Is it legal in Missouri to ride in the back of a truck?

In Missouri, it is generally legal for adults to ride in the back of a pickup truck, but there are restrictions for minors. Specifically, children under the age of 18 are prohibited from riding in the cargo area unless certain conditions are met, such as being in a parade or during a farm-related activity. It's always advisable to check local ordinances and ensure safety precautions are taken when riding in the back of a truck.
