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 New Mexico, state law does place certain restrictions on riding in the open bed of a truck. According to New Mexico Statutes Section 66-7-364, it is generally unlawful for a person to ride in the bed of a pickup truck on the interstate highways. However, there are exceptions to this rule, such as for employees on duty, during parades, for farm operations within 150 miles of a person's farm, or in cases where the cab is full and the passengers in the open bed are at least 18 years old. It's important to note that local ordinances may impose additional restrictions, and laws can change, so it's advisable to check the most current regulations before allowing passengers to ride in the open bed of a truck.
