in Missouri?

In Missouri, there is no specific weight requirement to sit in the front seat; however, children under the age of 8 must be secured in an appropriate child safety seat or booster seat, regardless of their weight. Once a child turns 8 years old or reaches a height of 4 feet 9 inches, they are allowed to sit in the front seat with a seatbelt. It's important to follow general safety guidelines and ensure that all passengers are properly restrained.
