In most states there are laws (statutes) and local ordinances (enacted by cities or towns) that place restrictions on people (and animals) riding in the open (uncovered) bed of a truck. But the specifics of these laws vary significantly from state to state

In approximately 19 states there is no state law against riding in the open bed of truck. These states include:

Laws are constantly evolving—a state legislature may enact a new statute or a city or town may pass a new ordinance and change the law at any time—so always be sure to determine the current status of the law in your state, city, or town.

In California, riding in the open bed of a truck is generally prohibited by state law. California Vehicle Code Section 23116 outlines the restrictions on passengers in the bed of a pickup truck. It states that no person shall ride in the back of a pickup or flatbed motor truck on a highway unless the space is enclosed or has installed vehicle safety restraints. There are exceptions to this rule, such as for an emergency situation, if the vehicle is being operated in a parade, or if the truck is being used in farming operations. Additionally, the law allows for passengers over the age of 18 to ride in the back of a truck if the side racks are at least 46 inches high. However, it's important to note that local ordinances may impose stricter regulations, and the law can change, so it's always advisable to check the most current regulations before allowing passengers to ride in the open bed of a truck.
